Understanding Drug Therapy: Core Pharmacologic Principles for Nursing

Course overview

Understanding the foundational principles of pharmacology is crucial for nurses and nurse practitioners responsible for administering, monitoring, and educating patients on medications. Core concepts of pharmacokinetics and pharmacodynamics - how the body affects drugs and how drugs affect the body, with an emphasis on real-world clinical applications - are explored. Drug absorption, distribution, metabolism, elimination, drug-receptor interactions, therapeutic index, and adverse drug reactions are discussed. Attention is given to pharmacologic variability across populations, polypharmacy, drug interactions, and safe medication use in special groups, such as geriatric, pediatric, and people with organ impairment. Clinical monitoring strategies, decision-making tools, and interprofessional collaboration are highlighted to help nurses optimize therapeutic outcomes and minimize risk. Practical and patient-centered, this course bridges pharmacologic science with frontline nursing practice.
