Clinical Trials

A clinical trial sponsored by Beijing Chao Yang Hospital evaluates the therapeutic efficacy and safety of Tropisetron for preventing postoperative cognitive dysfunction and postoperative delirium. Designed as a late-stage Phase IV, randomized, double-blind, placebo-controlled study, its current recruitment status is documented as unknown. Overall, this research reflects interest in utilizing Tropisetron to attenuate perioperative neurocognitive impairments following surgical procedures.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Tropisetron functions as a 5-HT3 receptor antagonist with an IC50 of 70.1 nM and acts as an α7-nicotinic acetylcholine receptor agonist, thereby inhibiting serotonin-mediated ion channel gating while enhancing cholinergic signaling pathways. This dual action modulates central neurotransmitter release and suppresses neuroinflammatory cascades, providing a rational mechanistic basis for mitigating postoperative cognitive dysfunction and postoperative delirium.
