title: A controlled comparison of dipyrone and paracetamol in post-episiotomy pain.
abstract: A double-blind, placebo-controlled trial was carried out in 299 patients suffering from post-episiotomy pain to compare the analgesic effectiveness and tolerance of single doses of 500 mg dipyrone and 500 mg paracetamol. Assessments of pain relief over a 6-hour period showed that dipyrone produced significantly better results than placebo within half an hour of intake and maintained this superiority throughout the 6 hours. It also afforded consistently better pain relief than paracetamol and was significantly more effective at the 6-hour assessment. Side-effects were few and mild.
