Although morphine is the mainstay of pharmacological therapy in cancer pain, it remains feared and suboptimally used. Different formulations and the advent of 'new' opioids facilitate the attainment of pain control. ⋯ The optimal application of opioids is governed by their clinical pharmacology and hindered by unfounded fears and misunderstanding. Different formulations within different types of opioids augment a favourable balance in the pain relief versus adverse effects equation and used within a four point approach, should serve to deliver optimal pain control.
