Onseron (8mg) 10 Tablets

Ondansetron 8mg Tablet primarily acts as a selective 5-HT3 receptor antagonist. This mechanism of action is crucial in preventing nausea and vomiting. By blocking these receptors, ondansetron inhibits the signals sent from the digestive system to the vomiting center in the brain. Specifically, it blocks the action of serotonin, a neurotransmitter that triggers nausea and vomiting, particularly in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This blockage suppresses the activation of 5-HT3 receptors and the subsequent emetic reflex, thereby reducing the occurrence of nausea and vomiting associated with various conditions, including chemotherapy and post-operative recovery.

Antiemetic, 5-HT3 receptor antagonist.
