PHARMACOLOGICAL AND CLINICAL IMPORTANCE OF NARCOTIC-ANTAGONISTS AND MIXED ANTAGONISTS - USE IN CARDIOLOGY

1 The treatment of pain of cardiac origin requires a knowledge of the haemodynamic action of the analgesic agents used. 2 The haemodynamic effects of morphine, diamorphine, pavaveretum, pethidine and pentazocine are reviewed. 3 Clinical experience with the new antagonist analgesic buprenorphine is reported. 4 These studies indicate that buprenorphine may be the agent of choice for the relief of severe pain in patients with unstable circulation. 1979 The British Pharmacological Society
