Y1 - 2015 N1 - T2 - Goodman & Gilman's: The Pharmacological Basis of Therapeutics, 12e AB - Pain is a component of virtually all clinical pathologies, and management of pain is a primary clinical imperative. Opioids are a mainstay of pain treatment, but rational therapy may involve, depending upon the pain state, one or more drug classes, such as NSAIDs, anticonvulsants, and antidepressants. The properties of these non-opioid agents are presented in Chapters 34, 21, 15. This chapter focuses first on the biochemical, pharmacological, and functional nature of the opioid system that defines the effects of opioids on pain processing, gastrointestinal-endocrine-autonomic functions, and reward-addiction circuits. Subsequently, the chapter presents principles that guide the use of opioid and non-opioid agents in the management of clinical pain states.
