Non-Nitrate Coronary Vasodilators

"Non-nitrate coronary vasodilators" is a descriptive, heterogeneous pharmacological category rather than a single standardized regulatory drug class These agents promote coronary artery dilation and enhance myocardial perfusion through mechanisms independent of nitric oxide donation, primarily including calcium channel blockers like diltiazem and verapamil, adenosine receptor agonists such as dipyridamole, and direct arteriolar relaxants

These agents promote coronary artery dilation and enhance myocardial perfusion through mechanisms independent of nitric oxide donation, primarily including calcium channel blockers like diltiazem and verapamil, adenosine receptor agonists such as dipyridamole, and direct arteriolar relaxants By reducing coronary vascular resistance and lowering myocardial wall tension or oxygen demand, they counteract ischemia and suppress vascular spasm

Clinically, medications in this grouping are predominantly utilized in the prevention and management of chronic stable angina, vasospastic (Prinzmetal) angina, and as pharmacological stress agents during myocardial perfusion imaging
