🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a partial agonist at the serotonin 5-HT4 receptors located in the gastrointestinal tract. By binding to these receptors, it stimulates the release of acetylcholine and other neurotransmitters from enteric neurons, which enhances peristalsis and accelerates gastrointestinal transit. Additionally, it reduces visceral hypersensitivity, which contributes to its analgesic effect on abdominal pain.
