There are many types of ACEI drugs, and the ones commonly used clinically include Benazepril, Perindopril, Enalapril, Fosinopril, etc. A large number of clinical studies have shown that the treatment of hypertension with Benadryl is more adequate in evidence-based medicine. At present, it is believed that Benadryl has a good inhibitory effect not only on the RAS of blood vessels, but also on the RAS of heart, brain and kidney, which is shown to inhibit the remodeling of the heart, which is good for the prevention of stroke, and is good for the reduction of urine protein and the protection of kidney. Perindopril, enalapril maleate folic acid tablets have more evidence-based medicine for stroke prevention in patients with H-type hypertension, and this group of people can choose these drugs.
