Mechanism of action

Palonosetron is a selective serotonin 5-HT3 receptor antagonist that has a longer half-life compared to other 5-HT3 antagonists, allowing for once-daily dosing. This mechanism of action helps to prevent the activation of the 5-HT3 receptors in the central nervous system, which are responsible for nausea and vomiting.
