Zatosetron (LY-277,359) is a drug which acts as an antagonist at the 5HT₃ receptor^[1] It is orally active and has a long duration of action, producing antinauseant effects but without stimulating the rate of gastrointestinal transport.^[2]^[3] It is also an effective anxiolytic in both animal studies and human trials,^[4] although with some side effects at higher doses.^[5]^[6]
