Pharmacological action

Pharmacotherapeutic group:

non-steroidal anti-inflammatory drug (NSAID).

ATX:

nalgesin, is a naproxen preparation, has analgesic, antipyretic and anti-inflammatory effects. The mechanism of action is associated with non-selective inhibition of the activity of cyclooxygenase 1 and 2 (COX-1, COX-2). Film-coated tablets, Nalgezin dissolve well, are rapidly absorbed from the gastrointestinal tract and provide a rapid onset of analgesic effect.

Pharmacokinetics:

Absorption from the gastrointestinal tract - fast and complete, bioavailability - 95% (food intake practically does not affect either completeness or absorption rate). The time to reach maximum concentration is 1-2 hours, the connection with plasma proteins is> 99%, the half-life is 12-15 hours. Metabolism is in the liver to dimethylnaproxen with the participation of the CYP2C9 enzyme system. Ground clearance - 0.13 ml / min / kg. It is excreted by 98% by the kidneys, 10% of them are excreted unchanged with bile - 0.5-2.5%. The equilibrium concentration is determined by taking 4-5 doses of the drug (2-3 days). With renal failure, cumulation of metabolites is possible.

Drug Interaction

When treated with anticoagulants, it should be borne in mind that

naproxen may increase bleeding time. Do not use the drug at the same time as other NSAIDs (increased risk of side effects).

Patients, concomitantly receiving hydantoins, anticoagulants, or other drugs that bind significantly to plasma proteins, should monitor for signs of potentiation or overdose of these drugs.

Nalgesin may reduce the antihypertensive action of propranolol and other beta-blockers, and may increase the risk of renal failure associated with the use of ACE inhibitors. Naproxen inhibits the natriuretic action of furosemide. Inhibition of renal clearance of lithium leads to an increase in plasma lithium concentrations. The use of probenecid increases plasma levels of naproxen.

Cyclosporine increases the risk of kidney failure.

Naproxen slows the excretion of methotrexate, phenytoin, sulfonamides, increasing the risk of their toxic action.

Magnesium and aluminum-containing antacids reduce the absorption of naproxen.

Overdose

A significant drug overdose can be characterized by drowsiness, dyspeptic disorders (heartburn, nausea and vomiting, abdominal pain), weakness, tinnitus, irritability, in severe cases - bloody vomiting, melena, impaired consciousness, convulsions and renal failure).

Patients who have received accidentally or intentionally a large amount of the drug Nalgesin should wash their stomach and undergo symptomatic therapy:

activated charcoal, antacids, H2 receptor blockers, proton pump inhibitors. Hemodialysis is ineffective.
