Peripheral vasodilator APIs are a class of compounds that dilate peripheral blood vessels and are mainly used clinically to treat hypertension, myocardial infarction, hypertensive heart disease, acute left heart failure, and pulmonary edema after open heart surgery, as well as acute, chronic cardiac insufficiency. Commonly used peripheral vasodilator APIs include vascular smooth muscle relaxant APIs, such as hydralazine, sodium nitroprusside, and nitrates, as well as alpha-adrenoceptor blockers, calcium antagonists, and angiotensin-converting enzyme inhibitors.
