1․3 Key Concepts in Pharmacology
Key pharmacology concepts include pharmacokinetics, pharmacodynamics, and drug-receptor interactions․ These principles explain how drugs are absorbed, distributed, metabolized, and excreted, and how they interact with biological systems to produce therapeutic effects, forming the foundation for understanding drug mechanisms and applications․
Pharmacokinetics and Pharmacodynamics
Pharmacokinetics examines drug absorption, distribution, metabolism, and excretion, while pharmacodynamics studies drug effects and receptor interactions․ Together, they explain how drugs work in the body․
2․1 Absorption, Distribution, Metabolism, and Excretion (ADME)
ADME processes determine drug concentration and effectiveness․ Absorption involves drug uptake into the bloodstream, while distribution carries drugs to target tissues․ Metabolism breaks drugs down, often in the liver, and excretion eliminates them via kidneys or bile․ These processes influence drug efficacy, toxicity, and duration of action․
2․2 Drug-Receptor Interactions
Drug-receptor interactions involve drugs binding to specific cellular receptors, triggering biological responses․ Ligands, such as drugs, bind to receptors with varying affinity, influencing efficacy․ Agonists activate receptors, while antagonists block them․ These interactions determine therapeutic effects, side effects, and drug specificity, forming the basis of pharmacotherapy and drug development strategies․
2․3 Dose-Response Relationships
Dose-response relationships describe how drug effects vary with dosage․ Graded responses occur in individuals, while quantal responses measure population effects․ The therapeutic index compares effective and toxic doses, guiding safe prescribing․ Understanding these relationships optimizes treatment efficacy and minimizes adverse effects, crucial for clinical practice and drug development․
