What is a common side effect of nitroglycerin?

• A. Increased heart rate
• B. Weight gain
• C. Stomach cramps
• D. Dehydration

Answer: (A)

Nitroglycerin is a medication commonly used in the treatment of angina pectoris and other heart-related conditions. One of the effects of nitroglycerin is to cause vasodilation, which leads to decreased cardiac workload and oxygen demand. When blood vessels dilate, it can sometimes lead to reflex tachycardia, which is an increase in heart rate. This reflexive response occurs as the body attempts to maintain adequate blood flow and blood pressure in response to the drop in systemic vascular resistance caused by vasodilation. Given this mechanism, an increased heart rate is a well recognized side effect of nitroglycerin, making it the correct answer. Other side effects of nitroglycerin may include headaches, hypotension, flushing, and dizziness, but these are not options in this question. The other choices presented—weight gain, stomach cramps, and dehydration—are not typical side effects associated with nitroglycerin and do not reflect the pharmacological effects of the drug. Understanding the physiological responses caused by nitroglycerin helps to clarify why increased heart rate is a common side effect.
