Nitroglycerin is the drug identified as a vasodilator, and it works by relaxing the smooth muscles within the blood vessels. This relaxation leads to dilation, which helps to decrease blood pressure and reduce the workload on the heart. It is commonly used in the treatment of conditions such as angina, heart failure, and hypertensive emergencies, where the goal is to improve blood flow and oxygen delivery to the heart muscle while easing the strain on it.

In clinical situations, the effects of vasodilation can lead to improvements in symptoms for patients experiencing chest pain or those with cardiac issues, making nitroglycerin a critical medication in emergency and advanced care settings. The other options do not possess vasodilatory effects; they serve different therapeutic purposes, making nitroglycerin specifically suited for the indicated role.
