Tablets comprising olmesartan medoxomil and method for preparing same

Abstract

The invention discloses tablets comprising olmesartan medoxomil and a method for preparing the tablets. The tablets are prepared from olmesartan medoxomil micro pills, a disintegrating agent, a filler and a lubricating agent, wherein the olmesartan medoxomil micro pills are prepared by dispersing the olmesartan medoxomil on the surfaces of ball-shaped lactose pill cores and wrapping by isolating coating. The olmesartan medoxomil is made into medicine-carrying micro pills, then the olmesartan medoxomil micro pills are wrapped by the isolating coating, and the olmesartan medoxomil micro pills are mixed with other medicinal accessories and directly pressed into the tablets, therefore, the purpose of covering the bad smell of the olmesartan medoxomil is achieved, and the stability and the dissolution rate of the medicine are improved.

Description

technical field

[0001] The invention belongs to the technical field of western medicine preparations, in particular to a tablet containing olmesartan medoxomil and a preparation method thereof. Background technique

[0002] Olmesartan medoxomil (olmesartan medoxomi l) is an angiotensin Ⅱ (Ag Ⅱ) antagonist antihypertensive drug newly developed by Japan's Sankyo (Sankyo), and it has been listed for the first time in the United States. Olmesartan medoxomil is a substituted imidazole drug, which is significantly superior to other similar products such as losartan, valsartan, and irbesartan in terms of overall efficacy in reducing diastolic blood pressure. It has good drug tolerance and no cough side effects compared with ACE inhibitors, and is an oral safe and effective high-efficiency antihypertensive drug that is easily accepted by patients.

[0003] The chemical name of olmesartan medoxomil is 2,3-dihydroxy-2-butenyl-4-(1-hydroxy-1-methylethyl)-2-butyl-1-[4-(2-1H -tetrazoli...
