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.

The ligand binds to the receptor, which triggers a signaling cascade inside the cell. The signaling cascade causes the ion channel to open, allowing cations to flow down their concentration gradient and into the cell, resulting in a depolarization. channel 9 player

"Webb29 jan. 2010 · Although receptors remained somewhat enigmatic hypothetical entities until quite recently, they provided a basis for the theoretical analysis of the quantitative actions of drugs, both in eliciting a response (agonists) and in antagonizing it (antagonists). Several such theories to account for the actions of drugs have been proposed. " - Receptor theory
