§16§There is no ideal analgesic and the most potent drug is not always the best because of its side-effects. Non-opioid analgesics, including the non-steroi dal anti-inflammatory drugs and the non-narcotic analgesics, play an im portant role in the relief of a wide spectrum of painful conditions, though they vary in efficacy and safety. This book reviews the role which non-opi oid analgesics play in the relitff of pain, particularly with regard to post operative and cancer pain. Emphasis is placed on the clinical indications for the non-acidic analgesic, dipyrone, and its relative safety in comparison to other non-opioid anlgesics. Michael J.
