Abstract

The invention relates to an itopride hydrochloride controlled-release tablet combination. The technical scheme includes that an itopride hydrochloride controlled-release tablet comprises a tablet core and a coating layer; the itopride hydrochloride controlled-release tablet is characterized in that the tablet core contains itopride hydrochloride, polyethylene glycol 1000, lactose, mannitol, aerosil and povidone K30, and the coating layer contains ethyl cellulose and hydroxypropyl methyl cellulose. By the technical scheme, the problem that release rate of single-chamber itopride controlled-release tablets can reach about 70% only is solved, and a pharmaceutical which is safe, effective and high in utilization rate is provided for clinical medication.

Description

technical field [0001] The invention relates to an itopride hydrochloride controlled-release tablet composition. Background technique [0002] Itopride hydrochloride increases the release of acetylcholine through the antagonism of dopamine D2 receptors, and at the same time inhibits the decomposition of released acetylcholine through the inhibition of acetylcholinease, thereby enhancing the motility of the stomach and duodenum. This product has a good gastric motility effect and is suitable for various symptoms caused by functional dyspepsia. It can enhance the contractility of the stomach and duodenum, accelerate gastric emptying, and have the effect of inhibiting vomiting. [0003] The commercially available itopride preparation is a regular-release dosage form, 50 mg per tablet, 1 tablet each time, 3 times a day for patients. No controlled-release itopride tablets are marketed. [0004] Ordinary itopride tablets are taken 3 times a day, and the blood drug concentration ...
