What does the term 'pharmacodynamics' refer to?

Pharmacodynamics specifically refers to the study of the effects of drugs on the body, encompassing how drugs exert their effects at various biological targets. This includes understanding drug action mechanisms, the relationship between drug concentration and effect, and the pharmacological response an individual experiences as a result of medication administration. This field examines factors such as drug efficacy, potency, and the therapeutic and toxic effects associated with drug use. By focusing on these aspects, pharmacodynamics provides essential insights into how medications can be used effectively and safely in treating medical conditions.
