Abstract
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...
