Pharmacotherapy for cancer pain: an anaesthesiologist's viewpoint

Cancer pain is prevalent and undertreated despite the availability of therapeutic options that, taken together are highly effective, economical and safe. Improved understanding of the pharmacology of chronically-administered opioids has resulted in reduced concerns about addiction and an increased emphasis on their use. The anaesthetist may play a pivotal role in cancer pain management by the provision of nerve blocks and other interventions, but, to be a truly effective consultant, must also be expert in all aspects of pharmacotherapy. A rationale for the development of pharmacologic expertise together with a review of assessment and pharmacologic management of cancer pain are provided.
