Receptor Site Pharmacology

Meaning

Receptor Site Pharmacology is the specialized field of pharmacology that focuses on the precise mechanisms of drug and hormone action at the cellular receptor level, including binding affinity, dynamic receptor density, and the subsequent downstream signal transduction pathways. This discipline is fundamentally concerned with optimizing the critical interaction between a therapeutic agent and its target receptor to maximize efficacy and simultaneously minimize off-target or adverse effects. It represents the molecular foundation of targeted endocrine and neurochemical therapy.
