Problems solved by technology

[0005] Elderly people generally have poor swallowing ability and clinical compliance is not very good
In addition, trimebutine maleate has a persistent unbearable astringent taste
The current oral trimebutine maleate conventional tablet produces a strong numb taste and bitter taste when the medicine contacts with the tongue, making it impossible for people to continue taking it. Therefore, it is necessary to prepare a trimebutine maleate The preparation can not only overcome the numbness and bitterness produced by the medicine when taken orally, but also overcome the poor swallowing ability of the elderly

Abstract

The invention relates to a Trimebutine Maleate suspension, which comprises 7 to 25 percent of Trimebutine Maleate particles, 1.5 to 7.5 percent of coating material, 60 to 85 percent of flavoring agent and 3 to 7 percent of suspending aid, wherein the Trimebutine Maleate particles are Trimebutine Maleate crystal particles or medicine particles containing Trimebutine Maleate. The Trimebutine Maleate suspension provided by the invention can effectively hide the unpleasant odor of a Trimebutine Maleate raw material and improve the obedience in patients; and the preparation is highly soluble, can be taken conveniently and helps to solve the difficult swallowing problem of old patients.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to pharmaceutical preparations for treating gastrointestinal diseases, in particular to trimebutine maleate dry suspension and a preparation method thereof. Background technique [0002] Trimebutine maleate was first listed in Japan in the mid-1970s. It is used as a gastrointestinal motility regulator to treat gastrointestinal disorders, such as irritable bowel syndrome, gastrointestinal dysfunction caused by chronic gastritis, and surgery. It has been used for nearly 40 years in foreign countries and nearly 10 years in China for post-gastrointestinal disorders. Pharmacological studies have shown that trimebutine maleate regulates gastrointestinal motility and lower esophageal sphincter pressure by acting on peripheral opioid receptors, gastrointestinal smooth muscle and affecting the release of gastrointestinal peptides, and induces propulsion in the digestive system. Ex...
