Early forms of the receptor theory of pharmacology stated that a drug's effect is directly proportional to the number of receptors that are occupied. Furthermore, a drug effect ceases as a drug-receptor complex dissociates. Ariëns & Stephenson introduced the terms "affinity" & "efficacy" to describe the action of ligands bound to receptors. Webb2 feb. 2009 · Nevertheless, receptor theory undoubtedly provided the foundation on which the study of receptor function at the biochemical and molecular level was based, so its importance in the early stages cannot be doubted.
