Pharmacological properties.
Captopres 12.5-Darnitsia is a combined antihypertensive medicinal product containing a fixed-dose combination of captopril and hydrochlorothiazide.
Captopril is an angiotensin-converting enzyme (ACE) inhibitor. It suppresses the formation of angiotensin II, thereby counteracting its vasoconstrictive effects and stimulatory influence on aldosterone secretion in the adrenal glands. It reduces total peripheral vascular resistance and arterial pressure, decreases myocardial preload, and lowers pressure in the right atrium and pulmonary circulation.
Hydrochlorothiazide produces a moderately pronounced diuretic effect by increasing the excretion from the body of sodium, chloride, potassium ions, and water. It reduces sodium ion content in vascular walls, thereby decreasing their sensitivity to vasoconstrictive stimuli and enhancing the antihypertensive effect of captopril.
Pharmacokinetics.
After oral administration, captopril is actively absorbed in the gastrointestinal tract. Time to reach maximum plasma concentration is approximately 1 hour. Plasma protein binding of captopril is 25–30%. It is metabolized in the liver. The main metabolites are captopril-cysteine and the disulfide dimer of captopril. Elimination half-life (T½) is approximately 2–3 hours. 95% of captopril is excreted by the kidneys: 50% as metabolites and up to 50% unchanged.
After oral administration, hydrochlorothiazide is absorbed in the gastrointestinal tract by 68–78%. Its elimination half-life (T½) is approximately 3–4 hours. 20–75% of hydrochlorothiazide is excreted unchanged by the kidneys.
In patients with renal insufficiency, drug elimination is slowed.

Interaction with other medicinal products and other forms of interaction.
Concomitant use of this medicinal product with the following drugs may result in:
with diuretics (thiazide or loop diuretics) – risk of arterial hypotension due to dehydration caused by high-dose diuretic therapy. The hypotensive effect can be minimized by discontinuing diuretics, increasing fluid and salt intake, and reducing initial doses of captopril;
with α- and β-adrenergic blockers, calcium channel blockers with prolonged action, and other antihypertensive agents, organic nitrates, MAO inhibitors, hypnotics (nitrazepam), tranquilizers (alprazolam) – enhanced hypotensive effect of the medicinal product; such combinations should be used with caution;
with ethanol-containing medicinal products and beverages, barbiturates, narcotics, neuroleptics, tricyclic antidepressants – enhanced hypotensive effect and orthostatic hypotension;
with sympathomimetics, estrogens, methenamine – reduced antihypertensive effect of the medicinal product; careful monitoring of blood pressure is required;
with nonsteroidal anti-inflammatory drugs (NSAIDs) – reduced antihypertensive effect and impaired renal function with increased plasma potassium concentration; rarely, acute renal failure may develop, especially in patients with pre-existing renal impairment. Such combinations should be used cautiously. Before initiating treatment, fluid and electrolyte balance should be normalized, and renal function should be monitored periodically during therapy. High-dose salicylates may have their central nervous system toxicity potentiated by hydrochlorothiazide;
with drugs that increase serum potassium concentration (heparin, cyclosporine, potassium-sparing diuretics – amiloride, spironolactone, triamterene), potassium-containing preparations and supplements – marked increase in plasma potassium concentration; concomitant use of these drugs is not recommended. If co-administration is necessary due to existing hypokalemia, it should be done with great caution and frequent monitoring of serum potassium levels;
with allopurinol, procainamide, immunosuppressants (azathioprine), and cytostatic agents – suppression of hematopoiesis;
with diazoxide – enhanced hyperglycemic, hyperuricemic, and hypotensive effects; periodic monitoring of blood glucose and uric acid levels may be required;
with anesthetics, non-depolarizing muscle relaxants, anesthetic induction agents (tubocurarine chloride, gallamine triethiodide) – enhanced effects of the aforementioned drugs; dose adjustment and correction of fluid and electrolyte balance may be necessary before surgery;
with lithium preparations, calcium salts – enhanced effects of the aforementioned drugs; concomitant use is not recommended. Concomitant use of ACE inhibitors and lithium may lead to transient elevation of serum lithium levels and lithium intoxication. Combined use of ACE inhibitors and thiazide diuretics may further increase serum lithium levels and raise the risk of lithium intoxication. Therefore, concomitant use of captopril with lithium is not recommended. If such combination is necessary, careful monitoring of serum lithium levels is required;
with cardiac glycosides – increased toxicity of digitalis preparations (arrhythmias) due to hypokalemia induced by hydrochlorothiazide;
with carbamazepine – increased risk of hyponatremia; periodic monitoring of electrolyte levels may be required;
with amphotericin B, carbenoxolone, glucocorticoids, corticotropin, stimulant laxatives – enhanced electrolyte imbalance, particularly development of hypokalemia;
with metformin – metabolic acidosis in patients with impaired renal function;
with methyldopa – hemolytic anemia in isolated cases;
with antidiabetic agents, oral anticoagulants, drugs for the treatment of gout – reduced efficacy of the aforementioned drugs; dose adjustment may be required;
with medicinal products whose effects are influenced by changes in plasma potassium levels, including:
- class I A antiarrhythmic agents (quinidine, hydroquinidine, disopyramide), class III (amiodarone, sotalol, dofetilide, ibutilide);
- neuroleptics (thioridazine, chlorpromazine, levomepromazine, trifluoperazine, ciomemazine, sulpiride, sultopride, amisulpride, tiapride, pimozide, haloperidol, droperidol);
- other agents: bepridil, cisapride, difeminal, intravenous erythromycin, halofantrine, ketanserin, mizolastine, pentamidine, sparfloxacin, terfenadine, intravenous vinpocetine – risk of "torsades de pointes" arrhythmia due to possible hypokalemia and hypomagnesemia; periodic monitoring of plasma potassium levels and electrocardiography is required;
with pressor amines (norepinephrine) – treatment with the medicinal product should be discontinued one week before surgery;
with antacids, food, cholestyramine, colestipol – reduced absorption and decreased bioavailability of the medicinal product;
with probenecid – reduced excretion of captopril;
with iodine-containing contrast agents – increased risk of acute renal failure, especially with high-dose administration, due to dehydration caused by hydrochlorothiazide. Fluid status should be normalized before iodine administration.
Cytotoxic agents (e.g., cyclophosphamide, methotrexate). Thiazides may reduce renal excretion of cytotoxic drugs and potentiate their myelosuppressive effect.
Anticholinergic agents (e.g., atropine, biperiden). Due to reduced gastrointestinal motility and delayed gastric emptying, bioavailability of thiazide diuretics may increase.
Cyclosporine. Concomitant use may enhance hyperuricemia and increase the risk of complications such as gout.
Amantadine. Thiazides, including hydrochlorothiazide, may increase the risk of adverse effects associated with amantadine.
Nonsteroidal anti-inflammatory drugs (NSAIDs), including selective cyclooxygenase-2 (COX-2) inhibitors, acetylsalicylic acid >3 g/day, and non-selective NSAIDs. Concomitant use of NSAIDs may reduce the antihypertensive effect of hydrochlorothiazide and enhance its effect on serum potassium levels.
MEDICINAL PRODUCTS whose effects are influenced by changes in serum potassium levels. Periodic monitoring of serum potassium levels and ECG examination are recommended when hydrochlorothiazide is used concomitantly with medicinal products whose effects are influenced by changes in serum potassium levels (e.g., digitalis glycosides and antiarrhythmic agents), and with medicinal products that may cause polymorphic ventricular tachycardia of the "torsades de pointes" type, since hypokalemia is a contributing factor to the development of this arrhythmia.
Clinical trial data have shown that dual blockade of the renin-angiotensin-aldosterone system (RAAS) by combined use of ACE inhibitors, angiotensin II receptor blockers, or aliskiren is associated with a higher incidence of adverse reactions such as hypotension, hyperkalemia, and impaired renal function (including acute renal failure), compared to monotherapy with agents acting on the RAAS.
The medicinal product may cause a positive urine test for ketones.
The medicinal product may be used for the treatment of acute myocardial infarction in combination with acetylsalicylic acid (cardiological doses), thrombolytic agents, β-adrenergic blockers, and/or nitrates.
Special precautions.
Before starting treatment with the medicinal product, diuretic therapy should be reduced or completely discontinued.
Prior to prescribing angiotensin-converting enzyme (ACE) inhibitors, circulating blood volume (CBV) should be corrected, and the issue of selecting the lowest effective optimal dose of the medicinal product should be addressed.
During treatment with the medicinal product, periodic monitoring of electrolyte levels (particularly potassium), plasma urea and creatinine concentrations, and peripheral blood picture is recommended.
A low-sodium diet is recommended during treatment with the medicinal product.
Alcoholic beverages should not be consumed during treatment with the medicinal product.
The medicinal product should be used with caution in patients with disturbances in water-electrolyte balance (due to intensive diuretic therapy, diarrhea, vomiting, or low-sodium diet) and in patients undergoing hemodialysis, as arterial hypotension may develop. Water-electrolyte balance should be corrected before initiating treatment with the medicinal product.
The medicinal product should be used with caution in patients with severe cardiac dysfunction and in elderly patients (aged 65 years and older). Prescribing the medicinal product to these patient groups is possible only under conditions of careful monitoring of arterial pressure, renal function, and water-electrolyte status.
In case of hypotension, the patient should be placed in a horizontal position (lying on the back), and if necessary, CBV should be increased by administration of 0.9% sodium chloride solution.
Special precautions related to the presence of hydrochlorothiazide in the medicinal product.
As with other antihypertensive medicinal products, symptomatic arterial hypotension may occur in some patients.
Treatment with thiazides may reduce glucose tolerance. Adjustment of antidiabetic agents, including insulin, may be required. Latent diabetes mellitus may become manifest during thiazide therapy.
Thiazides may reduce renal excretion of calcium and may cause a slight transient increase in serum calcium levels. Marked hypercalcemia may be a sign of latent hyperparathyroidism.
Patients receiving thiazides may develop hypersensitivity reactions, even in the absence of a history of allergy or bronchial asthma. Cases of exacerbation or activation of systemic lupus erythematosus during thiazide therapy have been reported.
The medicinal product may affect the results of the following laboratory tests:
- The medicinal product may decrease plasma protein-bound iodine levels;
- Treatment with the medicinal product should be discontinued before laboratory evaluation of parathyroid function;
- The medicinal product may increase free bilirubin concentration in serum.
The medicinal product should be used with caution in patients with impaired liver function or progressive liver disease, as thiazide diuretics may disturb water-electrolyte balance, potentially leading to rapid development of hepatic coma. Prescribing the medicinal product to these patients is possible only under careful monitoring of arterial pressure, renal function, and water-electrolyte status.
The medicinal product should be used with caution in patients with impaired renal function, as thiazide diuretics may cause azotemia. Accumulation of the medicinal product is also possible. In progressive renal disease characterized by elevated blood urea nitrogen levels, the necessity of continuing therapy should be carefully evaluated, and treatment should be discontinued if necessary.
The antihypertensive effect of hydrochlorothiazide may be enhanced after sympathectomy.
In patients taking hydrochlorothiazide, gout exacerbation due to increased uric acid concentration, clinical manifestation of latent diabetes mellitus, and exacerbation of systemic lupus erythematosus may occur.
Cases of photosensitivity reactions have been reported during treatment with thiazide diuretics. If photosensitivity reactions occur during treatment with the medicinal product, it is recommended to discontinue the drug. If the physician considers reinitiating diuretic therapy necessary, protection of skin areas exposed to sunlight or artificial UV radiation is recommended.
Hydrochlorothiazide may cause water-electrolyte imbalance (hypokalemia, hyponatremia, and hypochloremic alkalosis). Symptoms include dry mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pain or cramps, muscle weakness, arterial hypotension, oliguria, tachycardia, and gastrointestinal disturbances such as nausea and vomiting. Although concomitant use with captopril reduces the risk of hydrochlorothiazide-induced hypokalemia, patients at high risk of developing hypokalemia include those with liver cirrhosis, high diuresis, inadequate oral electrolyte replacement, and those receiving glucocorticoid therapy or adrenocorticotropic hormone. In hot weather, hyponatremia, usually mild and not requiring treatment, may occur in patients prone to edema.
Hydrochlorothiazide may cause hypercalcemia. Therefore, the use of the medicinal product should be discontinued before assessing parathyroid function.
Hydrochlorothiazide may increase cholesterol and triglyceride levels, decrease serum magnesium and iodine-binding thyroglobulins (without signs of thyroid dysfunction).
Hydrochlorothiazide may cause a positive doping test.
Hydrochlorothiazide may cause acute respiratory toxicity, including acute respiratory distress syndrome (ARDS). Very rare severe cases of acute respiratory toxicity, including ARDS, have been reported after hydrochlorothiazide administration. Pulmonary edema usually develops within minutes or hours after taking hydrochlorothiazide. Initial symptoms include dyspnea, fever, worsening lung condition, and hypotension. If ARDS is suspected, hydrochlorothiazide should be discontinued and appropriate treatment initiated. Hydrochlorothiazide should not be prescribed to patients who previously experienced ARDS after taking hydrochlorothiazide.
Choroidal effusion, acute myopia, and secondary angle-closure glaucoma
Medicinal products containing hydrochlorothiazide, a sulfonamide derivative, may cause an idiosyncratic reaction leading to choroidal effusion with visual field defects, transient myopia, and acute angle-closure glaucoma. Symptoms include sudden onset of decreased visual acuity or eye pain and usually occur within hours or weeks of starting treatment.
Untreated acute angle-closure glaucoma may lead to permanent vision loss. The primary treatment is prompt discontinuation of the medicinal product. If intraocular pressure remains uncontrolled, medical or surgical interventions may be necessary. Risk factors for developing acute angle-closure glaucoma may include a history of sulfonamide or penicillin allergy.
Special precautions related to the presence of captopril in the medicinal product.
The medicinal product should be used with caution in patients with impaired renal function (creatinine clearance less than 40 mL/min). Initial doses of captopril should be adjusted according to creatinine clearance and subsequently based on the patient's response to treatment. Regular monitoring of renal function parameters (at the beginning and periodically during treatment) is required: plasma potassium and creatinine levels should be determined.
The medicinal product should be used with caution in patients with uncomplicated arterial hypertension, as symptomatic arterial hypotension may occur in individual cases. The likelihood of its development increases in patients with water-electrolyte imbalance (due to intensive diuretic therapy, diarrhea, vomiting, low-sodium diet) and in patients undergoing hemodialysis. Symptomatic hypotension has also been observed in patients with heart failure. Treatment of such patients should be initiated under medical supervision with low doses, carefully titrated. This also applies to patients with ischemic heart disease or cerebrovascular disease, in whom significant reduction in arterial pressure may lead to myocardial infarction or impaired cerebral circulation (stroke).
Captopril intake should be avoided in cases of cardiogenic shock and significant hemodynamic disturbances.
The medicinal product should be used with caution in patients with renovascular hypertension, as concomitant use with ACE inhibitors increases the risk of severe arterial hypotension and renal failure. Treatment of such patients should be initiated under medical supervision with low doses, carefully titrated.
It is evident that combined use of ACE inhibitors, angiotensin II receptor blockers, or aliskiren increases the risk of hypotension, hyperkalemia, and impaired renal function (including acute renal failure). Therefore, dual blockade of the renin-angiotensin-aldosterone system (RAAS) by combining ACE inhibitors, angiotensin II receptor blockers, or aliskiren is not recommended.
If dual blockade therapy is absolutely necessary, it should be conducted under medical supervision with frequent monitoring of renal function, electrolytes, and arterial pressure.
Concomitant use of ACE inhibitors and angiotensin II receptor blockers is not recommended in patients with diabetic nephropathy.
The medicinal product should be used with caution in diabetic patients receiving oral antidiabetic agents or insulin, with regular monitoring of blood glucose levels, especially during the first month of treatment.
Very rarely, ACE inhibitor use has been associated with a syndrome beginning with cholestatic jaundice and rapidly progressing to liver necrosis and (sometimes) resulting in fatal outcome. The mechanism of this syndrome is not established. Patients receiving ACE inhibitors who develop jaundice or marked elevation of liver enzymes should discontinue ACE inhibitors and consult a physician.
Proteinuria may occur in patients, particularly those receiving relatively high doses of captopril (more than 150 mg/day) or with impaired renal function. Protein content in urine exceeding 1 g/day was recorded in approximately 0.7% of patients receiving captopril. Nephrotic syndrome was diagnosed in 20% of patients with proteinuria. In most cases, proteinuria resolved within 6 months after discontinuation of the medicinal product. Renal function parameters, such as blood urea nitrogen and creatinine levels, rarely changed. In patients with impaired renal function, urine protein content should be determined before treatment and monitored periodically during therapy.
Cases of neutropenia, agranulocytosis, thrombocytopenia, and anemia have been reported in patients taking ACE inhibitors. Neutropenia is rare in patients with normal renal function and no other risk factors. Extreme caution is required when prescribing the medicinal product to patients with collagenoses, those undergoing immunosuppressive therapy, patients taking allopurinol or procainamide, and in cases combining these conditions, especially with existing renal impairment. Severe infections, not always responsive to intensive antibiotic therapy, may develop in some such patients. Periodic monitoring of white blood cell count and differential blood count (before treatment, every 2 weeks during the first 3 months of therapy, and periodically thereafter) is recommended in such patients, and patients should be warned to report any signs of infection (fever, lymph node enlargement, sore throat). If neutropenia develops (neutrophil count < 1000/mm³), the medicinal product should be discontinued. In most patients, neutrophil count returns rapidly to normal after stopping therapy.
In some patients taking ACE inhibitors, including captopril, increased serum potassium levels have been observed. Patients at risk of hyperkalemia include those with renal failure, diabetes mellitus, those taking potassium-sparing diuretics, potassium supplements, and patients taking other medicinal products that increase serum potassium levels. If concomitant use of these medicinal products during ACE inhibitor therapy is necessary, regular monitoring of serum potassium levels is required.
Cases of angioedema of the face, extremities, lips, tongue, glottis, and larynx have been reported in some patients taking ACE inhibitors, particularly during the first weeks of treatment. In individual cases, angioedema may develop even after prolonged ACE inhibitor therapy. Isolated fatal cases due to laryngeal or tongue angioedema have been reported. If angioedema develops, captopril intake should be immediately discontinued and appropriate treatment initiated. The patient should be hospitalized and monitored for at least 12–24 hours until symptoms completely resolve. Patients of non-Caucasian race are at higher risk of developing angioedema.
In patients undergoing surgery or anesthesia with agents that lower arterial pressure, captopril may block the compensatory renin release-induced increase in angiotensin II formation. Arterial hypotension resulting from this mechanism should be corrected by administration of additional fluid volume.
A persistent, non-productive cough may occur in patients during treatment with ACE inhibitors, which resolves after discontinuation of therapy.
In patients taking ACE inhibitors undergoing allergen desensitization with Hymenoptera venom, anaphylactoid reactions may occur. These reactions can be avoided by temporarily discontinuing ACE inhibitor therapy.
In patients taking ACE inhibitors undergoing hemodialysis with high-flux membranes, anaphylactoid reactions may occur. These reactions can be avoided by replacing dialysis membranes with another type or by using antihypertensive agents of another class.
In patients taking ACE inhibitors undergoing LDL apheresis, anaphylactoid reactions may occur. These reactions can be avoided by temporarily discontinuing ACE inhibitor therapy before each apheresis.
Cross-sensitivity is possible with medicinal products containing ACE inhibitors.
ACE inhibitors, including captopril, are less effective in reducing arterial pressure in patients of non-Caucasian race compared to patients of other races, due to predominant low renin fractions.
Concomitant use of the medicinal product with lithium is not recommended due to increased lithium toxicity.
The medicinal product contains lactose; therefore, it should not be administered to patients with rare hereditary forms of galactose intolerance, lactase deficiency, or glucose-galactose malabsorption syndrome.
Use during pregnancy or breastfeeding.
The medicinal product is contraindicated in pregnant women or women planning to become pregnant. If pregnancy is confirmed during treatment with the medicinal product, its use should be immediately discontinued and replaced with another medicinal product approved for use during pregnancy.
The medicinal product should not be used during breastfeeding.
Ability to affect reaction speed when driving vehicles or operating machinery.
When using the medicinal product, patients should refrain from driving vehicles or operating machinery, as dizziness and drowsiness may occur, especially at the beginning of therapy.
Administration and Dosage.
The medicinal product is taken orally, 1 hour before meals, since the presence of food in the stomach reduces drug absorption.
The dosage is individually determined by a physician depending on the clinical presentation of the disease.
The initial dose may be ½ tablet (25 mg captopril and 6.25 mg hydrochlorothiazide) once daily.
If necessary, the maintenance dose may subsequently be increased to 1 tablet (50 mg captopril and 12.5 mg hydrochlorothiazide) once daily.
Maximum therapeutic effect is achieved within 6–8 weeks after initiation of treatment. Dose adjustments should be made at 6-week intervals, unless clinical manifestations require more rapid changes. If blood pressure reduction is insufficient, captopril and hydrochlorothiazide may be added to the treatment regimen as individual monopreparations. In such cases, the daily dose of captopril should not exceed 150 mg and that of hydrochlorothiazide should not exceed 50 mg.
Patients with renal impairment.
Since captopril and hydrochlorothiazide are primarily eliminated via the kidneys, their plasma levels may increase in patients with impaired renal function. Dose reduction is recommended: for creatinine clearance between 30 and 80 mL/min, the initial dose is ½ tablet (25 mg captopril and 6.25 mg hydrochlorothiazide) once daily in the morning.
Children.
There are no data on the use of this medicinal product in children.
Overdose.
Captopril.
Symptoms: severe hypotension, tachycardia, headache, loss of appetite, taste disturbances, skin allergic reactions, neutropenia. In severe cases, seizures, paralysis, shock, stupor, cardiac arrhythmias, bradycardia, renal failure, and electrolyte imbalance may occur. If these symptoms appear, the drug should be discontinued immediately and medical advice should be sought.
Treatment: the patient should be placed in a horizontal position and gastric lavage should be performed.
In cases of severe overdose, the patient must be urgently hospitalized for intensive detoxification methods, including hemodialysis, and for measures aimed at increasing circulating blood volume and normalizing the functions of the cardiovascular, respiratory, and nervous systems, as well as restoring kidney function. Hemodialysis using high-flux membranes made of polyacrylonitrile-metalsulfonate (AN69) and hemofiltration should be avoided due to the risk of anaphylactoid reactions. Peritoneal dialysis is ineffective.
Symptomatic therapy should be administered to normalize blood pressure and relieve other symptoms.
Hydrochlorothiazide.
Symptoms: weakness, nausea, vomiting, thirst, diarrhea. These symptoms usually resolve quickly upon dose reduction or discontinuation of the drug. In some cases, following ingestion of high doses, the following symptoms have been reported: tachycardia, arterial hypotension, shock, dizziness, confusion, disturbances of consciousness, muscle cramps, paresthesia, exhaustion, polyuria, oliguria, anuria, hypokalemia, hyponatremia, hypochloremia, alkalosis, increased blood urea nitrogen levels (in patients with renal insufficiency). Severe manifestations of overdose may include severe disturbances of water-electrolyte balance and development of coma due to the direct pathological effect of hydrochlorothiazide on the central nervous system.
Treatment: to remove the drug from the stomach, induction of emesis is recommended, followed by gastric lavage and administration of adsorbents. In cases of severe overdose manifestations, the patient must be immediately hospitalized in a specialized medical facility for intensive detoxification procedures (including hemodialysis), correction of water-electrolyte imbalances, normalization of cardiovascular, respiratory, and central nervous system functions, and restoration of kidney function.
