Pharmacological Properties

Pharmacodynamics

Dexketoprofen trometamol is a propionic acid salt that exerts analgesic, anti-inflammatory, and antipyretic effects and belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs).

The mechanism of action of NSAIDs is based on reducing the synthesis of prostaglandins by inhibiting cyclooxygenase activity. Specifically, the conversion of arachidonic acid into cyclic endoperoxides PGG2 and PGH2 is inhibited, from which prostaglandins PGE1, PGE2, PGF2α, PGD2, as well as prostacyclin PGI2 and thromboxanes TxА2 and TxВ2 are formed. In addition, inhibition of prostaglandin synthesis may affect other mediators of inflammation such as kinins, which may also indirectly influence the primary action of dexketoprofen. Inhibitory effects on the activity of both cyclooxygenase-1 and cyclooxygenase-2 have been demonstrated in laboratory animals and in humans.

Clinical studies in various types of pain have demonstrated that dexketoprofen has pronounced analgesic activity. Its analgesic effect after intramuscular and intravenous administration in patients with moderate to severe pain has been studied in various pain conditions associated with surgical procedures (orthopedic and gynecological surgeries, abdominal surgeries), as well as musculoskeletal pain (acute low back pain) and renal colic. In these studies, the analgesic effect began rapidly and reached its maximum within the first 45 minutes. The duration of analgesic action after administration of 50 mg of dexketoprofen is typically 8 hours. The use of dexketoprofen allows a significant reduction in opioid dosage when used concomitantly to manage postoperative pain. Patients who received morphine (via a patient-controlled analgesia device) along with dexketoprofen required significantly less morphine (by 30–45%) compared to patients who received placebo.

Pharmacokinetics

Absorption

After intramuscular administration of dexketoprofen, maximum plasma concentration (Cmax) is reached in approximately 20 minutes (10–45 minutes). It has been demonstrated that after single intramuscular or intravenous administration of 25–50 mg, the area under the concentration-time curve (AUC) is dose-proportional. Multiple-dose pharmacokinetic studies have shown that AUC and Cmax (mean maximum value) after the last intramuscular or intravenous dose do not differ from those after single administration, indicating no accumulation of dexketoprofen.

Distribution

Similar to other drugs with a high degree of plasma protein binding (99%), the volume of distribution of dexketoprofen averages 0.25 L/kg. The distribution half-life is approximately 0.35 hours.

Metabolism

The metabolism of dexketoprofen occurs mainly via conjugation with glucuronic acid, followed by renal excretion. After administration, only the S-(+) optical isomer is detected in urine, indicating the absence of interconversion of the drug into the R-(-) optical isomer in humans.

Elimination

The elimination half-life (T1/2) of dexketoprofen is 1–2.7 hours.

Elderly Patients

After administration of single and multiple doses, the extent of exposure to dexketoprofen in healthy elderly volunteers (aged 65 years and older) participating in the study was significantly higher (up to 55%) compared to younger volunteers; however, no statistically significant differences in maximum concentration (Cmax) or time to reach Cmax (tmax) were observed. The mean T1/2 was prolonged (by up to 48%), and the total systemic clearance was reduced.

Clinical characteristics.

Indications.

Symptomatic treatment of moderate to severe acute pain when oral administration of dexketoprofen is inappropriate, for example, in postoperative pain, renal colic, and low back pain.

Interaction with other medicinal products and other forms of interaction.

Concomitant use of dexketoprofen with the following agents is not recommended.

Other NSAIDs (including selective cyclooxygenase-2 inhibitors), including salicylates in high doses (≥ 3 g/day): concomitant use of dexketoprofen with these agents increases the risk of gastrointestinal ulceration and gastrointestinal bleeding due to their mutually enhancing effects.
Anticoagulants: concomitant use with dexketoprofen enhances the effect of anticoagulants, e.g., warfarin (due to high plasma protein binding of dexketoprofen, inhibition of platelet function, and damage to gastric and duodenal mucosa). If concomitant use is necessary, careful physician monitoring and laboratory parameter surveillance are required.
Heparins: concomitant use of dexketoprofen with these agents increases the risk of bleeding (due to inhibition of platelet function and damage to gastric and duodenal mucosa by dexketoprofen). If concomitant use is necessary, careful physician monitoring and laboratory parameter surveillance are required.
Corticosteroids: concomitant use of dexketoprofen with these agents increases the risk of gastrointestinal ulceration or gastrointestinal bleeding.
Lithium: concomitant use with NSAIDs (reports exist for several NSAIDs) increases lithium plasma levels, potentially leading to toxicity (reduced renal excretion of lithium). Lithium plasma levels should be monitored at the beginning of dexketoprofen therapy, during dose adjustment, or upon discontinuation.
High-dose methotrexate (≥ 15 mg/week): concomitant use with dexketoprofen reduces renal clearance of methotrexate and generally enhances its adverse effects on the blood system.
Hydantoin derivatives and sulfonamides: concomitant use with dexketoprofen enhances the toxicity of these agents.

Concomitant use of dexketoprofen with the following agents should be performed with caution.

Diuretics, angiotensin-converting enzyme (ACE) inhibitors, aminoglycoside antibiotics, and angiotensin II receptor antagonists: concomitant use with dexketoprofen may reduce the efficacy of diuretics and other antihypertensive agents. In some patients with impaired renal function (e.g., dehydration or elderly patients), concomitant use of cyclooxygenase inhibitors (including dexketoprofen) with ACE inhibitors, angiotensin II receptor antagonists, or aminoglycoside antibiotics may worsen renal function, which is usually reversible. When using these agents together, ensure the patient is not dehydrated and monitor renal function at the beginning of treatment.
Low-dose methotrexate (< 15 mg/week): concomitant use with dexketoprofen reduces renal clearance of methotrexate and generally enhances its adverse effects on the blood system. Blood tests should be performed weekly during the first weeks of concomitant use. Close medical monitoring is required for patients with even mild renal impairment and in elderly patients.
Pentoxifylline: concomitant use of dexketoprofen with pentoxifylline carries a risk of bleeding. Enhanced monitoring and more frequent assessment of bleeding time are recommended.
Zidovudine: concomitant use of dexketoprofen with zidovudine may increase toxic effects on erythrocytes due to effects on reticulocytes, leading to severe anemia after the first week of NSAID use. Blood tests and reticulocyte counts should be performed after 1–2 weeks of concomitant use.
Sulfonylurea preparations: concomitant use with dexketoprofen enhances the hypoglycemic effect of these agents due to displacement of sulfonylureas from plasma protein binding sites.

When using dexketoprofen concomitantly with the following agents, potential interactions should be considered.

Beta-blockers: concomitant use with dexketoprofen may reduce the antihypertensive effect of beta-blockers (due to inhibition of prostaglandin synthesis).
Cyclosporine, tacrolimus: concomitant use with dexketoprofen may increase the nephrotoxicity of these agents (due to the effect of dexketoprofen on renal prostaglandins). Renal function should be monitored when these agents are used together.
Thrombolytic agents: concomitant use of dexketoprofen with these agents increases the risk of bleeding.
Antiplatelet agents and selective serotonin reuptake inhibitors (SSRIs): concomitant use of dexketoprofen with these agents increases the risk of gastrointestinal bleeding.
Probenecid: concomitant use with probenecid may increase plasma levels of dexketoprofen, likely due to inhibition of its renal tubular secretion and glucuronic acid conjugation. Dose adjustment of dexketoprofen may be necessary.
Cardiac glycosides: concomitant use with dexketoprofen may increase plasma levels of glycosides.
Mifepristone: theoretically, there is a risk of altered mifepristone efficacy due to prostaglandin synthetase inhibitors. Limited data suggest that concomitant use of NSAIDs on the same day as prostaglandin does not adversely affect mifepristone or prostaglandin efficacy regarding cervical ripening or contractility, nor does it reduce the clinical efficacy of drugs for medical termination of pregnancy.
Quinolone antibiotics: animal studies indicate that concomitant use of high-dose quinolones with NSAIDs increases the risk of seizures.
Tenofovir: concomitant use with dexketoprofen may increase blood urea nitrogen and creatinine levels. Renal function should be monitored when these agents are used together.
Deferasirox: concomitant use of dexketoprofen with deferasirox may increase the risk of gastrointestinal toxicity. Close patient monitoring is required.
Pemetrexed: concomitant use with dexketoprofen may reduce pemetrexed elimination. Particular caution is required when using these agents together (especially with high-dose dexketoprofen). In patients with mild to moderate renal impairment (creatinine clearance 45–79 mL/min), concomitant use of pemetrexed and dexketoprofen should be avoided for 2 days before and 2 days after pemetrexed administration.

Special precautions for use.

The medicinal product should be used with caution in patients with a history of allergic conditions.

Concomitant use of the medicinal product with other NSAIDs, including selective cyclooxygenase-2 inhibitors, should be avoided.

Adverse reactions of the medicinal product can be minimized by using the lowest effective dose for the shortest duration necessary to control symptoms.

Gastrointestinal safety

Gastrointestinal bleeding, ulceration, or perforation, in some cases fatal, have been reported with NSAIDs at any stage of treatment, regardless of the presence of warning symptoms or a history of serious gastrointestinal disorders.

If gastrointestinal bleeding or ulceration occurs, the medicinal product should be discontinued.

The risk of gastrointestinal bleeding, ulceration, or perforation increases with higher NSAID doses, in patients with a history of peptic ulcer, particularly if complicated by bleeding or perforation, and in elderly patients.

Elderly patients: elderly patients have an increased frequency of adverse reactions to NSAIDs, especially gastrointestinal bleeding and perforation, sometimes fatal. Treatment of such patients should be initiated with the lowest possible dose.

As with all NSAIDs, patients with a history of esophagitis, gastritis, and/or peptic ulcer should be ensured to be in remission before initiating treatment.

Patients with existing gastrointestinal symptoms or a history of gastrointestinal disorders should be monitored for possible gastrointestinal disturbances during treatment, particularly gastrointestinal bleeding.

NSAIDs should be used with caution in patients with a history of gastrointestinal disorders (ulcerative colitis, Crohn's disease), as there is a risk of exacerbation. For such patients and patients taking low-dose acetylsalicylic acid or other agents increasing the risk of gastrointestinal adverse reactions, concomitant therapy with protective agents such as misoprostol or proton pump inhibitors should be considered.

Patients, especially elderly, with a history of gastrointestinal adverse reactions should be advised to inform their physician about any unusual gastrointestinal symptoms, including gastrointestinal bleeding, particularly during the initial stages of treatment.

The medicinal product should be prescribed with caution to patients who are concurrently using agents that may increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants (e.g., warfarin), selective serotonin reuptake inhibitors, or antiplatelet agents such as acetylsalicylic acid.

Renal safety

The medicinal product should be used with caution in patients with impaired renal function, as NSAIDs may cause deterioration of renal function, fluid retention, and edema. Due to the increased risk of nephrotoxicity, the medicinal product should be used with caution in patients concurrently taking diuretics and in patients at risk of developing hypovolemia.

During treatment with the medicinal product, adequate fluid intake should be maintained to prevent dehydration, which may increase nephrotoxic effects.

Like other NSAIDs, dexketoprofen may increase plasma concentrations of blood urea nitrogen and creatinine.

Similar to other inhibitors of prostaglandin synthesis, its use may be associated with renal adverse reactions leading to glomerulonephritis, interstitial nephritis, papillary necrosis, nephrotic syndrome, and acute renal failure. Renal function disturbances occur most frequently in elderly patients.

Hepatic effects

The medicinal product should be used with caution in patients with impaired liver function. Like other NSAIDs, dexketoprofen may cause transient and minor elevations in some liver function parameters, as well as marked increases in AST and ALT activity. If such elevations occur, the use of the medicinal product should be discontinued.

Hepatic function disturbances occur most frequently in elderly patients.

Cardiovascular and cerebrovascular safety

Patients with hypertension and/or mild to moderate heart failure require monitoring and medical advice. The medicinal product should be used with particular caution in patients with a history of heart disease, particularly previous episodes of heart failure (as dexketoprofen may increase the risk of heart failure), due to the potential for fluid retention and edema during NSAID therapy. Clinical studies and epidemiological data suggest that some NSAIDs (especially at high doses and prolonged use) may slightly increase the risk of arterial thrombotic events (e.g., myocardial infarction or stroke). Data to exclude such risk with dexketoprofen use are insufficient.

The medicinal product may be used only after careful assessment in patients with uncontrolled hypertension, congestive heart failure, ischemic heart disease, peripheral arterial disease, and/or cerebrovascular disease. A similarly careful assessment should be performed before initiating long-term treatment in patients with risk factors for cardiovascular disease (such as hypertension, hyperlipidemia, diabetes, smoking).

Non-selective NSAIDs can reduce platelet aggregation and prolong bleeding time by inhibiting prostaglandin synthesis. Concomitant use of dexketoprofen and low-molecular-weight heparin at prophylactic doses in the postoperative period has been studied in clinical trials, and no effect on coagulation parameters was observed.

However, patients taking agents affecting hemostasis, such as warfarin, other coumarin derivatives, or heparins, should be under close medical supervision during treatment. Cardiovascular function disturbances occur most frequently in elderly patients.

Skin reactions

Rare cases of serious skin reactions (some fatal), including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have been reported during NSAID use. The highest risk is likely during the initial stages of treatment, with most cases occurring within the first month of therapy. If skin rashes, signs of mucosal involvement, or other symptoms of hypersensitivity occur, the medicinal product should be discontinued.

Masking of symptoms of underlying infections

The medicinal product may mask symptoms of infections, potentially interfering with diagnosis and timely treatment, thereby worsening infection outcomes. Such cases have been observed in bacterial pneumonia and bacterial complications of varicella. When the medicinal product is used to relieve pain associated with an infectious process, monitoring of the infection is recommended. In outpatient settings, patients should consult a physician if symptoms persist or worsen.

Other information.

The medicinal product should be used with particular caution in patients with hereditary porphyrin metabolism disorders (e.g., acute intermittent porphyria), dehydration, or immediately after major surgical procedures.

If prolonged use of dexketoprofen is deemed necessary by the physician, regular monitoring of liver and kidney function is recommended.

During dexketoprofen use, severe acute hypersensitivity reactions (e.g., anaphylactic shock) have been observed very rarely. If early signs of severe hypersensitivity reactions occur, the medicinal product should be discontinued. Depending on symptoms, any necessary treatment should be administered under medical supervision.

Patients suffering from asthma combined with chronic rhinitis, chronic sinusitis, and/or nasal polyps are at higher risk of allergy to acetylsalicylic acid and/or NSAIDs compared to other patients. Use of the medicinal product may trigger asthma attacks or bronchospasm, especially in patients allergic to acetylsalicylic acid or NSAIDs.

Severe infectious complications of the skin and soft tissues may occur during varicella. Data to exclude the role of NSAIDs in exacerbating this infectious process are lacking. Therefore, use of the medicinal product is not recommended during varicella.

The medicinal product should be used with caution in patients with blood disorders, systemic lupus erythematosus, and mixed connective tissue diseases.

Like other NSAIDs, dexketoprofen may mask symptoms of infectious diseases during its use. In isolated cases, activation of infectious processes localized in soft tissues has been reported during NSAID use. If signs of bacterial infection develop or worsen, immediate medical attention is required.

Each ampoule of the medicinal product contains 12.35 vol.% ethanol, i.e., up to 200 mg per dose (equivalent to 5 ml of beer or 2.08 ml of wine per dose). The small amount of alcohol contained in this medicinal product has no significant effect.

The medicinal product contains less than 1 mmol sodium (23 mg) per dose and is therefore considered practically sodium-free.

Use during pregnancy or breastfeeding.

The medicinal product is contraindicated during the third trimester of pregnancy and during breastfeeding.

Pregnancy

Inhibition of prostaglandin synthesis may adversely affect pregnancy and/or fetal development. According to epidemiological studies, use of prostaglandin synthesis inhibitors in early pregnancy increases the risk of miscarriage, congenital heart defects, and abdominal wall defects in the fetus. The absolute risk of cardiovascular abnormalities increases from <1% to approximately 1.5%. The risk is considered to increase with higher doses of dexketoprofen and longer duration of therapy. In animal studies, prostaglandin synthesis inhibitors caused increased pre- and post-implantation losses and increased embryofetal mortality. Furthermore, in animals treated with prostaglandin synthesis inhibitors during organogenesis, increased incidence of fetal developmental abnormalities, including cardiovascular anomalies, was observed. However, animal studies with dexketoprofen trometamol did not reveal toxicity to reproductive organs.

From the 20th week of pregnancy, dexketoprofen use may cause oligohydramnios due to fetal renal dysfunction. This may occur soon after initiation of treatment and is usually reversible upon discontinuation of the medicinal product.

During the first and second trimesters of pregnancy, use of the medicinal product is possible only if absolutely necessary.

When using the medicinal product in women planning pregnancy or during the first and second trimesters of pregnancy, the lowest effective dose for the shortest possible duration should be used.

Fetal monitoring for oligohydramnios and ductus arteriosus constriction should be considered after several days of dexketoprofen exposure, starting from the 20th gestational week. The medicinal product should be discontinued if oligohydramnios is detected.

During the third trimester of pregnancy, all prostaglandin synthesis inhibitors may cause:

Risks for the fetus:

cardiopulmonary toxic syndrome (with closure of the ductus arteriosus and pulmonary hypertension);
impaired renal function, which may progress to renal failure with oligohydramnios (see above);

Risks for mother and child at the end of pregnancy:

prolonged bleeding time (due to inhibition of platelet aggregation), which may occur even with low-dose use;
delayed uterine contractions, leading to prolonged labor.

Breastfeeding period

There are no data on the passage of dexketoprofen into breast milk. The use of the medicinal product is contraindicated during breastfeeding.

Fertility

Like all other NSAIDs, dexketoprofen may reduce female fertility and therefore is not recommended for women planning pregnancy. Women experiencing fertility problems or undergoing infertility evaluation should consider discontinuing the medicinal product.

Ability to influence reaction speed when driving or operating machinery.

During dexketoprofen use, dizziness, visual disturbances, or somnolence may occur. In such cases, the ability to react quickly, orient in traffic situations, and drive or operate machinery may be impaired.

Method of Administration and Dosage

Dosage

Adults

The recommended dose is 50 mg every 8–12 hours.

If necessary, a repeat dose may be administered after 6 hours.

The maximum daily dose should not exceed 150 mg.

The medicinal product is intended for short-term use and should be administered only during the period of acute pain (no longer than 2 days).

Patients should be switched to oral analgesics as soon as possible, if feasible.

Adverse reactions can be minimized by using the lowest effective dose for the shortest duration necessary to control symptoms.

For moderate to severe postoperative pain, the medicinal product may be used as indicated at the same recommended doses in combination with opioid analgesics.

Elderly Patients

Dose adjustment is generally not required in elderly patients. However, due to physiological decline in renal function, a lower dose is recommended: the maximum daily dose should be limited to 50 mg in patients with mild renal impairment.

Patients with Renal Impairment

In patients with mild renal impairment (creatinine clearance 60–89 mL/min), the maximum daily dose should be reduced to 50 mg. The use of the medicinal product is contraindicated in patients with moderate or severe renal impairment (creatinine clearance <59 mL/min).

Patients with Hepatic Impairment

In patients with mild to moderate hepatic impairment (Child–Pugh score 5–9), the maximum daily dose should be reduced to 50 mg, and liver function should be closely monitored. The use of the medicinal product is contraindicated in patients with severe hepatic impairment (Child–Pugh score 10–15).
