It is composed of Corsartan potassium hydrochlorothiazide tablets, which is a compound antihypertensive drug, of which Corsartan potassium is an angiotensin II receptor antagonist, which can be used in clinical practice not only to lower blood pressure, but also to prevent left ventricular remodeling, reduce proteinuria, increase renal blood flow, and have certain effects on reducing uric acid. Hydrochlorothiazide tablets are diuretics, a diuretic of the thiazide class. Although its diuretic effect is not strong, it can be used in combination with coxsartan potassium to better reduce the patient’s blood pressure, which can also prevent the risk of hyperkalemia in the process of taking coxsartan potassium. The combination of these two components is generally the preferred clinical combination, and taking coxsartan potassium can also avoid the hypokalemia caused by taking hydrochlorothiazide tablets alone, so the two drugs are complementary.
