Pharmacology
Odatron 2 mg/ml is a selective 5-HT3 receptor antagonist.
However, cytotoxic chemotherapy appears to be associated with release of serotonin from the enterochromaffin cells of the small intestine.
Serotonin receptors of the 5-HT3 type are present both peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone of the area postrema.
It is not certain whether Odatron 2 mg/ml's antiemetic action is mediated centrally, peripherally, or in both sites.
