Ondansetron may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of ondansetron. The investigators therefore will perform the present study to measure the effect of ondansestron on the blood coagulation pathway according to the drug concentration level using a thromboelastography test.
