Synthetic substances with morphine-like effect: clinical experience; potency, side-effects, addiction liability

Bull World Health Organ. 1957;17(4-5):569-863.


A review of effects in man of morphine-like drugs which have been brought under international narcotics control is presented in the form of individual monographs. These are based on controlled observations with quantitative data and significant reports of results obtained in medical practice. In a summarizing section, the drugs are compared with respect to effectiveness, side-effects and addiction liability. Morphine-like drugs of natural and synthetic origin now cover a wide range of potency (analgesic, antitussive), not necessarily paralleled by incidence of side-effects or addiction liability.
