Abstract

The invention relates to a pharmaceutical composition containing valsartan and amlodipine besylate and a preparation method. The composition takes valsartan and amlodipine besylate as raw materials, and comprises pharmaceutically acceptable excipients of microcrystalline cellulose, crosslinked sodium carboxymethyl cellulose, silica and sodium stearyl fumarate. The preparation method comprises following steps: carrying out dry granulation on the raw materials and part of the excipients firstly, and adding the sodium stearyl fumarate to carry out tabletting and coating to be produced into film-coated tablets. The preparation method is characterized in that the dry granulation is adopted to avoid the influence of moisture on main ingredients during wet granulation, and the sodium stearyl fumarate serves as a lubricant instead of commonly used magnesium stearate to prevent the influence of the magnesium stearate on the main ingredients, therefore on the premise of disintegrating and dissolving the product better, the product quality is further stabilized and the drug safety is enhanced.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a pharmaceutical composition containing valsartan amlodipine besylate and a preparation method thereof. Background technique [0002] With the improvement of human living standards, hypertension has become the most common cardiovascular disease. According to WHO forecast, non-communicable diseases will account for 79% of the causes of death in my country by 2020, among which cardiovascular diseases will rank first. Statistics show that there are more than 130 million hypertensive patients in my country, but the control of blood pressure is not ideal, and patients often fail to reach the target recommended by the guidelines. Therefore, it is imperative to vigorously carry out the prevention and active treatment of hypertension. [0003] Long-term poorly controlled hypertension can seriously damage target organs such as the heart, brain, and kidneys. Active treatment can reduce car...
