Pharmacological Properties

Pharmacodynamics

Olspres N is a combination medication containing olmesartan medoxomil, an angiotensin II receptor blocker, and hydrochlorothiazide, a thiazide diuretic. The combination of these components exerts an additive antihypertensive effect, resulting in a greater reduction in arterial blood pressure than with either component administered alone.

Administration of Olspres N once daily provides effective and smooth reduction of arterial blood pressure over 24 hours until the next dose.

Olmesartan Medoxomil

Olmesartan medoxomil is a selective angiotensin II receptor antagonist (AT1 subtype) intended for oral administration. Angiotensin II is the primary vasoactive hormone of the renin-angiotensin-aldosterone system and plays a key role in the pathophysiology of arterial hypertension. It causes vasoconstriction, induces synthesis and secretion of aldosterone, stimulates cardiac activity, and promotes sodium reabsorption by the kidneys. Olmesartan inhibits the effects of angiotensin II on vasoconstriction and aldosterone secretion by blocking AT1 receptors in tissues, including vascular smooth muscle and adrenal glands. The action of olmesartan is independent of the source or pathway of angiotensin II synthesis. Selective binding of olmesartan to angiotensin II AT1 receptors leads to increased plasma renin levels and concentrations of angiotensin I and angiotensin II, as well as a slight decrease in plasma aldosterone concentration.

In patients with arterial hypertension, olmesartan medoxomil provides sustained, dose-dependent reduction in arterial blood pressure. No signs of arterial hypotension after the first dose (first-dose effect), tachyphylaxis during prolonged use, or rebound hypertension after abrupt discontinuation have been observed.

Once-daily administration of olmesartan medoxomil provides effective and smooth reduction of arterial blood pressure over 24 hours until the next dose. When administered once daily, its antihypertensive effect is approximately equivalent to that achieved with twice-daily administration at the same total daily dose.

A significant antihypertensive effect is observed within 2 weeks of treatment. With continuous therapy, maximum reduction in arterial blood pressure is achieved within 8 weeks of treatment initiation.

The effect of olmesartan medoxomil on mortality and frequency of complications has not been established.

Available data from the randomized trial of olmesartan use and prevention of diabetic microalbuminuria (ROADMAP), involving 4447 patients with type 2 diabetes and normal albuminuria levels and at least one additional cardiovascular risk factor, aimed to determine whether olmesartan therapy could delay the onset of microalbuminuria. During a mean follow-up period of 3.2 years, patients received either olmesartan or placebo in addition to other antihypertensive agents, except ACE inhibitors or ARBs.

In the primary endpoint of the study, a significant reduction in the risk of developing microalbuminuria was demonstrated with olmesartan use. After adjusting for differences in blood pressure levels, this risk reduction was no longer statistically significant. Microalbuminuria developed in 8.2% (178 out of 2160) of patients in the olmesartan group and in 9.8% (210 out of 2139) in the placebo group.

In the secondary endpoint, cardiovascular events occurred in 96 patients (4.3%) receiving olmesartan and in 94 patients (4.2%) receiving placebo. The incidence of cardiovascular mortality was higher in the olmesartan group than in the placebo group (15 patients (0.7%) vs. 3 patients (0.1%)), despite similar rates of non-fatal stroke (14 patients (0.6%) vs. 8 patients (0.4%)), non-fatal myocardial infarction (17 patients (0.8%) vs. 26 patients (1.2%)), and non-cardiovascular mortality (11 patients (0.5%) vs. 12 patients (0.5%)). Overall mortality was numerically higher in the olmesartan group (26 patients (1.2%) vs. 15 patients (0.7%)), primarily due to higher cardiovascular mortality.

In the ORIENT trial (The Olmesartan Reducing Incidence of End-stage Renal Disease in Diabetic Nephropathy Trial), the effect of olmesartan on renal and cardiovascular outcomes was studied in 577 randomized patients in Japan and China with type 2 diabetes and overt nephropathy. During a mean follow-up period of 3.1 years, patients received either olmesartan or placebo in addition to other antihypertensive agents, including ACE inhibitors.

The primary composite endpoint (time to first occurrence of doubling of serum creatinine, end-stage renal disease, or all-cause mortality) was reached in 116 patients in the olmesartan group (41.1%) and in 129 patients in the placebo group (45.4%) (HR 0.97 (95% CI 0.75–1.24); p = 0.791). The secondary composite cardiovascular endpoint occurred in 40 patients receiving olmesartan (14.2%) and in 53 patients receiving placebo (18.7%). This composite cardiovascular endpoint included cardiovascular mortality in 10 (3.5%) patients receiving olmesartan and in 3 (1.1%) patients receiving placebo; overall mortality was 19 (6.7%) and 20 (7.0%), non-fatal stroke occurred in 8 (2.8%) and 11 (3.9%), and non-fatal myocardial infarction in 3 (1.1%) and 7 (2.5%), respectively.

Hydrochlorothiazide

Hydrochlorothiazide is a thiazide diuretic. The mechanism of antihypertensive action of thiazide diuretics is not fully understood. Thiazides affect electrolyte reabsorption in renal tubules, thereby enhancing excretion of sodium and chloride (approximately to a similar extent). Acting as a diuretic, hydrochlorothiazide reduces plasma volume, leading to increased plasma renin activity and aldosterone secretion, increased urinary excretion of potassium and bicarbonate, and decreased serum concentrations of these electrolytes. Since the link between renin levels and aldosterone secretion is mediated by angiotensin II, the urinary potassium losses caused by thiazide diuretics may be reduced when hydrochlorothiazide is used in combination with an angiotensin II receptor blocker. Diuresis begins approximately 2 hours after administration, maximum effect is reached within about 4 hours, and the effect lasts for 6–12 hours.

According to epidemiological data, long-term use of hydrochlorothiazide as monotherapy reduces the risk of cardiovascular complications and mortality from them.

Clinical Efficacy and Safety

Combined Therapy with Olmesartan Medoxomil and Hydrochlorothiazide

In combined therapy with olmesartan medoxomil and hydrochlorothiazide, the antihypertensive effect is additively enhanced and generally exceeds the effects of each component used separately.

Based on pooled data from placebo-controlled trials, treatment with olmesartan medoxomil/hydrochlorothiazide at doses of 20/12.5 mg and 20/25 mg resulted in mean placebo-corrected reductions in systolic/diastolic blood pressure at the end of the dosing interval of -12/-7 mm Hg and -16/-9 mm Hg, respectively. Age and gender did not have a clinically significant impact on the efficacy of combined therapy with olmesartan medoxomil and hydrochlorothiazide.

When hydrochlorothiazide at doses of 12.5 mg and 25 mg was used in patients with insufficient response to olmesartan medoxomil monotherapy at 20 mg, additional reductions in mean 24-hour systolic/diastolic blood pressure measured by ambulatory blood pressure monitoring were observed (-7/-5 mm Hg and -12/-7 mm Hg compared to baseline values achieved with olmesartan medoxomil monotherapy). When blood pressure was measured by conventional methods, additional reductions in mean systolic/diastolic blood pressure at the end of the dosing interval were -11/-10 mm Hg and -16/-11 mm Hg, respectively (compared to baseline values).

Combined therapy with olmesartan medoxomil and hydrochlorothiazide remained effective over a prolonged treatment period (1 year). Rebound hypertension was not observed upon discontinuation of olmesartan medoxomil (whether used in combination with hydrochlorothiazide or alone).

The effect of the combined olmesartan medoxomil and hydrochlorothiazide preparation on cardiovascular complications and mortality from them is currently unknown.

Hydrochlorothiazide

Non-melanoma Skin Cancer

Available epidemiological data indicate a cumulative dose-dependent association between hydrochlorothiazide use and the development of non-melanoma skin cancer. In a study involving 1,430,833 and 172,462 individuals, respectively, 71,533 cases of basal cell carcinoma and 8,629 cases of squamous cell carcinoma of the skin were recorded. High cumulative doses of hydrochlorothiazide (≥50,000 mg) were associated with an adjusted risk ratio of 1.29 (95% CI: 1.23–1.35) for basal cell carcinoma and 3.98 (95% CI: 3.68–4.31) for squamous cell carcinoma. A clear cumulative dose effect was observed for both basal cell and squamous cell skin cancers. Another study indicated a possible association between lip cancer (squamous cell carcinoma of the skin) and exposure to hydrochlorothiazide: 633 cases of lip cancer in a study involving 63,067 individuals using a risk-set sampling strategy. A cumulative dose effect was demonstrated with an adjusted risk ratio of 2.1 (95% CI: 1.7–2.6), increasing to 3.9 (3.0–4.9) with high-dose exposure (~25,000 mg) and to 7.7 (5.7–10.5) with the highest cumulative dose (~100,000 mg) (see section "Special Warnings and Precautions for Use").

Other Information

Concomitant use of ACE inhibitors and angiotensin II receptor blockers was evaluated in two large-scale randomized controlled trials (ONTARGET [ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial] and VA NEPHRON-D [The Veterans Affairs Nephropathy in Diabetes]).

ONTARGET was a study conducted in patients with a history of cardiovascular or cerebrovascular disease or type 2 diabetes with evidence of target organ damage. VA NEPHRON-D was a study conducted in patients with type 2 diabetes and diabetic nephropathy. The studies did not demonstrate a significant beneficial effect on renal and/or cardiovascular outcomes or mortality, while the risk of hyperkalemia, acute kidney injury, and/or hypotension was increased compared to monotherapy. Given the similarity of pharmacodynamic properties, these findings are also applicable to other ACE inhibitors and angiotensin II receptor blockers.

Concomitant use of ACE inhibitors and angiotensin II receptor blockers is contraindicated in patients with diabetic nephropathy.

ALTITUDE (Aliskiren Trial in Type 2 Diabetes Using Cardiovascular and Renal Disease Endpoints) was a study designed to evaluate the positive effect of adding aliskiren to standard therapy with ACE inhibitors or angiotensin II receptor blockers in patients with type 2 diabetes and chronic kidney disease, cardiovascular disease, or both. The study was terminated early due to an increased risk of adverse outcomes. Cardiovascular mortality and incidence of stroke were higher in the aliskiren group than in the placebo group, and reports of adverse events and serious adverse events (hyperkalemia, hypotension, and renal dysfunction) were more frequent in the aliskiren group than in the placebo group.

Pharmacokinetics

Absorption and Distribution

Olmesartan Medoxomil

Olmesartan medoxomil is a prodrug. It is rapidly converted into the pharmacologically active metabolite olmesartan by esterases in the intestinal mucosa and portal blood during absorption from the gastrointestinal tract. Neither olmesartan medoxomil nor the medoxomil side group is detected unchanged in plasma or excreta. The mean absolute bioavailability of olmesartan in tablet form is 25.6%. The mean maximum plasma concentration (Cmax) of olmesartan is reached approximately 2 hours after oral administration. After single oral doses up to 80 mg, plasma concentrations of olmesartan increase approximately in proportion to the dose. Food has minimal effect on the bioavailability of olmesartan; therefore, olmesartan medoxomil can be administered independently of food intake. No clinically significant differences in olmesartan pharmacokinetics between genders have been observed. Olmesartan is highly bound to plasma proteins (99.7%), but the risk of clinically significant interactions with other drugs due to competition for plasma protein binding is low (evidenced by the absence of clinically significant interaction between olmesartan medoxomil and warfarin). Olmesartan binds minimally to blood cells. The mean volume of distribution after intravenous administration is small (16–29 L).

Hydrochlorothiazide

When olmesartan medoxomil is administered in combination with hydrochlorothiazide, the median time to reach Cmax of hydrochlorothiazide in plasma is 1.5–2 hours. Hydrochlorothiazide is 68% bound to plasma proteins, and its apparent volume of distribution is 0.83–1.14 L/kg.

Biotransformation and Elimination

Olmesartan Medoxomil

The total plasma clearance of olmesartan is approximately 1.3 L/hour (coefficient of variation 19%) and is relatively low compared to hepatic blood flow (approximately 90 L/hour). After a single oral dose of radiolabeled (14C) olmesartan medoxomil, 10–16% of the radioactive label was recovered in urine (mostly within 24 hours after administration); the remaining radioactivity was found in feces. Considering the systemic bioavailability of the drug is 25.6%, it can be calculated that absorbed olmesartan is eliminated both renally (approximately 40%) and via the hepatobiliary system (approximately 60%). All radioactivity detected in excreta was accounted for by olmesartan. No other significant metabolites were identified. Olmesartan does not participate significantly in enterohepatic recirculation.

Since a large portion of olmesartan is excreted via bile, its use is contraindicated in patients with biliary obstruction. The terminal elimination half-life of olmesartan after repeated oral administration ranges from 10 to 15 hours. Steady-state conditions are achieved after the first few doses; no further accumulation was observed after 14 days of repeated administration. Renal clearance is approximately 0.5–0.7 L/hour and is independent of dose.

Hydrochlorothiazide

Hydrochlorothiazide is not metabolized in humans and is almost entirely excreted unchanged in urine. After oral administration, approximately 60% of the dose is excreted unchanged within 48 hours. Renal clearance is approximately 250–300 mL/min. The terminal elimination half-life is about 10–15 hours.

Combination of Olmesartan Medoxomil with Hydrochlorothiazide

When hydrochlorothiazide is administered in combination with olmesartan medoxomil, its systemic bioavailability is reduced by approximately 20%, but this reduction is not clinically significant. The pharmacokinetics of olmesartan when administered in combination with hydrochlorothiazide are not altered.

Pharmacokinetics in Specific Patient Populations

Elderly Patients (aged 65 years and older)

In elderly hypertensive patients (65–75 years), the steady-state area under the pharmacokinetic curve (AUC) of olmesartan is approximately 35% higher than in younger patients, and in patients aged ≥75 years, it is approximately 44% higher.

Available data suggest that systemic clearance of hydrochlorothiazide is lower in elderly individuals (both healthy and hypertensive) compared to healthy volunteers.

Renal Impairment

In patients with mild, moderate, and severe renal impairment, the steady-state AUC of olmesartan is 62%, 82%, and 179% higher, respectively, than in healthy volunteers. The elimination half-life of hydrochlorothiazide is prolonged in patients with renal impairment.

Hepatic Impairment

After a single oral dose, the AUC of olmesartan in patients with mild and moderate hepatic impairment was 6% and 65% higher, respectively, than in healthy control subjects with similar demographic characteristics. In healthy volunteers and patients with mild and moderate hepatic impairment, the unbound fraction of olmesartan 2 hours after administration was 0.26%, 0.34%, and 0.41%, respectively. After repeated dosing, the mean AUC of olmesartan in patients with moderate hepatic impairment was 65% higher than in healthy control subjects. Cmax values of olmesartan in patients with hepatic impairment and healthy volunteers were similar. The efficacy of olmesartan medoxomil has not been established in patients with severe hepatic impairment. Hepatic impairment does not significantly affect the pharmacokinetics of hydrochlorothiazide.

Interaction with Other Medicinal Products

Bile Acid Sequestrant Colesevelam

Concomitant administration of 40 mg olmesartan medoxomil and 3750 mg colesevelam hydrochloride resulted in a 28% reduction in Cmax and a 39% reduction in AUC for olmesartan. A smaller effect, with reductions in Cmax and AUC of 4% and 15%, respectively, was observed when olmesartan medoxomil was administered 4 hours before colesevelam hydrochloride. The elimination half-life of olmesartan was reduced by 50–52%, regardless of whether the drugs were administered together or olmesartan was given 4 hours before colesevelam hydrochloride.

Preclinical Safety Data

Available information on the toxic effects of the combination of olmesartan medoxomil and hydrochlorothiazide was evaluated in studies involving repeated oral administration in rats and dogs (up to 6 months).

As with administration of the individual components or other drugs of the same class, the toxic effects of this combination are primarily directed at the kidneys. Functional kidney changes (increased blood urea nitrogen and serum creatinine) were observed with the combination of olmesartan medoxomil and hydrochlorothiazide. In rats and dogs receiving high-dose combinations, renal degeneration and regeneration were observed, possibly due to impaired renal hemodynamics (reduced renal blood flow due to arterial hypotension combined with hypoxia and tubular cell degeneration). Additionally, the combination of olmesartan medoxomil and hydrochlorothiazide led to decreased erythrocyte parameters (erythrocyte count, hemoglobin, and hematocrit) and reduced heart weight in rats. These findings have also been observed with other AT1 receptor blockers and ACE inhibitors. They are likely due to the pharmacological action of olmesartan medoxomil at high doses and are not observed when the drug is used at recommended therapeutic doses.

In genotoxicity studies of the combination of olmesartan medoxomil and hydrochlorothiazide, as well as of the individual components, no signs of clinically significant genotoxicity were observed.

The carcinogenic potential of the combination of olmesartan medoxomil and hydrochlorothiazide has not been studied, as no signs of carcinogenic effects of the individual components have been observed in clinical practice.

No teratogenic effects were observed in mice and rats administered olmesartan medoxomil in combination with hydrochlorothiazide. As expected for drugs of this class, toxic effects on the fetus, manifested as a significant reduction in fetal body weight, were observed in rats treated with the combination of olmesartan medoxomil and hydrochlorothiazide during pregnancy (see sections "Contraindications" and "Use in Pregnancy or Lactation").

Clinical characteristics.

Indications.

Essential hypertension.

The combined medicinal product Olspres N is intended for adult patients in whom treatment with olmesartan medoxomil alone does not provide adequate reduction of arterial pressure.

Contraindications.

  • Hypersensitivity to the active substances, to any of the excipients, or to other sulfonamide derivatives (hydrochlorothiazide is also a sulfonamide derivative).
  • Severe renal impairment (creatinine clearance < 30 mL/min).
  • Persistent hypokalemia, hypercalcemia, hyponatremia, and clinically evident hyperuricemia.
  • Severe hepatic impairment, cholestasis, and obstructive biliary disorders.
  • Pregnancy or planned pregnancy.
  • Concomitant use of Olspres N with medicinal products containing aliskiren is contraindicated in patients with diabetes mellitus or renal impairment (eGFR <60 mL/min/1.73 m²).

Interaction with other medicinal products and other forms of interaction.

Concomitant use not recommended

Lithium preparations.

Concomitant use of lithium with angiotensin-converting enzyme inhibitors and sometimes with angiotensin II receptor antagonists has been associated with reversible increases in serum lithium concentration and its toxic effects. Moreover, thiazides reduce renal clearance of lithium, thereby increasing the risk of lithium toxicity when used with hydrochlorothiazide. Therefore, concomitant use of Olspres N with lithium is not recommended. In patients who require simultaneous administration of these agents, serum lithium concentrations should be closely monitored during treatment.

Concomitant use requiring caution

  • Baclofen.* Hypotensive effect may be enhanced.

Non-steroidal anti-inflammatory drugs (NSAIDs).

NSAIDs (e.g., acetylsalicylic acid (>3 g/day), COX-2 inhibitors, and non-selective NSAIDs) may attenuate the antihypertensive effects of thiazide diuretics and angiotensin II receptor blockers. In some patients with renal impairment (e.g., dehydrated patients or elderly patients with kidney disease), the use of angiotensin II receptor blockers together with cyclooxygenase-inhibiting agents may exacerbate renal dysfunction, including acute renal failure, which is usually reversible. Therefore, these agents should be used concomitantly with caution, especially in elderly patients. Patients should maintain adequate fluid intake. Furthermore, renal function should be monitored carefully after initiation of combined therapy and at regular intervals thereafter.

Concomitant use requiring special attention

Amifostine.

Antihypertensive effect may be enhanced.

Other antihypertensive agents.

The antihypertensive effect of Olspres N may be enhanced when used concomitantly with other agents that lower blood pressure.

Ethanol, barbiturates, narcotic analgesics, and antidepressants.

Orthostatic hypotension may be intensified.

Potential interactions with olmesartan medoxomil.

Concomitant use not recommended

ACE inhibitors, angiotensin II receptor blockers, or aliskiren.

Clinical data indicate that dual blockade of the renin-angiotensin-aldosterone system (RAAS), associated with the combined use of ACE inhibitors and angiotensin II receptor blockers or aliskiren, increases the incidence of adverse events such as hypotension, hyperkalemia, and renal dysfunction (including acute renal failure), compared to monotherapy with a single RAAS-acting agent.

Medicinal products affecting blood potassium concentration.

Based on experience with other agents acting on the renin-angiotensin system, serum potassium concentration may increase when potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes, or other agents capable of increasing serum potassium (e.g., heparin, ACE inhibitors) are used concomitantly. When Olspres N is prescribed together with potassium-affecting agents, serum potassium levels should be monitored.

Medicinal product colesevelam, a bile acid sequestrant.

Concomitant use of the bile acid sequestrant colesevelam hydrochloride reduces systemic exposure and peak plasma concentration of olmesartan, as well as its elimination half-life. Administration of olmesartan medoxomil at least 4 hours before colesevelam hydrochloride reduces the effect of this drug interaction. Consideration should be given to administering olmesartan medoxomil at least 4 hours before colesevelam hydrochloride.

Additional information.

A moderate reduction in the bioavailability of olmesartan medoxomil has been observed after treatment with antacids (magnesium-aluminum hydroxide). Olmesartan medoxomil does not have a significant effect on the pharmacokinetics and pharmacodynamics of warfarin or the pharmacokinetics of digoxin. No clinically significant changes in the pharmacokinetics of either drug were observed when olmesartan medoxomil was co-administered with pravastatin. In vitro studies did not show clinically significant inhibition by olmesartan of the activity of human cytochrome P450 isoenzymes IA1/2, IIA6, IIC8/9, IIC19, IID6, IIE1, and IIIA4; olmesartan either had minimal inductive effects or no effect at all on animal cytochrome P450 isoenzymes. Therefore, clinically significant interactions between olmesartan and medicinal products metabolized by the aforementioned cytochrome P450 isoenzymes are not expected.

Potential interactions with hydrochlorothiazide.

Concomitant use not recommended

Medicinal products affecting blood potassium concentration.

The hypokalemic effect of hydrochlorothiazide may be enhanced when used concomitantly with other medicinal products causing potassium loss and hypokalemia (e.g., potassium-wasting diuretics, laxatives, corticosteroids, ACTH, amphotericin, carbenoxolone, sodium penicillin G, and salicylate derivatives). Therefore, concomitant use of hydrochlorothiazide with these agents is not recommended.

Concomitant use requiring caution

Calcium salts.

Thiazide diuretics may increase serum calcium concentration by reducing calcium excretion. If calcium supplements are necessary, serum calcium levels should be monitored and the calcium dose adjusted accordingly.

Cholestyramine and colestipol.

The use of anion-exchange resins slows the absorption of hydrochlorothiazide.

Cardiac glycosides.

The use of cardiac glycosides increases the risk of arrhythmias in the presence of thiazide-induced hypokalemia and hypomagnesemia.

Medicinal products whose efficacy depends on changes in serum potassium concentration.

When Olspres N is used concomitantly with medicinal products whose efficacy depends on changes in serum potassium concentration (e.g., cardiac glycosides and antiarrhythmic agents), or with agents that may cause torsade de pointes (ventricular tachycardia), including certain antiarrhythmic agents, regular monitoring of serum potassium concentration and ECG is recommended:

  • Class Ia antiarrhythmic agents (e.g., quinidine, hydroquinidine, disopyramide);
  • Class III antiarrhythmic agents (e.g., amiodarone, sotalol, dofetilide, ibutilide);
  • Certain antipsychotics (e.g., thioridazine, chlorpromazine, levomepromazine, trifluoperazine, zuclopenthixol, sulpiride, sultopride, amisulpride, tiapride, pimozide, haloperidol, droperidol);
  • Others (e.g., bepridil, cisapride, difemanil, intravenous erythromycin, halofantrine, mizolastine, pentamidine, sparfloxacin, terfenadine, intravenous vinca alkaloids).

Non-depolarizing skeletal muscle relaxants (e.g., tubocurarine).

Hydrochlorothiazide may enhance the effect of non-depolarizing skeletal muscle relaxants.

Anticholinergic agents (e.g., atropine and biperiden).

By reducing gastrointestinal motility and gastric emptying, anticholinergic agents may increase the bioavailability of thiazide diuretics.

Antidiabetic medicinal products (oral agents and insulin).

Thiazide therapy may affect glucose tolerance. Dose adjustment of antidiabetic agents may be necessary.

Metformin.

Metformin should be used with caution due to the risk of lactic acidosis caused by functional renal impairment, which may occasionally occur with hydrochlorothiazide use.

Beta-blockers and diazoxide.

The hyperglycemic effect of beta-blockers and diazoxide may be enhanced by thiazides.

Pressor amines (e.g., noradrenaline).

The effectiveness of pressor amines may be reduced.

Medicinal products used to treat gout (probenecid, sulfinpyrazone, and allopurinol).

Since hydrochlorothiazide may occasionally increase serum uric acid concentration, dose adjustment of uricosuric agents used to treat gout may be necessary. Additionally, the dose of probenecid or sulfinpyrazone may sometimes need to be increased. When allopurinol is used concomitantly with thiazides, the frequency of allergic reactions to allopurinol may increase.

Amantadine.

Thiazides may increase the risk of adverse reactions caused by amantadine.

Antineoplastic agents (e.g., cyclophosphamide, methotrexate).

Thiazides may reduce renal excretion of anticancer drugs and enhance their myelosuppressive effects.

Salicylates.

When high doses of salicylates are administered, hydrochlorothiazide may potentiate their toxic effects on the central nervous system.

Metildopa.

Published reports describe isolated cases of hemolytic anemia associated with the use of hydrochlorothiazide in combination with methyldopa.

Cyclosporine.

Concomitant use of thiazides with cyclosporine may increase the risk of hyperuricemia and complications similar to gout.

Tetracycline.

Concomitant use of thiazides with tetracycline increases the risk of tetracycline-induced uremia. This effect probably does not apply to doxycycline.

Carbamazepine.

Due to the risk of symptomatic hyponatremia, clinical and biological monitoring is required.

Iodinated contrast agents.

Diuretics may lead to patient dehydration; therefore, adequate hydration should be ensured before administering high doses of iodinated contrast agents to reduce the risk of acute renal failure.

Special precautions for use.

Reduction in circulating blood volume.

In patients with reduced circulating blood volume and/or low sodium levels due to intensive diuretic therapy, low-salt diet, diarrhea, or vomiting, clinically significant arterial hypotension may occur, especially after the first dose of the drug. Before initiating treatment with Olspres N, these conditions should be corrected.

Other conditions associated with activation of the renin-angiotensin-aldosterone system (RAAS).

Patients in whom vascular tone and renal function are highly dependent on RAAS activity (e.g., those with severe congestive heart failure or renal disease, including renal artery stenosis) may experience acute arterial hypotension, azotemia, oliguria, or, in rare cases, acute renal failure when treated with drugs affecting this system.

Renovascular hypertension.

The use of drugs affecting the RAAS in patients with bilateral renal artery stenosis or stenosis of the artery of a single functioning kidney is associated with an increased risk of severe arterial hypotension and renal failure.

Renal impairment and kidney transplantation.

Olspres N is contraindicated in patients with severe renal impairment (creatinine clearance <30 mL/min) (see section "Contraindications"). Dose adjustment is not required in patients with mild to moderate renal impairment (creatinine clearance ≥30 mL/min but <60 mL/min). However, the drug should be used with caution in such patients, and periodic monitoring of serum potassium, creatinine, and uric acid concentrations is recommended. Azotemia due to thiazide diuretics may occur in patients with renal impairment. If progressive renal failure becomes evident, the treatment regimen should be carefully reviewed and diuretics discontinued if necessary. There is no clinical experience with the use of Olspres N in patients who have recently undergone kidney transplantation.

Dual blockade of the renin-angiotensin-aldosterone system (RAAS).

Concomitant use of ACE inhibitors, angiotensin II receptor blockers, or aliskiren increases the risk of arterial hypotension, hyperkalemia, and impaired renal function (including acute renal failure). Therefore, dual RAAS blockade with concomitant use of ACE inhibitors, angiotensin II receptor blockers, or aliskiren is not recommended.

If dual blockade therapy is absolutely necessary, it should be administered only under specialist supervision and with close monitoring of renal function, electrolyte levels, and blood pressure.

Patients with diabetic nephropathy should not receive concomitant treatment with ACE inhibitors and angiotensin II receptor blockers.

Hepatic impairment.

There is no experience with the use of olmesartan medoxomil in patients with severe hepatic impairment. Additionally, minor disturbances in fluid and electrolyte balance caused by thiazide therapy may precipitate hepatic coma in patients with hepatic impairment or progressive liver disease. Therefore, Olspres N should be used with caution in patients with mild to moderate hepatic impairment. Olspres N is contraindicated in patients with severe hepatic impairment, cholestasis, or biliary obstruction.

Aortic valve stenosis and mitral valve stenosis, hypertrophic obstructive cardiomyopathy.

As with other vasodilators, olmesartan medoxomil should be used with caution in patients with aortic valve stenosis or mitral valve stenosis, as well as in those with obstructive hypertrophic cardiomyopathy.

Primary hyperaldosteronism.

Patients with primary hyperaldosteronism generally do not respond to antihypertensive agents that suppress the renin-angiotensin system. Therefore, Olspres N is not recommended for such patients.

Metabolic and endocrine effects.

Thiazide drugs may impair glucose tolerance. Insulin or oral hypoglycemic agents may require dose adjustment in diabetic patients. Thiazide use may also unmask latent diabetes mellitus.

Thiazide diuretics may cause increases in serum cholesterol and triglyceride levels. In some cases, thiazide use may lead to hyperuricemia or gout. Hydrochlorothiazide may increase serum free bilirubin levels.

Hydrochlorothiazide

Acute respiratory toxicity.

Very rare, severe cases of acute respiratory toxicity, including acute respiratory distress syndrome (ARDS), have been reported after hydrochlorothiazide administration. Pulmonary edema usually develops within minutes or hours after taking hydrochlorothiazide. Initial symptoms include dyspnea, fever, worsening pulmonary condition, and hypotension. If ARDS is suspected, hydrochlorothiazide should be discontinued immediately and appropriate treatment initiated. Hydrochlorothiazide should not be prescribed to patients who previously experienced ARDS after taking hydrochlorothiazide.

Electrolyte disturbances.

As with any diuretic, serum electrolyte levels should be monitored at regular intervals during hydrochlorothiazide therapy. Thiazide drugs, including hydrochlorothiazide, may cause disturbances in fluid and electrolyte balance (including hypokalemia, hyponatremia, and hypochloremic alkalosis). Signs of fluid and electrolyte imbalance include dry mouth, thirst, weakness, prolonged sleep, drowsiness, restlessness, muscle pain or cramps, muscle fatigue, arterial hypotension, oliguria, tachycardia, and gastrointestinal disturbances such as nausea and vomiting. The risk of hypokalemia is highest in patients with liver cirrhosis, a sudden increase in diuresis, inadequate oral electrolyte intake, or concomitant use of corticosteroids and ACTH. On the other hand, blockade of angiotensin II (AT1) receptors by olmesartan medoxomil, a component of Olspres N, may lead to hyperkalemia, particularly in patients with renal impairment and/or heart failure, as well as in patients with diabetes mellitus. Serum potassium levels should be appropriately monitored in these patients. Olspres N should be used with caution when administered concomitantly with potassium supplements, potassium-sparing diuretics, potassium-containing salt substitutes, or other drugs that may increase serum potassium levels. There are no data indicating that olmesartan medoxomil can prevent or mitigate diuretic-induced hyponatremia. Chloride deficiency is usually mild and does not require specific treatment. Thiazides may reduce urinary calcium excretion and cause a slight and transient increase in serum calcium concentration in the absence of any calcium metabolism disorders. Hypercalcemia may indicate occult hyperparathyroidism. Thiazides should be discontinued before parathyroid function testing. Thiazides enhance magnesium excretion in urine, potentially leading to hypomagnesemia. Hyponatremia of dilution may occur in edematous patients during hot weather.

Lithium preparations.

As with other drugs containing angiotensin II receptor blockers in combination with thiazides, Olspres N is not recommended for concomitant use with lithium preparations.

Sprue-like enteropathy

In very rare cases, severe chronic diarrhea with significant weight loss has been reported, developing several months or years after starting treatment with olmesartan; this is likely due to a localized delayed hypersensitivity reaction. Intestinal mucosal biopsies in such patients often show villous atrophy. If these symptoms occur in a patient during olmesartan therapy and other probable causes can be excluded, olmesartan therapy should be discontinued immediately and not restarted. If diarrhea does not resolve within one week after stopping the drug, the patient should consult a specialist (e.g., a gastroenterologist).

Acute myopia and secondary angle-closure glaucoma

Hydrochlorothiazide is a sulfonamide and may cause idiosyncratic reactions leading to choroidal effusion with visual field defects, acute transient myopia, and acute attacks of angle-closure glaucoma. Symptoms include acute onset of myopia or eye pain and typically occur within hours to weeks after starting treatment. Untreated acute angle-closure glaucoma may lead to permanent vision loss. Hydrochlorothiazide should be discontinued as soon as possible. If intraocular pressure cannot be controlled, immediate therapeutic or surgical intervention may be necessary. A history of allergy to sulfonamides or penicillin may be a risk factor for developing angle-closure glaucoma (see section "Adverse reactions").

Ethnic differences.

As with other angiotensin II receptor blockers, the antihypertensive effect of olmesartan medoxomil is somewhat less pronounced in Black patients compared to other ethnic groups (possibly due to lower renin levels in Black patients).

Anti-doping testing.

Hydrochlorothiazide, a component of this drug, may cause false-positive results in anti-doping tests.

Pregnancy.

Olspres N is contraindicated in pregnant women or women who are planning to become pregnant. If pregnancy is confirmed during treatment with Olspres N, therapy should be discontinued immediately and, if necessary, replaced with another drug approved for use during pregnancy.

Intestinal angioedema

Cases of intestinal angioedema have been reported in patients taking angiotensin II receptor blockers [including olmesartan] (see section "Adverse reactions"). These patients experienced abdominal pain, nausea, vomiting, and diarrhea. Symptoms resolved after discontinuation of angiotensin II receptor blockers. If intestinal angioedema is diagnosed, olmesartan therapy should be discontinued and appropriate monitoring initiated until symptoms completely resolve.

Other precautions.

Excessive reduction in blood pressure in patients with generalized atherosclerosis, ischemic heart disease, or ischemic cerebrovascular disease may lead to myocardial infarction or stroke.

The risk of allergic reactions to hydrochlorothiazide is higher in patients with a history of allergy or bronchial asthma, although such reactions may also occur in patients without such history.

According to scientific literature, thiazide diuretics may exacerbate or activate systemic lupus erythematosus.

Photosensitivity reactions may occur during treatment with thiazide diuretics. In such cases, discontinuation of the drug is recommended. If the physician considers it necessary to reinitiate treatment, patients should be advised to protect skin areas exposed to sunlight or artificial ultraviolet radiation.

Non-melanoma skin cancer.

An increased risk of non-melanoma skin cancer (basal cell carcinoma and squamous cell carcinoma) associated with higher cumulative doses of hydrochlorothiazide was observed in two epidemiological studies based on data from the Danish National Cancer Registry. The photosensitizing effect of hydrochlorothiazide may be a mechanism underlying the development of non-melanoma skin cancer.

Patients taking hydrochlorothiazide should be informed about the potential risk of non-melanoma skin cancer. Regular skin examinations for new lesions are recommended, and any suspicious skin changes should be reported immediately.

Patients should be informed about possible preventive measures, such as limiting exposure to sunlight and UV radiation and using adequate skin protection when such exposure occurs, to minimize the risk of skin cancer.

Any suspicious skin reactions should be promptly investigated, including histological examination of biopsy specimens.

In patients with a history of non-melanoma skin cancer, reconsideration of hydrochlorothiazide use may be appropriate (see section "Adverse reactions").

If a patient has intolerance to certain sugars, medical advice should be sought before taking this medication.

The drug contains lactose and should not be administered to patients with congenital galactose intolerance, lactase deficiency, or glucose-galactose malabsorption.

Use during pregnancy or breastfeeding.

Pregnancy.

Olmesartan medoxomil.

Angiotensin II receptor blockers are contraindicated in pregnant women or women planning pregnancy.

Epidemiological data on teratogenic risk associated with the use of angiotensin II receptor blockers during the first trimester of pregnancy do not allow definitive conclusions, but a slight increase in risk cannot be excluded. Controlled epidemiological studies have not provided data on teratogenic risk with angiotensin II receptor blockers, but an increased risk of similar effects cannot be ruled out. Except in cases where angiotensin II receptor blockers are used for life-saving reasons, women planning pregnancy should be switched to other antihypertensive agents with proven safety during pregnancy. If pregnancy is diagnosed, angiotensin II receptor blockers should be discontinued immediately, and alternative therapy initiated if necessary.

It has been established that use of angiotensin II receptor blockers during the second and third trimesters of pregnancy may result in fetotoxic effects (impaired renal function, oligohydramnios, delayed skull ossification) and neonatal toxicity (renal failure, arterial hypotension, hyperkalemia).

If angiotensin II receptor blockers are used during the second trimester of pregnancy, ultrasound monitoring of fetal renal function and skull development is recommended.

Newborns whose mothers used angiotensin II receptor blockers should be closely monitored for the development of arterial hypotension.

Hydrochlorothiazide.

Experience with hydrochlorothiazide use during pregnancy, especially in the first trimester, is limited. Experimental animal data are insufficient. Hydrochlorothiazide crosses the placenta. Due to its mechanism of action, hydrochlorothiazide use during the second and third trimesters of pregnancy may impair fetoplacental circulation and adversely affect the fetus and newborn, causing jaundice, electrolyte disturbances, and thrombocytopenia.

Hydrochlorothiazide is not indicated for the treatment of edema in pregnancy, gestational hypertension, or preeclampsia, as it may reduce plasma volume and cause placental hypoperfusion without providing adequate therapeutic benefit.

Hydrochlorothiazide is also not recommended for the treatment of essential hypertension in pregnant women, except in exceptional cases where other drugs cannot be used.

The combination drug olmesartan medoxomil/hydrochlorothiazide is contraindicated in pregnant women or women planning pregnancy.

Breastfeeding period.

Olmesartan medoxomil.

There is currently no information on the use of Olspres N during breastfeeding; therefore, the drug should not be administered to breastfeeding women. Alternative drugs with proven safety during breastfeeding, especially when nursing newborns or preterm infants, may be used.

Hydrochlorothiazide.

Hydrochlorothiazide passes into breast milk in small amounts. High doses of thiazides causing intense diuresis may suppress breast milk production. If its use is absolutely necessary, breastfeeding should be discontinued.

The use of Olspres N during breastfeeding is not recommended. If Olspres N must be used during breastfeeding, the dose should be kept as low as possible.

Ability to affect reaction speed when driving or operating machinery.

Olspres N may have a minor or moderate effect on the ability to drive vehicles or operate machinery. Dizziness and increased fatigue may occasionally occur in patients receiving antihypertensive therapy, which may impair reaction time.

Method of Administration and Dosage

Adults.

Olspres N is not a first-line agent. It is intended for patients in whom treatment with olmesartan medoxomil alone at a dose of 20 mg does not achieve the required level of blood pressure control.

Olspres N tablets should be taken once daily, independently of food intake.

In the presence of clinical indications, transition from monotherapy with olmesartan medoxomil 20 mg directly to the combination drug is permitted; however, it should be noted that the maximum antihypertensive effect of olmesartan medoxomil is achieved after 8 weeks of treatment initiation.

Dose titration of each component is recommended.

Olmesartan medoxomil/hydrochlorothiazide 20/12.5 mg may be prescribed to patients in whom treatment with olmesartan medoxomil alone at a dose of 20 mg does not achieve the required blood pressure control.

Olmesartan medoxomil/hydrochlorothiazide 20/25 mg may be prescribed to patients in whom treatment with olmesartan medoxomil/hydrochlorothiazide 20/12.5 mg does not achieve the required blood pressure control.

Elderly Patients (aged 65 years and older).

The combination drug is recommended for elderly patients at the same dosage as for adult patients.

Renal Impairment.

When Olspres N is administered to patients with mild to moderate renal impairment (creatinine clearance 30–60 mL/min), periodic monitoring of renal function is recommended. Olspres N is contraindicated in patients with severe renal impairment (creatinine clearance < 30 mL/min) (see sections "Contraindications", "Special Warnings and Precautions for Use", "Pharmacological Properties").

Hepatic Impairment.

Olspres N should be used with caution in patients with mild to moderate hepatic impairment. In patients with moderate hepatic impairment, olmesartan medoxomil should be initiated at a dose of 10 mg once daily, and the maximum dose should not exceed 20 mg once daily. Patients with hepatic impairment who are already receiving diuretics and/or other antihypertensive agents should be closely monitored for blood pressure and renal function. Experience with olmesartan medoxomil in patients with severe hepatic impairment is lacking. Olspres N is contraindicated in patients with severe hepatic impairment, as well as in those with cholestasis or biliary obstruction (see sections "Contraindications", "Pharmacological Properties").

Method of Administration.

Tablets should be swallowed whole with sufficient fluid (e.g., a glass of water). Tablets should not be chewed. The drug should be taken daily at the same time.

Children.

The safety and efficacy of Olspres N in children (under 18 years of age) have not been established. Data are lacking.

Overdose.

Specific information regarding symptoms or treatment of Olspres N overdose is lacking.

Close monitoring of the patient and symptomatic supportive treatment are required. Treatment is symptomatic and depends on the time elapsed since drug ingestion and the severity of symptoms. Emetics and/or gastric lavage may be recommended. Activated charcoal may sometimes be recommended in the management of overdose. Serum electrolyte and creatinine levels should be monitored regularly. In case of arterial hypotension, the patient should be placed in a supine position and promptly administered intravenous infusion of isotonic sodium chloride solution.

The most likely manifestations of olmesartan medoxomil overdose are arterial hypotension and tachycardia; bradycardia may also occur. Hydrochlorothiazide overdose is associated with electrolyte disturbances (hypokalemia, hypochloremia) and dehydration due to excessive diuresis. The most common symptoms of overdose are nausea and drowsiness. Hypokalemia may cause muscle cramps and/or exacerbate arrhythmias induced by concomitant medications (cardiac glycosides or certain antiarrhythmics).

It is unknown whether olmesartan or hydrochlorothiazide is removed by hemodialysis.

Adverse reactions.

The most common adverse reactions associated with the use of the drug are headache, dizziness, and increased fatigue.

Hydrochlorothiazide may cause or exacerbate hypovolemia, which may lead to disturbances in electrolyte balance.

The following terminology was used to classify the frequency of adverse reactions: very common (≥1/10), common (≥1/100, <1/10), uncommon (≥1/1000, <1/100), rare (≥1/10000, <1/1000), very rare (<1/10000), not known (cannot be estimated from the available data).

*During the post-marketing period, cases of autoimmune hepatitis with a latency period of several months to years have been reported, which were reversible after discontinuation of olmesartan.

There have been reports of isolated cases of rhabdomyolysis temporally associated with the use of angiotensin II receptor blockers.

The following adverse reactions have been reported with hydrochlorothiazide: dry mouth, thirst, anaphylactic shock, coma, Stevens–Johnson syndrome, disorientation, mood changes, pneumonitis. The use of thiazide diuretics may lead to decreased glucose tolerance, which in turn may result in the manifestation of latent diabetes mellitus. Hypochloremic alkalosis may occur during hydrochlorothiazide therapy, which may trigger gout attacks in patients with asymptomatic gout.

Reporting suspected adverse reactions

Reporting of suspected adverse reactions after drug authorization is of great importance. It allows continuous monitoring of the benefit-risk ratio of the drug. Healthcare professionals, pharmacists, as well as patients or their legal representatives should report all suspected adverse reactions and lack of drug efficacy via the automated pharmacovigilance information system at: https://aisf.dec.gov.ua.
