Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
A double-blind comparison of nefopam and placebo in post-operative pain.
Nefopam (90 mg), an analgesic, was compared with placebo in a double-blind trial in patients who had undergone total abdominal hysterectomy operations. Analgesic activity was assessed by patients rating their pain before and 1 hour after administration of each treatment, by sequential analysis of patient and observer preference for treatment, and by calculation of the time interval between doses of the two treatments. Nefopam was found by observer preference to be significantly better than placebo in relieving post-operative pain. In patients with severe initial pain, the time between doses after nefopam was significantly longer than after placebo.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of nefopam and pethidine in postoperative pain.
A double-blind, between-patient, two-dose comparison was comparison was performed with pethidine and nefopam in 100 subjects, the majority of whom were recovering from upper abdominal surgery. Either 15 or 30 mg of nefopam or 50 or 100 mg of pethidine were given by i.m. injection in a random order. All assessments were made by the same observer on the first day after operation, at least 4 h after the previous analgesic injection. ⋯ Pethidine 100 mg provided significantly better pain relief than nefopam 30 mg, the latter being not more effective than nefopam 15 mg apart from the duration of analgesia which was longer. The incidence of nausea and vomiting was similar after both drugs. Sweating and tachycardia were observed more frequently after nefopam, whereas sedative side-effects were more common after pethidine.
