Tương tác
Increased INR with anticoagulants (e.g. warfarin). May diminish the therapeutic effect of diuretics and antihypertensive agents. May increase the risk of gastrointestinal ulceration with aspirin (even at low doses). Increased plasma concentrations of ethinylestradiol, lithium, methotrexate, and other drugs metabolised by human sulfotransferases (e.g. oral salbutamol, minoxidil). Decreased plasma concentrations with rifampicin.
Tác dụng
Description: Etoricoxib, an NSAID, is an orally active, highly selective cyclo-oxygenase-2 (COX-2) inhibitor. Its anti-inflammatory and analgesic action is exhibited by inhibition of prostaglandin synthesis via inhibition of COX-2.
Pharmacokinetics:
Absorption: Well absorbed from the gastrointestinal tract. Absolute bioavailability: Approx 100%. Time to peak plasma concentrations: Approx 1 hour (without food).
Distribution: Plasma protein binding: Approx 92%.
Metabolism: Extensively metabolised by the CYP3A4 isoenzyme to form the 6'-hydroxymethyl derivative of etoricoxib, which undergoes further oxidation to form the major metabolite 6'-carboxylic acid derivative.
Excretion: Mainly via urine (70% as metabolites; <2% as unchanged drug); faeces (20% as metabolites; <62% as unchanged drug). Elimination half-life: Approx 22 hours.
