Morphine can adversely affect which medications given for ACS pts?

• A. Oral antiplatelet medications
• B. Intravenous beta-blockers
• C. Nitroglycerin tablets
• D. Heparin

Answer: (A)

Morphine can slow stomach emptying and gut motility, which delays the absorption and onset of effect of drugs taken by mouth. In ACS care, rapid antiplatelet action is crucial, and oral antiplatelet agents (like clopidogrel) rely on timely GI absorption to inhibit platelets quickly. By delaying this absorption, morphine can blunt or delay the early antiplatelet effect, making it the most likely to be adversely affected. Intravenous beta-blockers, nitroglycerin tablets (often used sublingually or IV), and heparin do not depend on slow GI absorption in the same way, so they’re not impacted by morphine in the same manner.
