Abstract

A pharmaceutical composition for treating hypertension and a preparation method of the pharmaceutical composition are disclosed. The invention provides compound reserpine tablets, which comprise reserpine, hydrochlorothiazide, vitamin B6, vitamin B1, calcium pantothenate, magnesium trisilicate, potassium chloride, dihydralazine sulfate, promethazine hydrochloride and a pharmaceutically-acceptable carrier, wherein vitamin B1 is available in the form of coated granules.

Description

technical field [0001] The invention relates to a pharmaceutical composition containing reserpine for treating hypertension and a preparation method thereof, belonging to the technical field of medicines. Background technique [0002] Reserpine is an adrenergic nerve inhibitory drug, which can prevent the storage of mediators in adrenergic nerve endings and deplete the mediators in the vesicles that have a pressor effect. Because of its mild but long-lasting antihypertensive effect, it is generally used in combination with vasodilators and diuretics. Dihydralazine sulfate is a vasodilator that relaxes arteriolar smooth muscle and reduces peripheral resistance. Hydrochlorothiazide and other diuretic antihypertensive drugs. The combined use of reserpine, vasodilators and diuretics has a significant synergistic effect, which promotes the decline of blood pressure, improves the curative effect, and reduces the dose and adverse reactions of each drug; in addition, hydrochloroth...
