Mexidon Uses, Dosage, Side Effects, Food Interaction and all others data.

Mexidon is a nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, anti-pyretic, and analgesic properties. It inhibits prostaglandin synthetase/cyclooxygenase, which limits prostaglandin production. Its cyclooxygenase inhibiting potency is intermediate, but is relatively selective for the cyclo-oxygenase-2 (COX-2) thus the potential for gastric injury and intolerance is less. It is also a free radical scavenger, and helps protect against the tissue damage that occurs during inflammation.

Food, gender and advanced age have negligible effects on nimesulide pharmacokinetics.

Additive hepatotoxic effects with known hepatotoxins: anti-convulsants (e.g. valproic acid), anti-fungals (e.g. ketoconazole), anti-tuberculous drugs (e.g. isoniazid), tacrine, pemoline, amiodarone, methotrexate, methyldopa, amoxicillin/clavulanic acid. May decrease the oral bioavailability of furosemide and the natriuretic and diuretic response to furosemide. Increased risks of GI and hepatic adverse effects with other NSAIDs, including aspirin. May increase anti-coagulant effect of warfarin. Potentiates the action of phenytoin. May be displaced from binding sites with fenofibrate, salicylic acid, and tolbutamide. Interactions between NSAIDs and lithium, probenecid and ciclosporin, have been documented.
