Etorcoxib is a selective inhibitor of COX-2. The COX-1 isoenzyme is constitutely expressed in most tissues and is
particularly invloved prostaglandin snthesis in the kidneys, platelets and gastric mucosa, products of of COX-1
appear cytoprotective and inhibition of this isoform has been associated with antiplatelet activity and gastrointestinal
toxicity. On the other hand the inhibition of of COX-2y etoricoxib is responsible for its analgesic and anti-inflammatory
and its low incidence of adverse effects.
Etoricoxib is rapidly absorbed with a mean bioavailability of approximately 100%. Food does not significantly affect
absorption. Etoricoxib undergoes extensive metabolism by the hepatic cytochrome enzymes, mostly by the
CYP 450 3A4
It has an elimnation half-life of aproximately 22 hours and a plasma clearance of 3 litres/hour. Most of the drug is
eliminated by the kidneys and a part is eliminated through the faeces.
Interaction with Food:
Food does not significantly affect absorption.
Pregnancy and lactation:
Preganancy and lactation- caution to be excercised
