Indoprofen--a new non-opioid analgesic. A comparison with pethidine.

Indoprofen (400 mg), a non-opioid, non-steroidal anti-inflammatory drug, was compared on a random, double-blind basis with pethidine (1,5 mg/kg) after elective caesarean section (40 patients) and after orthopaedic surgery (40 patients). The drugs were given intravenously during anaesthesia and provided adequate analgesia for a period of up to 2 hours postoperatively. No significant differences between the two drugs were noted in terms of efficacy and side-effects.
