Abstract

The invention discloses a medicinal composition for treating hypertension, and belongs to the field of medicaments. The antihypertensive medicinal composition comprises a pharmaceutically effective dose of levoamlodipine or a pharmaceutically acceptable salt thereof and losartanpotassium, wherein the levoamlodipine is weighed in free alkali; the losartan is weighed in free acid; and the weight ratio of the levoamlodipine to the losartan is 1 to 11-19. The medicinal composition does not damage the target organ while reducing the blood pressure so as to enhance the therapeutic effect and reducethe risk for therapy of a patient.

Description

technical field [0001] The invention belongs to the field of medicine and relates to a pharmaceutical composition for treating hypertension. Background technique [0002] Hypertension is the most common cardiovascular disease and has become a major public health problem worldwide. According to statistics from the national health department, by the end of 2006, the number of hypertensive patients in my country had reached 160 million, and more than 3 million new patients were added every year.
