The composition and form of issue
Ondansetron solution for in/in and/m introduction:
1 ampoule contains ondansetron (in the form of hydrochloride dihydrate) 2, 4 and 8 mg, 10 pieces in pack.
Pharmacological action
Antiemetic. Ondansetron effectively prevents and eliminates nausea and vomiting, occurring on the background of anticancer chemotherapy or radiation therapy, as well as in the postoperative period. The mechanism of action is due to the ability of ondansetron selectively block serotonin 5-HT3-receptors. I believe that in the occurrence of nausea and vomiting in anticancer therapy important role played by the stimulation of afferent fibers of the vagus nerve by serotonin released from enterochromaffin cells of gastrointestinal mucosa. Blocking 5-HT3 receptors, ondansetron prevents gag reflex. In addition, ondansetron oppresses the Central links of the gag reflex by blocking 5-HT3 receptors bottom of the IV ventricle (area postrema).
