Captopril is an angiotensin-converting enzyme inhibitor, which can be taken for a long time and is a good drug in clinical practice. Generally speaking, for patients with hypertension with proteinuria, or hypertension with diabetes, the effect of taking the drug is relatively better, which can help reduce proteinuria, and also prevent the occurrence and development of heart failure and myocardial ischemia. Captopril is a short-acting antihypertensive drug, so it is not used very much in the clinic at present.
