Abstract

The invention relates to a trandolapril-containing pharmaceutical composition. The composition is prepared from, by weight, 1-2 parts of trandolapril, 10-60 parts of a filling agent, 5-45 parts of adhesives, 4-36 parts of a disintegrating agent, 2-10 parts of a flow aid and 4-6 parts of a lubricating agent, wherein the lubricating agent is a mixture of cinnamyl magnesium sulfate and magnesium stearate in a weight ratio of 1:1.7-2.1. The trandolapril-containing pharmaceutical composition has advantages that by synergistic effects and strict control of ratios of components, efficacies of the pharmaceutical composition is greatly improved; in addition, stability and controllability in quality and safety and effectiveness in clinical application are realized, and the pharmaceutical composition can be completely disintegrated in water within 2min and is convenient to store, transport and carry.

Description

technical field [0001] The invention belongs to the field of medicines, in particular to a pharmaceutical composition containing trandolapril [0002] and its preparation method. Background technique [0003] Hypertension is defined as elevated arterial systolic and / or diastolic blood pressure at rest. Hypertension is a systemic disease characterized by elevated arterial pressure, which may be accompanied by functional or organic changes in the heart, blood vessels, brain, kidneys and other organs. It has primary hypertension and secondary hypertension points. There are many reasons for the onset of hypertension, which can be divided into two aspects: genetic and environmental. [0004] In addition, elevated blood pressure is also the fuse of many diseases, which will increase the risk of coronary heart disease, heart failure and kidney diseases. Since some hypertensive patients have no obvious clinical symptoms, hypertension is also known as the "invisible killer" of hu...
