Indication: Clinically applicable to the prevention and treatment of angina pectoris caused by coronary heart disease, especially variant angina pectoris and angina pectoris caused by coronary artery spasm. Applicable to various types of hypertension, and also has good efficacy on refractory and severe hypertension. Raynaud's syndrome. Because it can reduce afterload, it also has good efficacy on refractory congestive heart failure and is suitable for long-term use. In addition, it is also suitable for patients with angina pectoris suffering from obstructive respiratory diseases, and its efficacy is better than beta-receptor blockers.
