Description

technical field [0001] The invention relates to a compound preparation and an application thereof, in particular to a compound preparation containing benidipine hydrochloride and metoprolol tartrate and an application thereof, belonging to the technical field of biomedicine. Background technique [0002] Hypertension is the most prevalent disease in the world today, known as the "silent killer". Due to the development of social economy and the change of people's life style, the prevalence of hypertension in our country shows a continuous growth trend, and it has become one of the important public health problems in our country. The task of prevention and treatment of hypertension in our country is arduous. In the third national sample survey in 1991, a total of more than 900,000 people over the age of 15 were surveyed. The results showed that the crude prevalence rate of hypertension was 13.58%. During the 10 years from 1980 to 1991, the prevalence of hypertension in the Ch...
