Abstract

In the realm of pharmacology, the effective use of drugs depends on two fundamental concepts: pharmacokinetics (PK) and pharmacodynamics (PD). These principles work in tandem to ensure therapeutic efficacy and safety. While pharmacokinetics focuses on the journey of a drug through the body, pharmacodynamics centres on the effects a drug expert on the body. A clear understanding of both is crucial for clinicians, researchers, and healthcare professionals aiming to optimize drug therapy.
