Osetron® 8 mg / 4 mL injection contains ondansetron hydrochloride. Doctors use this medicine to prevent and control nausea and vomiting.
Many medical treatments can cause nausea. For example, chemotherapy, radiotherapy, and surgery often trigger vomiting. However, medicines like Osetron® injection help control these symptoms. Therefore, patients feel more comfortable during treatment.
Ondansetron blocks the effect of serotonin, a chemical that triggers vomiting. As a result, the brain receives fewer signals that cause nausea. Consequently, the patient experiences less vomiting.

Doctors give this medicine directly into a vein (IV) or into a muscle (IM). Because of this, the medicine works quickly. Therefore, hospitals often use it during medical procedures.
Ondansetron belongs to a group of medicines called 5-HT3 receptor antagonists.
Serotonin can activate the vomiting center in the brain. However, ondansetron blocks these serotonin receptors. Therefore, the vomiting reflex becomes weaker.
In addition, this medicine works both in the brain and digestive system. As a result, it controls nausea from several causes.
Doctors widely use ondansetron because it works quickly. Moreover, most patients tolerate it well.
