5 DRUG DESCRIPTION: Celecoxib is chemically designated as 4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl] benzene sulfonamide and is a diaryl-substituted pyrazole. It has the following chemical structure: MECHANISM OF ACTION:  Celecoxib is a highly selective COX-2inhibitor, about 10 – 20 times more selective for COX -2 than for COX-1.  COX-2 selective inhibitors, were developed in an attempt to inhibit prostacyclin synthesis.  It is done by COX-2 ISO enzyme Induced at sites of inflammation without affecting the action of the constitutively active “house keeping” COX-1 ISO enzyme found in the GI tract, kidneys, and platelets.  COX-2 inhibitors have analgesic, anti-pyretic, and anti-inflammatory effects similar to those of non-selective NSAID s.
