preparation example Construction

[0204] During the preparation of the coated tablet (A), it is preferable to form an inactive intermediate layer between the inner core and the outer layer to avoid direct contact between the inner core and the outer layer. The intermediate layer contains, for example, the above-mentioned coating base and coating additives. The intermediate layer preferably comprises an aqueous film coating base (preferably hydroxypropylmethylcellulose) and an opacifier and / or colorant (preferably talc).

[0205] In the above-mentioned coated tablet (A), the outer layer is formed at a ratio of preferably 0.1-100 parts by weight, more preferably 1-50 parts by weight, still more preferably 3-30 parts by weight, relative to 100 parts by weight of the inner core.

[0206] Moreover, in the above-mentioned coated tablet (A), the intermediate layer is formed at a ratio of preferably 0.1-30 parts by weight, more preferably 0.5-20 parts by weight, still more preferably 1-5 parts by weight, relative to 1...

Abstract

The present invention provides a solid preparation containing compound (I) [compound (I) is as defined in the specification] or a salt thereof, and metformin hydrochloride, which is useful as a therapeutic drug for diabetes and the like, and superior in the preservation stability. A solid preparation having a first part and a second part:a first part: a part containing compound (I) or a salt thereof and substantially free of metformin hydrochloride a second part: a part containing metformin hydrochloride and substantially free of compound (I) and a salt thereof.

Description

technical field [0001] The present invention relates to a solid preparation excellent in storage stability, a method for producing the same, and a method for stabilizing compound (I). The solid preparation contains 2-[[6-[(3R)-3-amino-1-piperidinyl]-3,4-dihydro-3-methyl-2,4- Dioxo-1(2H)-pyrimidinyl]methyl]benzonitrile (common name: alogliptin; hereinafter sometimes referred to as compound (I)) or a salt thereof and metformin hydrochloride. Background technique [0002] Compound (I) or a salt thereof used in the present invention has been reported as an inhibitor of dipeptidyl peptidase (DPP-IV), which degrades glucagon-like peptide-1 ( GLP-1), a hormone that enhances insulin secretion (WO2005 / 095381). [0003] There has been a report on the combined administration of compound (I) or a salt thereof used in the present invention and metformin hydrochloride (WO2007 / 033266). [0004] However, a preparation comprising compound (I) or a salt thereof and metformin hydrochloride ...
