Abstract

The present invention utilizes ultramicropulverization and dripping pill preparation production process to make domperiodine dripping pills, and can attain the goal of raising disintegration and dissolution speed, quickly obtaining therapeutic effect, raising stability of medicine, reducing dose of auxiliary material, reducing production cost and convenient administration. Said pill not only can be sucked, but also can be swallowed, and its compliance property is good.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method thereof, in particular to domperidone dripping pills and a preparation method thereof. Background technique [0002] Domperidone is a peripheral dopamine receptor blocker, acting directly on the gastrointestinal wall, increasing the tension of the lower esophageal sphincter, preventing gastroesophageal reflux, enhancing gastric motility, promoting gastric emptying, coordinating gastric and duodenal motility, inhibiting Nausea, vomiting, and can effectively prevent bile reflux without affecting gastric secretion. Domperidone does not easily pass through the blood-cerebrospinal fluid barrier and has no inhibitory effect on dopamine receptors in the brain. Therefore, it has no extrapyramidal and other neurological and mental adverse reactions. [0003] Domperidone is rapidly absorbed after oral administration, and the peak plasma concentration can be reached within 15 to 30 mi...
