Gyógyszerélettannal, also known as pharmacodynamics, is the study of how drugs interact with the body to produce their effects. It explores the biochemical and physiological changes that occur in response to a drug, as well as the mechanisms by which these changes are brought about. This field investigates both the intended therapeutic effects and the potential adverse or side effects of medications.

Key aspects of pharmacodynamics include understanding drug targets, such as receptors, enzymes, or ion channels, and how drugs bind to these targets to initiate a response. It also examines the relationship between drug concentration at the site of action and the magnitude of the observed effect, often described by dose-response curves. Factors influencing a drug's pharmacodynamic profile include the drug's chemical structure, its affinity for the target, and the physiological state of the individual.

Pharmacodynamics is crucial for determining appropriate drug dosages, predicting therapeutic outcomes, and understanding why different individuals may respond to the same medication in varying ways. It forms a fundamental pillar of pharmacology, alongside pharmacokinetics, which describes how the body handles a drug (absorption, distribution, metabolism, and excretion). Together, these disciplines inform drug development, clinical practice, and the safe and effective use of medicines.
