Biological Activity

Description Mosapride is a gastroprokinetic agent that acts as a selective 5HT4 agonist.
5HT4 [1]
In vitro

Mosapride facilitates acetylcholine release from the enteric cholinergic neurons. It does not block K+ channels or D2 dopaminergic receptors[2]. Mosapride is a selective 5-HT4 receptor agonist with no affinity for 5-HT1, 5-HT2, adrenalineα1, adrenalineα2 or dopamine D2 receptors[3].

In vivo Mosapride augmented lower gastrointestinal motility in animal models and in patients with lower gastrointestinal disorders. It enhanced defecation responses in animal models. In human, after oral administration of single doses of mosapride 5-40 mg, peak mosapride concentrations (Cmax) were reached after about 1 hour. Both the Cmax and area under the concentration-time curve from time zero to infinity (AUC∞) increased in a dose-proportional manner. There were no significant differences in the pharmacokinetic profiles of mosapride administered as single or multiple doses. Mosapride is excreted in the urine and faeces. It is primarily metabolized in the liver by cytochrome P450 3A4 to the active metabolite, a des-4-fluorobenzyl compound[3].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
