Abstract

The invention discloses a slow release capsule of trimebutine or the salt thereof and a preparation method thereof. The slow release capsule of trimebutine or the salt thereof is prepared by adding the accessories of filler, adhesive and slow release materials and the like into the trimebutine, wherein, the trimebutine can be replaced by the maleate thereof or other medicinal salts. The slow release capsule of trimebutine or the salt thereof can be obtained through the following preparation processes: a pill core is first prepared by adopting microcrystalline cellulose or starch and the like through centrifugation, spray cementing, powder supply, polishing and other processes and coated with a medicated layer to prepare a medicated pill core, which is then coated with a slow release film to make a trimebutine slow release mini-pill, finally the slow release capsule of trimebutine or the salt thereof is obtained after filling the mini-pill in a capsule. Compared with the common preparation, the slow release capsule can continue with drug delivery for up to 12 hours, and has comparably stable blood concentration and long time to peak. And the preparation method of the capsule is characterized by good repeatability and easy operation and the like.

Description

field of invention [0001] The invention relates to a preparation of trimebutine or a salt thereof and a preparation method thereof, in particular to a trimebutine or a salt thereof sustained-release capsule and a preparation method thereof. technical background [0002] Trimebutine, commonly used its maleate, (English name: trimebutine maleate, abbreviation: TMB), structural formula is as follows: [0003] [0004] It is a gastrointestinal rhythm agent different from cholinergic drugs and anti-dopamine drugs. It is mainly used clinically to treat gastrointestinal symptoms (abdominal distension, abdominal pain, nausea, belching) and irritable bowel syndrome caused by chronic gastritis. disease. [0005] The relevant characteristics of trimebutine are as follows: [0006] 1. Unlike cholinergic drugs and anti-dopamine drugs, which are gastrointestinal motility regulators, trimebutine can promote and inhibit bidirectional regulation of gastrointestinal motility due to diffe...
