🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with distinct mechanisms. Ondansetron selectively blocks 5-HT3 receptors in the gastrointestinal tract and the central nervous system, preventing serotonin from triggering the vomiting reflex. Ranitidine competitively blocks histamine H2 receptors on gastric parietal cells, reducing both basal and stimulated gastric acid secretion. Together, they address nausea and vomiting while reducing stomach acid, which can help alleviate associated discomfort.
