We performed a 12-month, double-blind, randomised, placebo-controlled study to determine the long term effect of misoprostol (600-800 micrograms/d) in the prevention of gastric ulcers and gastroduodenal erosions in 83 arthritis patients on chronic NSAID therapy. Patients underwent endoscopy at 0, 3, 6 and 12 months. At the initial endoscopy, 12 patients had an ulcer (11 gastric), which was healed prior to randomization. Seventy eligible patients reached the 3 month endoscopy. Four (12.5%) of the 32 patients given misoprostol developed a gastric ulcer compared with 11 (28.9%) of the 38 on placebo (p < 0.05, life-table analysis). Six of the 11 patients with an initial gastric ulcer developed a further gastric ulcer, compared to 9 of 58 patients without an initial ulcer (p < 0.05). We conclude that misoprostol decreases the cumulative development of NSAID-induced gastric ulcers. Patients with a previous NSAID-ulcer have a higher risk of further ulceration.

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.
