As the therapeutic agent, nitric acid and nitrite compounds, calcium antagonists, β-blockers and the like have been used, but their effects are still insufficient for the treatment of angina and the prevention of myocardial infarction. More recently, due to changes in lifestyles and increased stress associated with social complications, the age of angina patients has declined and the pathophysiology has become complicated.

報告されており、臨床上問題となっている。Of the above-listed agents currently in use, one is the most frequently used, and the oldest is the nitric acid and nitrite compounds,
It is considered that cyclic GMP (hereinafter abbreviated as cGMP) among cyclic nucleotides known as intracellular second messenger is involved in this action. For cGMP, the relaxing action of vascular smooth muscle and bronchial smooth muscle is well known. Although the mechanism of action of these drugs is not always clear, this cGM
The activity of P activates guanylate cyclase, resulting in cGM
It is generally believed to be due to promoting P synthesis. However, these agents have low bioavailability and relatively short duration of action. Further, it has been reported to cause resistance, which is a clinical problem.
