Abstract

The invention provides a compound preparation of valsartan amlodipine tablet (I) and a preparation method thereof. The compound preparation comprises a tablet, a film coating layer, the tablet comprises main drug and auxiliary materials, the main drug comprises valsartan, benzenesulfonic acid amlodipine, the auxiliary material comprises filler, a disintegrating agent, a lubricant, and glidant, the tablet comprises the valsartan, benzenesulfonic acid amlodipine, the filler, the disintegrating agent, the lubricant and the glidant, and the tablet is obtained by being coated with the film coating layer. According to the method, the defect of unsafety of medicine use caused by increase of relevant material due to wet granulation is overcome, and manufacture cost can be lowered and labor intensity can be relieved due to the dry granulation technology.
