What are the Key Components of Pharmacokinetics and Pharmacodynamics?
Pharmacokinetics involves four main processes: 1. Absorption: How the drug enters the bloodstream. 2. Distribution: How the drug is dispersed throughout the body. 3. Metabolism: How the drug is broken down, often in the liver. 4. Excretion: How the drug is eliminated, typically via kidneys or bile.
Pharmacodynamics focuses on: - Mechanism of action: How the drug produces its therapeutic effect. - Receptor binding: Interaction of the drug with cellular receptors. - Therapeutic window: The range of drug concentration that yields efficacy without toxicity.
