preparation example Construction

[0075] In some embodiments, the preparation method of the sitagliptin coated pellets specifically includes the following steps:

[0076] a. The sitagliptin and the filler are pulverized and sieved separately, mixed evenly and then mixed with the binder, and the sitagliptin-containing pellet core is prepared by the extrusion spheronization method.

[0077] B, the Surelease aqueous dispersion is mixed with water to prepare the Surelease aqueous dispersion coating solution;

[0078] c, get the ball core containing sitagliptin and place it in the fluidized bed, and coat the ball core containing sitagliptin with Surelease aqueous dispersion coating solution;

[0079] Wherein, step a and step b are in no particular order.

[0080] Wherein, in some preferred embodiments, in the preparation method of the sitagliptin-coated pellets, the sieving in step a is 100-mesh sieve.

[0081] In some preferred embodiments, in the preparation method of the sitagliptin coated pellets, the specifi...

Abstract

The invention belongs to the field of medicine preparation science, and particularly relates to a sustained-release composition of sitagliptin and simvastatin, a preparation method of the sustained-release composition, and a sustained-release preparation of sitagliptin and simvastatin. The sustained-release composition of the sitagliptin and the simvastatin disclosed by the invention is composed of a sitagliptin coated pellet and a simvastatin sustained-release pellet at the mass ratio of (10:1) to (1:1). The sustained-release composition of the sitagliptin and the simvastatin is simple in prescription and process; the sitagliptin and the simvastatin can be slowly released within 24 hours; the sitagliptin and the simvastatin always work together, so that the plasma drug concentration can be well stabilized; the peak valley phenomenon of the plasma drug concentration is avoided; the toxic and side effects on a human body caused by the medicine are reduced; the bioavailability of the medicine is improved; the medication frequency is reduced; and the compliance of a patient is improved. The preparation method of the sustained-release composition of the sitagliptin and the simvastatin disclosed by the invention is simple to operate, and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a sitagliptin-simvastatin sustained-release composition, a preparation method and a sitagliptin-simvastatin sustained-release preparation. Background technique [0002] Sitagliptin is a triazolylpiperazine compound with a β-amino acid structure, and its chemical name is (2R)-4-oxo-4-[3-(trifluoromethyl)5,6-dihydro- [1,2,4]triazolo[4,3-α]pyrazin-7(8H)-yl)-1-(2,4,5-trifluorophenyl)butan-2-amine. Sitagliptin is a dipeptidyl peptidase (DPP-4) inhibitor, which exerts its active effect by slowing down the inactivation of incretin hormone in patients with type II diabetes, and its specific structural formula is as follows: [0003] [0004] Simvastatin, the chemical name is 2,2-dimethylbutanoic acid-, 1,2,3,7,8,8a-hexahydro-3,7-dimethyl-8-[2-(tetrahydro- 4-Hydroxy-6-oxo-2H-2-pyranyl)-ethyl]-1-naphthyl ester. Simvastatin is a prodrug, and after administration,...
