Ondansetron-Altfarm, rectal 16 g mg 2 pcs

Ondansetron is a selective 5HTH3 (serotonin) receptor antagonist.

The drugs for cytostatic chemotherapy and radiotherapy can cause increased levels of serotonin, which by activation of vagal afferent fibers containing 5-HT3 receptors, causes the gag reflex.

Ondansetron inhibits the onset of the gag reflex by blockade of 5-NT3 receptors at the neuronal level of both the central and peripheral nervous system.

Apparently this mechanism of action is the basis for the prevention and treatment of postoperative and cytostatic chemo- and radiotherapy-induced vomiting and nausea.

Indications

Prevention of nausea and vomiting during antitumor chemotherapy or radiation therapy;

prevention and treatment of nausea and vomiting in the postoperative period.

Pharmacological effect

Ondansetron is a selective 5HT3 (serotonin) receptor antagonist.

Cytostatic chemotherapy drugs and radiotherapy can cause an increase in serotonin levels, which, by activating vagal afferent fibers containing 5-HT3 receptors, causes the gag reflex.

Ondansetron inhibits the appearance of the gag reflex by blocking 5-HT3 receptors at the level of neurons in both the central and peripheral nervous systems.

Apparently, this mechanism of action is the basis for the prevention and treatment of postoperative vomiting and nausea caused by cytostatic chemotherapy and radiotherapy.
