Used primarily in the treatment of chronic stable angina pectoris, this compound acts as a long-acting vasodilator. It helps improve blood flow to the heart by relaxing coronary arteries, thereby reducing the frequency and severity of angina attacks. Unlike nitrates, it does not cause tolerance with prolonged use, making it a suitable alternative for patients who cannot tolerate nitrate-based medications. It is also investigated for its potential benefits in patients with endothelial dysfunction due to its ability to release nitric oxide, a key molecule in vascular regulation.
