OBJECTIVE: Methotrexate (MTX) is an increasingly popular anti-rheumatic drug with its usefulness limited by toxicity, most commonly gastrointestinal (GI). The aim of the study was to study the effectiveness of the 5-HT3 receptor antagonist granisetron (GR) in the therapy of MTX-induced nausea. METHODS: A single-blind 8 week pilot study with random allocation to either GR 1 mg or prochlorperazine (Stemetil; PCh) 10 mg was undertaken in 13 patients who were taking or had taken MTX for either rheumatoid arthritis (10) or psoriatic arthritis (3). RESULTS: One in six patients treated with PCh completed the 8 week study compared to 7/7 treated with GR. After switching of symptomatic patients, 11 completed the study on GR and median improvement was by two grades (P < 0.001) with a significantly better visual analogue scale score for patient satisfaction compared to PCh. CONCLUSION: Treatment with GR may be useful in establishing and maintaining some patients on MTX where GI toxicity would have precluded such therapy.
