Pharmacodynamics studies the effects of a drug on biological systems, and pharmacokinetics studies the effects of biological systems on a drug. Pharmacodynamics :    W hich refers to the molecular, biochemical, and physiological effects of drugs, including drug mechanism of action .   Pharmacodynamics refers to the relationship between drug concentration at the site of action and the resulting effect, including the time course and intensity of thera- peutic and adverse effects. The effect of a drug present at the site of action is determined by that drug's binding with a receptor.
