Nitroglycerin is commonly used as a vasodilator to relieve chest pain associated with angina and other cardiac conditions. One of the well-known side effects of nitroglycerin is hypotension, which refers to a drop in blood pressure. When nitroglycerin is administered, it relaxes the smooth muscles in blood vessels, resulting in vasodilation. This process increases the capacity of the blood vessels and can lead to a decreased preload (the amount of blood returning to the heart). As a result, there is often a reduction in systemic vascular resistance, which can contribute to a drop in blood pressure. Patients taking nitroglycerin may experience symptoms of hypotension such as dizziness, lightheadedness, or even fainting, especially when changing positions quickly. Other options, while pertinent to cardiovascular considerations, do not align with the typical, common side effects seen with nitroglycerin administration. Increased heart rate often occurs as a compensatory mechanism in response to hypotension, but it is not a direct effect of nitroglycerin. Severe arrhythmias are not a recognized common side effect linked specifically to nitroglycerin use, and dehydration is not associated with nitroglycerin’s action. Therefore, hypotension
