Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a pharmaceutical composition containing valsartan and amlodipine besylate and a preparation method thereof. Background technique [0002] Hypertension has become a major public health problem worldwide. Nearly 1 billion people worldwide suffer from hypertension, and it is estimated that the number will reach 1.5 billion in 2025. The countries with the highest incidence of hypertension in the world are about 40% in African Americans, about 38% in England, Sweden and Italy, about 45% in Spain, and about 55% in Germany. At present, the incidence of hypertension in China has exceeded 25%, and this rising trend is still continuing. Statistics show that the treatment rate of hypertension in my country is 17.4% in urban areas and 5.4% in rural areas; the control rate after treatment is only 2.9%. Therefore, statistics show that the prevalence of hypertension in m...
