Sulphasalazine, sulphapyridine or 5-aminosalicylic acid--which is the active moiety in rheumatoid arthritis? 1995

Sulphasalazine is cleaved into 5-aminosalicylic acid and sulphapyridine by colonic bacteria. The bulk of evidence favours sulphapyridine rather than 5-aminosalicylic acid as the active moiety (as well as the main producer of side-effects) though a therapeutic action from the 30% of sulphasalazine that is absorbed unaltered also cannot be excluded.

D000894	Anti-Inflammatory Agents, Non-Steroidal	Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
