Therapeutic Efficacy of Ramosetron for Treatment of Established PONV After Laparoscopic Surgery

Ondansetron also has been reported as effective prophylactic and therapeutic 5-HT3 receptor antagonist for the treatment of PONV. Ramosetron has been shown to have a very strong effect for preventing PONV in previous meta-analyses, but in recent report, its clinical significance may be questioned to request for additional study.

Ramosetron is a newly developed selective 5-HT3 (5 hydroxytryptamine 3) receptor antagonist with longer duration of action up to 48hours and higher receptor affinity, than its previously developed congeners, including ondansetron.
