Abstract

The invention discloses an orally-taken solid medicinal composition containing trandolapril and a preparation method thereof. The orally-taken solid medicinal composition comprises the following bulk drug components in percentage by weight: 0.1-0.9 percent of trandolapril, 15-65 percent of filling agent, 10-40 percent of bonding agent, 5-40 percent of disintegrating agent and 1-8 percent of glidant. The orally-taken solid medicinal composition containing the trandolapril, which is disclosed by the invention, is suitable for treating hypertensive diseases with various degrees and is formed by processing through a scientific and reasonable production process. The orally-taken solid medicinal composition has the advantages of definite functions, controllable quality and safety in taking. The orally-taken solid medicinal composition is simple in preparation method and can be prepared by conventional equipment.

Description

technical field [0001] The invention belongs to the field of medicines, in particular to an oral solid pharmaceutical composition containing trandolapril and a preparation method thereof. Background technique [0002] 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. [0003] The blood pressure standard recommended by the World Health Organization (Who) is: the systolic blood pressure of a normal adult should be less than or equal to 140mmHg (18.6kPa), and the diastolic blood pressure should be less than or equal to 90mmHg (12kPa), that is, the systolic...
