Which medication can be administered to relax blood vessels during coronary spasms?

Nitroglycerin is an effective medication used to relax blood vessels, particularly during episodes of coronary spasms. This type of medication works as a vasodilator, meaning it directly relaxes and widens the blood vessels, allowing for increased blood flow and reduced pressure in the cardiovascular system. By doing so, nitroglycerin helps alleviate chest pain (angina) associated with these spasms by improving oxygen delivery to the heart muscle.

In cases of coronary artery spasm, which can lead to ischemic heart pain, the rapid action of nitroglycerin can relieve symptoms quickly. This makes it particularly valuable for treating acute episodes of chest pain due to spasms or other forms of angina.

To understand the context better, other medications listed do not primarily serve this function. Aspirin is used to inhibit platelet aggregation and reduce the risk of clots. Beta-blockers manage heart rate and decrease myocardial oxygen demand but do not directly induce vasodilation. Statins are primarily aimed at lowering cholesterol levels and also do not provide immediate relief during a coronary spasm. Thus, nitroglycerin stands out as the appropriate choice for its specific ability to relax blood vessels during such events.
