NCT03017222

Brief Summary

Patients who had at least two risk factors of PONV (Postoperative nausea and vomiting) and underwent laparoscopic surgeries under general anesthesia were assessed for eligibility. Patients who developed PONV within the first 2 hours after anesthesia received intravenously, in a randomized double-blind manner, ondansetron 4 mg or ramosetron 0.3 mg. Patients were then observed for 24 hours after drug administration. The incidence of nausea and vomiting, severity of nausea, requirements for rescue antiemetic and adverse effects at 0-2 and 2-24 hours after drug administration were evaluated. The primary endpoint was the rate of patients exhibiting complete response, defined as no emesis and no further rescue antiemetic medication for 24 hours after drug administration.

Outcome Measures

Primary Outcomes (1)

  • ratio of complete response

    complete response is defined as no retching or vomiting and no secondary rescue antiemetic administration

    24 hours after administration of study drug

Secondary Outcomes (1)

  • incidence of nausea and vomiting

    24 hours after administration of study drug

Study Arms (2)

Ondansetron group

ACTIVE COMPARATOR
Drug: Ondansetron

Ramosetron group

EXPERIMENTAL
Drug: Ramosetron

Interventions

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.

Ondansetron group

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.

Eligibility Criteria

Age19 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • age 19-65 years
