Ondansetron, ampoules 2mg/ml, 2ml, 5pcs

Composition

1 ampoule contains:

Active ingredient:

 ondansetron (in the form of dihydrate hydrochloride) 2 mg

Pharmacological action

Ondansetron is an antiemetic.

Ondansetron effectively prevents and eliminates nausea and vomiting that occur during antitumor chemotherapy or radiation therapy, as well as in the postoperative period. The mechanism of action is due to the ability of ondansetron to selectively block serotonin 5-HT3 receptors.

It is believed that the stimulation of afferent fibers of the vagus nerve with serotonin released from enterochromaffin cells of the gastrointestinal mucosa plays an important role in the occurrence of nausea and vomiting during antitumor therapy. By blocking 5-HT3 receptors, ondansetron prevents the occurrence of a gag reflex.

In addition, ondansetron inhibits the central links of the gag reflex, blocking the 5-HT3 receptors of the bottom of the IV ventricle (area postrema).

Indications

Prevention of nausea and vomiting during antitumor chemotherapy or radiation therapy; prevention and treatment of nausea and vomiting in the postoperative period.
