Abstract

The invention discloses a microporous membrane-coated controlled-release trelagliptin succinate pellet and a preparation method thereof. The microporous membrane-coated controlled-release trelagliptin succinate pellet sequentially comprises a drug-containing pellet core and a controlled-release coating layer from inside to outside, wherein the drug-containing pellet core is prepared from a primary material and an auxiliary material at the ratio of (5%-20%):(80%-95%). According to the microporous membrane-coated controlled-release trelagliptin succinate pellet, a bitter taste can be coated, the effective ingredients can be dissolved out, constant long-acting plasma concentration is ensured, and the defect that a drug is discharged along with excrement before not completely released is avoided.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations for animals, more specifically, to a microporous membrane controlled-release coated diacerein pellet and a preparation method thereof. Background technique [0002] 1. Pharmacological and clinical effects [0003] Diacerelate is the primary inhibitor of IL-1 in osteoarthritis. It has been confirmed by cell experiments and animal experiments that the pharmacological effects of this product mainly include (1) this product can induce cartilage production, has analgesic, anti-inflammatory and antipyretic effects; (2) does not inhibit the synthesis of prostaglandins; (3) has the effect on bone Arthritis has the effect of delaying the progression of the disease. Pharmacokinetic studies have shown that in animals and humans, orally administered diacerein undergoes deacetylation into the active metabolite rhein before entering the systemic circulation. The peak time of a single oral administr...
