What is the Importance of Pharmacokinetics and Pharmacodynamics?
Pharmacokinetics (PK) involves the study of how a drug is absorbed, distributed, metabolized, and excreted in the body. Pharmacodynamics (PD) focuses on the drug's biological effects and mechanisms of action. Together, PK and PD help in understanding the relationship between drug dosage and its therapeutic and toxic effects, aiding in optimal dosage determination.
