Abstract

1 Mixed agonist-antagonist analgesics have analgesic action but also possess a range of side-effects. 2 Narcotic antagonists do not reverse the non-specific effects of opiates. 3 Under certain circumstances the effects of agonists and mixed agonist-antagonists can be additive. 4 Chronic dosage of mixed agonist-antagonists leads to a lower level of dependence than that observed with the standard narcotics. 5 Mixed agonist-antagonists may not antagonize the respiratory effects of narcotics and may result in potentiation of such depression.
