Danetro (4mg/5ml) 50ml Syrup

Ondansetron 4mg syrup/suspension acts as a highly selective 5-HT3 receptor antagonist. Its primary mechanism of action is to block serotonin (5-HT3) receptors in the chemoreceptor trigger zone and the gastrointestinal tract. By inhibiting these receptors, ondansetron prevents the activation of the vomiting center in the brain and reduces nausea and vomiting. This drug effectively competes with serotonin for binding to these receptors, thereby suppressing serotonin-mediated neuronal signals that trigger the vomiting reflex. Ondansetron's selectivity for 5-HT3 receptors contributes to its antiemetic properties without significantly affecting other neurotransmitter systems.

Ondansetron is a 5-HT3 receptor antagonist.
