Biological Activity for Ondansetron hydrochloride

Ondansetron hydrochloride is a selective 5-HT₃ receptor antagonist (K_i= 6.16 nM). Also an inhibitor of human multidrug and toxin extrusion (MATE) transporter 1 (IC₅₀ = <10-160 nM). Ondansetron blocks 5-HT-evoked transient inward currents (IC₅₀= 0.1 nM) in human recombinant h5-HT_3A receptors. In an animal model of Parkinson's disease, Ondansetron reduces both the severity of dyskinesia and psychosis-like behaviors. Antiemetic; prevents emesis induced by cytotoxic drugs and radiation.
