Abstract

The invention provides a candesartan/hydrochlorothiazide capsule and a preparation method thereof. The invention has the obvious advantages as follows: on the one hand, the invention can obviously reduce the blood pressure of a hypertensive patient, effectively protect the heart, the brain and the kidney organ and reduce the incidence of complications and has safety, effectiveness, high tolerance,and the like; on the other hand, the invention also has the advantages of less tablet process link, short production period, less quality control points of production process, and the like besides keeping the advantages of accurate dosage, convenient application, stable quality, convenience for carrying, transport and storage, high degree of production mechanization and automatization, large yield, and the like of the prior tablet/dispersible tablet and can simplify the industrial production, thereby being beneficial to the reduction of drug production and management costs and the selection of doctors and patients for cheap and good drugs.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a candesartan / hydrochlorothiazide capsule and a preparation method thereof. Background technique [0002] Since the treatment of hypertensive diseases is long-term, it is advisable to choose drugs with mild effects and fewer adverse reactions. At present, it is believed that the purpose of hypertension treatment is to prevent and reduce the damage of target organs and prolong life, so it is required to lower blood pressure to a certain low level and maintain this level. In order to meet this requirement, a single antihypertensive drug cannot meet the clinical treatment requirements, so two or more drugs need to be used in combination. The most commonly used clinical treatment of hypertension is the combination of diuretics and beta-receptor blockers, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, etc. [0003] Candesartan cilexetil / hydrochlorothiazide c...
