We hypothesize that the combination of aprepitant with dexamethasone will provide significantly improved prophylaxis against Postoperative nausea and vomiting compared with the combination of ondansetron and dexamethasone, in patients undergoing craniotomy under general anesthesia.

Condition Intervention Phase

Drug: Aprepitant + Dexamethasone
Drug: Ondansetron + Dexamethasone

Primary Outcome Measures:
  • Cumulative Incidence of Emesis [ Time Frame: 48 h ] [ Designated as safety issue: No ]
    Any vomiting or retching

Secondary Outcome Measures:
  • Incidence of Nausea [ Time Frame: Post operative procedure (OP) hours (0-2, 24, 48) ] [ Designated as safety issue: No ]
    operative procedure

  • Incidence of Vomiting [ Time Frame: Post OP (0 - 2 hours) ] [ Designated as safety issue: No ]
  • Incidence of Vomiting [ Time Frame: 24 h ] [ Designated as safety issue: No ]
    Any vomiting or retching

  • Use of Rescue Antiemetics [ Time Frame: Post OP (0 - 2 hours) ] [ Designated as safety issue: No ]
  • Use of Rescue Antiemetics [ Time Frame: 24 h ] [ Designated as safety issue: No ]
  • Use of Rescue Antiemetics [ Time Frame: 48 hour ] [ Designated as safety issue: No ]
  • Number of Participants With a Complete Response Rate [ Time Frame: 24 hours Post OP, 48 hours Post OP ] [ Designated as safety issue: No ]
    complete response rate: defined as no Postoperative nausea and vomiting (PONV) and no need for rescue antiemetics.

  • Average Nausea Score [ Time Frame: Post OP hours 0-2, 24 h, 48 h ] [ Designated as safety issue: No ]
    Participants verbally rated their nausea on a scale of 0-10. 0 = No nausea, 10 = worst nausea imaginable

  • Number of Vomiting Episodes [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
  • Time to First Vomiting [ Time Frame: 48 h ] [ Designated as safety issue: No ]
  • Number of Participants Who Rated Their Satisfaction With Antiemetic Management as "Very Satisfied" [ Time Frame: 48 hour ] [ Designated as safety issue: No ]
    Participants rated their satisfaction with antiemetic management on a 5 points scale: very satisfied, somewhat satisfied, neither satisfied nor dissatisfied, somewhat dissatisfied, very dissatisfied)

Exclusion Criteria:

A patient will not be eligible for inclusion in this study if any one or more of the following criteria apply within thirty days of patient enrollment in this clinical trial:

  • Medical: Any condition that may impair a patient's ability to complete any of the study assessments or confound interpretation of results.
  • Hypersensitivity: Patient has a known immediate or delayed hypersensitivity reaction or known idiosyncrasy to any of the two study medications, ondansetron, or aprepitant.
  • Other Drugs: Patients should not be taking medications with known antiemetic properties (phenothiazines, butyrophenones, antihistamines), nor should they receive metoclopramide, or other antiemetics preoperatively or 12 hours before the scheduled surgical procedure.
  • Pregnant or lactating females: A pregnancy test will be performed within 24 hours of entering the study for females of childbearing potential.
