Abstract

A preparation method of voglibose capsules belongs to the field of pharmaceutical preparations and comprises five steps of preparation of original liquid medicine, coating drying, micronization, freeze drying and capsule filling. The voglibose capsule with high dissolution rate and good voglibose content uniformity is prepared, the dissolution rates in 5 minutes, 15 minutes and 30 minutes are respectively 53.8 to 55.9 percent, 93.6 to 96.7 percent and 99.9 to 100 percent, and the voglibose content uniformity is 0.35 to 0.43; according to the voglibose capsule preparation and the preparation method thereof, the polyvinylpyrrolidone and the superfine silica powder are added into the voglibose aqueous solution, and the rapid evaporation operation of coating drying is matched, so that the crystallization phenomenon in the voglibose precipitation process is inhibited, the voglibose in an amorphous powder state is obtained, and the final capsule preparation has excellent dissolution rate and content uniformity.

Description

technical field [0001] The invention relates to a preparation method of voglibose capsules, belonging to the field of pharmaceutical preparations. Background technique [0002] Voglibose is an α-glucosidase inhibitor, and its mechanism of action is to competitively inhibit maltase, isomaltase, glycosidase, etc. Glucose formation is reduced, thereby delaying the digestion and absorption of starch and sucrose, lowering blood sugar, and especially controlling postprandial hyperglycemia. The hypoglycemic effect of voglibose is stable and does not stimulate the secretion of insulin. There is no postprandial hyperinsulinemia, and hypoglycemia is not easy to occur. [0003] As a hypoglycemic drug, voglibose has a strict method of use and must be taken orally before meals to be effective. [0004] To control the blood sugar level after meals, to achieve this goal, voglibose must have the characteristics of rapid disintegration, high dissolution rate, and good content uniformity. ...
