WebbThe receptor theory is as important and basic to pharmacology as the atomic theory is to physical sciences. The drug-receptor interaction implies a mutual molding of drug and receptor like a lock and its matching key. The drug receptor interaction is usually reversible; it obeys the law of mass action and usually involves ionic bonds, hydrogen ... WebbSpringer

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. Webb1 apr. 2004 · Pharmacological receptor theory is discussed with special reference to advances made during the past 25 years. Thus, the operational model has supplanted analysis of drug–receptor interaction in functional systems whereas the extended ternary complex model is used routinely to simulate quantitatively G-protein-coupled receptor …
