The use of intramuscular meptazinol in the relief of post-operative pain after abdominal hysterectomy--a review.

In previously published studies of post-abdominal hysterectomy pain control reviewed here, meptazinol in doses of 50, 75 and 100 mg intramuscularly (i.m.) caused significant dose-related pain relief. Meptazinol 100 mg i.m. was equipotent as an analgesic when compared with either Omnopon 20 mg i.m., pentazocine 60 mg i.m. or pethidine 100 mg i.m. Meptazinol in doses of 60, 75 and 100 mg i.m. was not significantly different from pethidine 100 mg in relieving pain when assessed by the pain relief score.
