Comparative assessment of fenoprofen and paracetamol given in combination for pain after surgery

In a double-blind study of patients suffering from pain after surgery, fenoprofen 200 mg and paracetamol 500 mg was compared with each drug given separately and with a placebo. There was a significant difference between the combination and the placebo, whereas, separately, the drugs were only marginally better than the placebo in relieving pain. There was a significant linear trend indicating a better clinical result as the number of active components in the regimen was increased.
