Used primarily in the treatment of angina pectoris, especially chronic stable angina. It acts as a vasodilator by releasing nitric oxide, which relaxes blood vessels and improves blood flow to the heart. This reduces the workload on the heart and decreases myocardial oxygen demand. Unlike some other anti-anginal drugs, molsidomine does not cause significant reflex tachycardia, making it suitable for long-term management. It is also investigated for potential benefits in patients with endothelial dysfunction due to its nitric oxide-donating properties.
