Abstract

The invention discloses a pediatric domperidone suspension and a preparation method thereof. The suspension comprises domperidone, an antibacterial agent, a corrective, a suspending agent, a masking agent and a diluent, wherein the suspending agent and the masking agent both are montmorillonite, the average particle size of the montmorillonite is 8 to 27 [mu]m, and the dosage of the montmorillonite is 0.22% to 4.34% (w / w) of the total amount of the formula. According to the invention, the suspension is prepared by processes of preparing the domperidone with montmorillonite hydrogels, hydrogel microparticles with a rapid diffusion controlled drug release mechanism, a drug-containing suspension and the like, so that the problems of low drug dissolution rate, bitterness and the like are successfully solved to greatly improve the medication compliance and provide a good effect for functional dyspepsia of children.

Description

technical field [0001] The invention relates to a drug for gastrointestinal motility, in particular to a children's domperidone suspension and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Domperidone, the first peripheral dopamine receptor blocker, increases lower esophageal sphincter pressure and improves gastric emptying by increasing gastric emptying and promoting antrum-duodenal coordination. Upper gastrointestinal motility plays a key role in the pathogenesis of functional epigastric discomfort. [0003] Anorexia caused by insufficient gastric motility in children, also known as functional dyspepsia in children, refers to the long-term loss of appetite or lack of appetite in children due to lack of gastric motility. Anorexia affects children's growth and development, nutritional status, and intellectual development. Long-term anorexia can lead to malnutrition anemia, rickets, low immunity, and repeated respi...
