Description
Tropisetron

Tropisetron is a highly potent and selective competitive antagonist of the 5-HT3 receptor. Tropisetron selectively blocks the excitation of the presynaptic 5-HT3 receptors of the peripheral neurons in this reflex, and may exert additional direct actions within the CNS on 5-HT3 receptors mediating the actions of vagal input to the area postrema.
