1. Why Pharmacology Matters in Nursing
Pharmacology is the study of drugs, their actions on the body, and how the body responds to them. For
nurses, understanding pharmacology is critical because:
1. Patient Safety: Medication errors are among the most common causes of adverse events in
healthcare. Knowing drug mechanisms, dosages, and side effects prevents harm.
2. Clinical Decision-Making: Nurses must anticipate patient responses, recognize adverse effects,
and implement interventions quickly.
3. Exam Success: NCLEX, HESI, and other exams heavily focus on medication knowledge and
safe dosage calculations.
Example: A nurse administering digoxin without understanding its narrow therapeutic range may miss
early signs of toxicity (nausea, bradycardia, visual disturbances). Awareness prevents serious
complications.
Clinical Tip: Always ask, ―What is the purpose of this drug? What am I monitoring? What is the
patient’s response?‖
2. Key Principles of Pharmacology
2.1. Pharmacokinetics – What the Body Does to the Drug
Pharmacokinetics involves absorption, distribution, metabolism, and excretion (ADME):
1. Absorption: How the drug enters the bloodstream.
o Oral drugs: Absorbed via GI tract → liver (first-pass effect) → systemic circulation.
o IV drugs: 100% bioavailability; fastest onset.
2. Distribution: How the drug spreads through body tissues.
o Highly protein-bound drugs (e.g., warfarin) compete for binding sites; low albumin
increases free drug.
3. Metabolism: Chemical modification of drugs, mostly in the liver.
o Drugs may be activated or inactivated; liver disease affects metabolism.
4. Excretion: Removal of drugs, mainly via kidneys.
o Renal impairment requires dosage adjustment.

Clinical Tip: Monitor kidney and liver function before giving medications with narrow therapeutic
ranges.
2.2. Pharmacodynamics – What the Drug Does to the Body
Pharmacodynamics refers to the mechanism of action, therapeutic effects, and side effects of a drug:
