Basic Pharmacology Understanding Drug Actions and Reactions

WebbAfter studying quantitative aspects of drug action, Clark (1937) propounded a theory of drug action based on occupation of receptors by specific drugs and that the pace of a cellular function can be altered by interaction of these receptors with drugs which, in fact, are small molecular ligands. WebbThe receptor occupation theory of drug action equates drug effect to receptor occupancy. The intensity of drug effect is proportional to the number of receptors that are occupied by drug and the maximum effect occurs when all receptors are occupied by drug.
