Mosapride Citrate

Synonyms: Mosapride citrate, 112885-42-4, 4-Amino-5-chloro-2-ethoxy-N-[[4-[(4-fluorophenyl)methyl]morpholin-2-yl]methyl]benzamide citrate, Gasmotin

Mosapride citrate is a prokinetic agent that selectively stimulates 5-HT4 receptors in the gastrointestinal tract. Its benzamide core, substituted with a 4-fluorobenzyl morpholine moiety, gives the molecule high affinity for serotonin receptor subtypes while avoiding significant interaction with dopamine D2 receptors. This selectivity underpins its clinical use for dyspepsia and gastroesophageal reflux, where it accelerates gastric emptying without the extrapyramidal side effects associated with older prokinetics.

The compound is synthesized through a multi-step route starting from 4-amino-5-chloro-2-ethoxybenzoic acid. The citrate salt form enhances aqueous solubility and stability, making it suitable for oral solid dosage forms. It is supplied as a fine crystalline powder with consistent particle size distribution, ideal for direct compression or wet granulation.

In pharmaceutical development, mosapride citrate serves as a reference standard and active ingredient for immediate-release tablets and suspensions. Its well-characterized pharmacokinetic profile—rapid absorption, extensive first-pass metabolism via CYP3A4—makes it a preferred model compound for studying prokinetic mechanisms and formulation strategies.

Chemical Structure & Properties

Mosapride citrate is a citrate salt of a benzamide derivative. The molecule features a 4-fluorobenzyl group attached to a morpholine ring, which is linked via a methylene bridge to the benzamide core. This structure confers lipophilicity and receptor selectivity. The citrate counterion improves crystallinity and dissolution rate. The compound is stable under normal storage conditions, with a melting point range of 148–152°C (decomposition).

Mechanism of Action

• 5-HT4 receptor agonism: Enhances acetylcholine release in the enteric nervous system, promoting peristalsis and gastric emptying.
• Selectivity: Minimal affinity for 5-HT3, dopamine D2, and adrenergic receptors, reducing off-target effects.
• Accelerated gastric emptying: Improves antral motility and coordination, beneficial in functional dyspepsia.
• No QT prolongation: Unlike some prokinetics, mosapride citrate has not shown significant cardiac conduction delays in clinical studies.
