Pharmacotherapeutic group: nonsteroidal anti-inflammatory drug (NSAID)

ATC code: M01AE17

Pharmacological properties

Pharmacodynamics

Dexketoprofen trometamol refers to non-steroidal anti-inflammatory drugs (NSAIDs) with analgesic, anti-inflammatory and antipyretic effects. The mechanism of action of dexketoprofen is based on inhibition of prostaglandin synthesis at the level of cyclooxygenases (COX-1 and COX-2).

The analgesic effect comes within 30 min after oral administration, the duration of therapeutic effect is 4-6 h.

Pharmacokinetics

Absorption. Time of reaching maximum concentration (ÒCmax) of dexketoprofen in blood plasma after a single oral single dose is on average 30 min (15-60 min). Simultaneous intake of food slows down absorption of dexketoprofen.

The areas under the curve “concentration-time” (AUC) after single and repeated doses are similar, indicating that there is no cumulation of the drug.

Distribution. Dexketoprofen is characterized by high degree of binding to blood plasma proteins (99 %). Mean volume of distribution (Vd) is less than 0.25 l/kg, the period of half-distribution is about 0.35 h.

Metabolism and excretion. The main way of dexketoprofen metabolism is its conjugation with glucuronic acid with subsequent excretion by the kidneys. The elimination half-life (T1/2) of dexketoprofen is 1.65 hours. In elderly patients the elimination half-life is prolonged up to 48 % and total clearance of the drug decreases.

Indications

Musculoskeletal pain (mild or moderate), algodismenorrhea, toothache.

The drug is intended for symptomatic treatment, reducing pain and inflammation at the time of use.

Pharmacological properties

Pharmacodynamics

Dexketoprofen trometamol is a non-steroidal anti-inflammatory drug (NSAID) and has analgesic, anti-inflammatory and antipyretic effects. The mechanism of action of dexketoprofen is based on inhibition of prostaglandin synthesis at the level of cyclooxygenases (COX-1 and COX-2).

The analgesic effect occurs 30 minutes after taking the drug orally, the duration of the therapeutic effect is 4-6 hours.

Pharmacokinetics

Suction. The time to reach the maximum concentration (TCmax) of dexketoprofen in the blood plasma after a single oral dose averages 30 minutes (15-60 minutes). Concomitant food intake slows down the absorption of dexketoprofen.

The areas under the concentration-time curve (AUC) after single and repeated doses are similar, indicating the absence of drug accumulation.

Distribution. Dexketoprofen is characterized by a high degree of binding to plasma proteins (99%). The average volume of distribution (Vd) is less than 0.25 l/kg, the half-life is about 0.35 hours.

Metabolism and excretion. The main route of metabolism of dexketoprofen is its conjugation with glucuronic acid, followed by excretion by the kidneys. The half-life (T1/2) of dexketoprofen is 1.65 hours. In elderly people, an extension of the half-life to 48% and a decrease in the overall clearance of the drug are observed.

Special instructions

Undesirable side effects can be minimized by using the drug in the lowest effective dose with the minimum duration of use necessary to relieve pain.

The risk of complications from the gastrointestinal tract increases in patients with a history of ulcerative lesions of the gastrointestinal tract, in elderly patients, with an increase in the dose of NSAIDs; therefore, the use of dexketoprofen in this category of patients should be started with the lowest recommended dose.

For patients in the above categories, as well as patients who require the simultaneous use of low doses of acetylsalicylic acid or other drugs that increase the risk of gastrointestinal complications, additional simultaneous use of gastroprotectors (misoprostol or proton pump blockers) is recommended.

In patients simultaneously taking antiplatelet agents or anticoagulants, glucocorticosteroids, the risk of gastrointestinal bleeding also increases.

Patients with gastrointestinal disorders or a history of gastrointestinal diseases should be under close medical supervision. If gastrointestinal bleeding or ulceration occurs, dexketoprofen therapy should be discontinued.

Dexketoprofen should be used with caution in patients with a history of gastrointestinal diseases (ulcerative colitis, Crohn’s disease), since exacerbation of these diseases is possible.

All NSAIDs can inhibit platelet aggregation and prolong bleeding time by inhibiting prostaglandin synthesis. In this regard, the use of dexketoprofen in patients simultaneously taking drugs that affect the hemostatic system, such as warfarin, coumarin derivatives and heparins, is not recommended.

Like other NSAIDs, dexketoprofen may lead to increased plasma creatinine and nitrogen concentrations. Like other prostaglandin synthesis inhibitors, dexketoprofen may have side effects on the urinary system, which can lead to the development of glomerulonephritis, interstitial nephritis, papillary necrosis, nephrotic syndrome and acute renal failure. Caution should be exercised when using the drug in patients concomitantly using diuretics and patients who may develop hypovolemia, due to the increased risk of nephrotoxicity.

As with the use of other NSAIDs, during therapy with dexketoprofen, a slight transient increase in the activity of liver enzymes may be observed. In elderly patients, monitoring of liver and kidney function is necessary. In case of a significant increase in the corresponding indicators, dexketoprofen should be discontinued.

Like other NSAIDs, dexketoprofen may mask the symptoms of infectious diseases. If signs of infection or deterioration of health are detected during dexketoprofen therapy, the patient should immediately consult a doctor.

The drug can cause fluid retention in the body, so dexketoprofen should be used with extreme caution in patients with arterial hypertension, renal and/or heart failure. If the condition worsens, use of the drug must be discontinued.

In patients with uncontrolled arterial hypertension, coronary artery disease, congestive heart failure, peripheral arterial disease and/or cerebrovascular disease, the drug should be used with caution. A similar approach is applicable to patients with risk factors for developing cardiovascular diseases (arterial hypertension, hyperlipidemia, diabetes mellitus, smoking).

Caution should be exercised when prescribing dexketoprofen to patients with a history of cardiovascular disease, especially patients with heart failure, due to the possible risk of progression.

Clinical studies and epidemiological data suggest that NSAIDs, especially in high doses and with long-term use, may lead to a small risk of acute myocardial infarction or stroke. There is insufficient data to exclude the risk of these events when using dexketoprofen.

Elderly patients are especially susceptible to adverse reactions when using NSAIDs, including the risk of life-threatening gastrointestinal bleeding and perforation, and decreased renal, liver, and cardiac function. When using dexketoprofen in this category of patients, proper clinical monitoring is necessary.

There is evidence of rare cases of skin reactions (such as exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis) with the use of NSAIDs. At the first manifestations of a skin rash, damage to the mucous membranes or other signs of an allergic reaction, you should immediately stop taking dexketoprofen and consult a doctor.

Interaction

The following interactions are common to all NSAIDs. Undesirable combinations

With other NSAIDs, including salicylates in high doses (more than 3 g per day): simultaneous use of several NSAIDs due to a synergistic effect increases the risk of gastrointestinal bleeding and ulcers.

With anticoagulants: dexketoprofen, like other NSAIDs, may enhance the effect of anticoagulants such as warfarin due to its high degree of binding to plasma proteins, inhibition of platelet aggregation and damage to the gastrointestinal mucosa. If simultaneous use is necessary, careful monitoring of the patient’s condition and regular monitoring of laboratory parameters is necessary.

With heparin: with simultaneous use, the risk of bleeding increases (due to inhibition of platelet aggregation and damaging effects on the mucous membrane of the gastrointestinal tract). If simultaneous use is necessary, careful monitoring of the patient’s condition and regular monitoring of laboratory parameters is necessary.

With glucocorticosteroids: with simultaneous use, the risk of ulcerative lesions of the gastrointestinal tract and bleeding increases.

With lithium preparations: NSAIDs increase the concentration of lithium in the blood plasma up to toxic levels, and therefore this indicator must be monitored when used simultaneously with dexketoprofen, changing the dosage, and also after discontinuation of NSAIDs.

With methotrexate in high doses (15 mg per week or more): it is possible to increase the hematological toxicity of methotrexate due to a decrease in its renal clearance when used simultaneously with NSAIDs.

With hydantoins and sulfonamides: their toxic effects may be enhanced.

Combinations requiring caution

With diuretics, angiotensin-converting enzyme (ACE) inhibitors, aminoglycoside antibiotics, angiotensin-II receptor antagonists: simultaneous use with NSAIDs is associated with the risk of developing acute renal failure in dehydrated patients (decreased glomerular filtration rate due to decreased synthesis of prostaglandins). When used concomitantly, NSAIDs may reduce the antihypertensive effect of some drugs. When using dexketoprofen and diuretics simultaneously, it is necessary to ensure that the patient has no signs of dehydration, and also monitor renal function at the beginning of simultaneous use.

With methotrexate in low doses (less than 15 mg per week): an increase in the hematological toxicity of methotrexate is possible due to a decrease in its renal clearance during NSAID therapy. Blood cell counts should be performed when coadministration is initiated. In the presence of even mild renal dysfunction, as well as in elderly people, careful medical supervision is necessary.

With pentoxifylline: there may be an increased risk of bleeding. Close clinical monitoring and regular checking of bleeding time (blood clotting time) is necessary.

With zidovudine: there is a risk of increased toxicity to red blood cells due to effects on reticulocytes, with the development of severe anemia one week after starting NSAID use. It is necessary to conduct a general blood test with a count of reticulocytes 1-2 weeks after starting NSAID therapy.

With oral hypoglycemic agents: NSAIDs may enhance the hypoglycemic effect of sulfonylureas due to their displacement from sites of binding to plasma proteins.

Combinations to consider

With beta-blockers: when used simultaneously with NSAIDs, the antihypertensive effect of beta-blockers may be reduced due to inhibition of prostaglandin synthesis.

With cyclosporine and tacrolimus: NSAIDs may increase nephrotoxicity, which is mediated by the action of renal prostaglandins. During concomitant therapy, renal function should be monitored.

With thrombolytics: increased risk of bleeding.

The risk of bleeding from the gastrointestinal tract increases when used simultaneously with serotonin reuptake inhibitors (citalopram, fluoxetine, sertraline) and anticoagulants.

With probenecid: an increase in the concentration of NSAIDs in the blood plasma is possible, which may be due to the inhibitory effect of probenecid on renal tubular secretion and/or conjugation with glucuronic acid, which requires adjustment of the NSAID dose.

With cardiac glycosides: simultaneous use with NSAIDs may lead to an increase in the concentration of cardiac glycosides in the blood plasma.

With mifepristone: due to the theoretical risk of changes in the effectiveness of mifepristone under the influence of prostaglandin synthesis inhibitors, NSAIDs should not be prescribed earlier than 8-12 days after discontinuation of mifepristone.

With quinolones: data obtained from experimental studies in animals indicate a high risk of developing seizures when NSAIDs are used concomitantly with quinolones in high doses.

If it is necessary to use dexketoprofen simultaneously with the above medications, you should consult your doctor.
