Pharmacodynamics

Topic: Pharmacology

What a drug does to the body: how it produces its effects, mostly by binding to receptors, enzymes or ion channels. An agonist activates a receptor, an antagonist blocks it, and a partial agonist produces a weaker effect. Potency, efficacy and the dose-response relationship describe how much drug is needed and how large an effect it can produce; tolerance is a smaller response with repeated use. Together with pharmacokinetics, it explains why the same drug affects people differently. Assess the expected therapeutic effect and the adverse effects of every drug you give.
