Summary

The efficacy of ranitidine in the treatment of NSAID-related dyspeptic symptoms with and without peptic ulcer disease (PUD) was investigated in 124 patients with rheumatoid arthritis (RA) and osteoarthritis (OA). The patients, who continued the use of NSAIDs were investigated by gastroduodenoscopy. Patients with PUD received open label ranitidine 150 mg b.i.d. and the patients without PUD were randomly allocated to receive ranitidine 150 mg b.i.d. or placebo for 4 weeks. PUD was found in 36 (26%) consecutive patients who presented with dyspeptic symptoms. Of these patients dyspeptic symptoms had disappeared in 8 (26%) of 31 evaluable patients and PUD was healed in 18 (56%) patients after 4 weeks of treatment. After 8 weeks of treatment PUD was healed in 27 (87%) patients. Of the remaining patients without PUD dyspeptic symptoms had disappeared in 24 (26%) of the ranitidine-treated patients which was significantly better (p<0.02) than the 5 (6%) placebo-treated patients. The minor mucosal lesions found in this patient group improved to a similar extent in the ranitidine and placebo-treated patients although 1 placebo-treated patient deteriorated and 2 placebo-treated patients developed PUD during the 4 weeks of study. The results of this study show that oral ranitidine 150 mg b.i.d. is effective in the treatment of both dyspeptic symptoms and mucosal lesions in RA and OA patient who continue the use of NSAIDs.
