Which medication is used for rapid relief during angina pectoris?

• A. Morphine sulfate or fentanyl
• B. Baby aspirin
• C. Sublingual nitroglycerin
• D. All of the above

Answer: (C)

Rapid relief of angina comes from a fast-acting vasodilator that quickly lowers the heart’s oxygen demand. Sublingual nitroglycerin fits this need because it is absorbed quickly through the under-tongue mucosa, bypassing the liver, so its onset is within minutes. It primarily dilates veins at usual anti-anginal doses, which lowers preload and reduces myocardial workload, easing chest pain quickly. While morphine or fentanyl can help with pain and anxiety, and aspirin has a preventative antiplatelet effect, neither provides the same immediate relief for an acute angina episode as nitroglycerin. For best effect, use one dose first, reassess after a few minutes, and repeat if needed and allowed by the patient’s blood pressure and medical conditions.
