Pharmacodynamics

Pharmacodynamics is the branch of pharmacology that studies how drugs affect the body. It explores the relationship between drug concentration and the resulting effects on biological systems. Essentially, it looks at what a drug does after it enters the body, including its mechanism of action, therapeutic effects, and potential side effects. Understanding pharmacodynamics helps in determining the right dosage and ensuring that medications are both effective and safe for patients. This knowledge is crucial in developing new drugs and optimizing existing treatments in medicine.
