Metoprolol: Uses and Precautions

Metoprolol is a beta-blocker used to treat hypertension, angina, myocardial infarction, and other conditions. It works by blocking beta-1 receptors in the heart and blood vessels. It can be taken orally or administered intravenously. Nurses should monitor blood pressure, pulse, and side effects when administering metoprolol and educate patients about potential drug interactions and adverse reactions like fatigue, dizziness, and bronchospasm.
