<p>Celecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor, non-steroidal anti-inflammatory drug (NSAID). It exhibits anti-inflammatory, analgesic and antipyretic properties. The mechanism of action of Celecoxib is believed to be due to the inhibition of prostaglandin synthesis, via the inhibition of cyclooxygenase-2 (COX-2) enzyme. At therapeutic concentration, Celecoxib does not inhibit cyclooxygenase-1 (COX-1) isoenzyme.</p>
