PY - 2022 T2 - Pharmacology in Rehabilitation, 5e AB - A receptor is a component on or within a cell that a substance can bind to.1 Most drugs exert their effect by binding to and activating one of these receptors.1 The receptors can be any cellular macromolecule, but many receptors have been identified as proteins or protein complexes that are located on or within the cell.1,2 When a drug binds to a receptor, it initiates a chain of biochemical events that brings about some change in the physiological function of the cell.
