<p>Sulindac is a non-steroidal antirheumatic agent possessing anti-inflammatory, analgesic and anti-pyretic properties. Prostaglandin synthetase inhibition is probably the basis of the mechanism of action of non-steroidal anti-inflammatory agents. Following absorption, Sulindac undergoes two major transformations. It is oxidised to the sulphone and then reversibly reduced to the sulphide. The sulphide metabolite is the biologically active form which is an inhibitor of prostaglandin synthesis.</p>
