Problems solved by technology

However, the preparation of such capsules requires special equipment, and is limited by the size of the capsule shell, so it is generally only suitable for low-dose main drugs
When a large dose is required, the capsule shell becomes larger accordingly. For a large capsule shell, its dissolution behavior will not only affect the dissolution of the main drug, but also affect the compliance of the patient. It is considered that the large capsule shell is not safe

Abstract

This invention is a multilayer tablet contains calcium channel acceptor retarder and ACE inhibitor. Its feature is that it contains calcium channel acceptor retarder pleated sheet and ACE inhibitor pleated sheet. The calcium channel acceptor retarder pleated sheet contains levamlodipine or amoldipine or salt that can be accepted on pharmacy of them. The ACE inhibitor pleated sheet contains methylphenidate or its pharmacy accepted salt. They can be produced by normal medicine equipment, and preparation is easy, the multilayer tablet made can be quickly disintegrated, main medicine component can be quickly stripped, and its quality stability is good.

Description

technical field [0001] The present invention relates to a multi-layer tablet, which contains the calcium channel receptor blocker amlodipine or levoamlodipine sheet and the ACE inhibitor benazepril sheet, and the invention also provides the preparation of the multi-layer tablet Methods. Background technique [0002] Amlodipine (Amlodipine) is the third generation of dihydropyridine calcium antagonists, which began to be used clinically in the 1990s. In addition to its good antihypertensive effect, it also has a unique anti-atherosclerotic effect. After binding to the receptor, the dissociation speed is slow, the effect appears later and lasts longer, and the selectivity to blood vessels is higher than that of nifedipine. Unlike other calcium channel receptor blockers, amlodipine has no effect on myocardial conduction and contractility, so reflex tachycardia does not occur, and is suitable for the treatment of various types of hypertension and stabl...
