ICD-10 Specific code M11: Other crystal arthropathies

Acemetacin is a glycolic acid ester of indomethacin and the pharmacological activity resulting from acemetacin administration in man is derived from the presence of both acemetacin and indomethacin. The precise pharmacological mode of action of acemetacin is not known. However, unlike other NSAIDs, acemetacin is only a relatively weak inhibitor of prostaglandin synthetase.

Acetylsalicylic acid combines significant advantages such as strong anti-pyretic, analgesic and anti-inflammatory action, that is the measure of comparison with all the newer NSAIDs.

Etofenamate is a flufenamic acid derivative, which is readily transported through the skin and concentrated in inflamed tissue, where it exerts anti-inflammatory and analgesic effects by inhibiting the release of histamine, lysosomal enzymes and prostaglandin.

Flurbiprofen is a propionic acid derivative NSAID which acts through inhibition of prostaglandin synthesis. In humans flurbiprofen has potent analgesic, antipyretic and anti-inflammatory properties.

Meloxicam is a non-steroidal anti-inflammatory drug (NSAID) of the oxicam family, with anti-inflammatory, analgesic and antipyretic properties. The anti-inflammatory activity of meloxicam has been proven in classical models of inflammation. As with other NSAID, its precise mechanism of action remains unknown. However, there is at least one common mode of action shared by all NSAID (including meloxicam): inhibition of the biosynthesis of prostaglandins, known inflammation mediators.

Nimesulide is a non-steroidal anti-inflammatory drug with analgesic and antipyretic properties which acts as an inhibitor of prostaglandin synthesis enzyme cyclo-oxygenase. Cyclo-oxygenase produces prostaglandins, some of them being implicated in the development and maintenance of inflammation.

Triamcinolone acetonide is a more potent derivative of triamcinolone and is approximately 8 times more potent than prednisone. Although the precise mechanism of corticosteroid anti-allergic action is unknown, corticosteroids are very effective in the treatment of allergic diseases in man. Also, local injections are thought to have an anti-inflammatory effect.
