Comparative study of mefenamic acid and dextropropoxyphene plus paracetamol in an accident and emergency department.

A randomized double-blind trial was carried out in an accident and emergency department to reassess mefenamic acid as a suitable alternative analgesic to the combination of dextropropoxyphene plus paracetamol. Analysis of data from 87 patients showed that mefenamic acid was equally effective in relieving pain and was less likely to produce adverse side-effects.
