Interaction Between Tramadol and Ondansetron
Overview
In the postoperative period; pain, nausea, and vomiting are undesirable side effects that reduce the patient's comfort and may lead to various complications. Ondansetron is frequently used as an antiemetic and tramadol hydrochloride is used for postoperative analgesia in laparoscopic cholecystectomy. However, some studies have reported that there is a drug interaction between these two drugs and they reduce each other's effects, thus requiring more analgesics in the postoperative period. The aim of this study is; To evaluate whether ondansetron reduces the analgesic efficacy of tramadol hydrochloride in laparoscopic cholecystectomies.

Study Type
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Factorial Assignment
- Primary Purpose: Health Services Research
- Masking: Double (Participant, Investigator)
- Study Primary Completion Date: June 25, 2021
Detailed Description
During the operation, 4 mg iv ondansetron (2mL) will be administered to the ondansetron group and 2mL iv 09% saline will be administered to the placebo group. The patients' heart rate, blood pressure, oxygen saturation, sedation score (with Ramsey Seading Score), amount of pain (with NRS), degree of nausea (with NRS), whether there is vomiting, whether analgesic or antiemetic treatment is required, and the amount of tramadol use will be recorded at 1, 2, 4, 8, 12 and 24 hours in the postoperative period.
Interventions
- Drug: Ondansetron 4 MG (Kemoset 4mg)
- Ondansetron 4mg (iv) will administer to participants
- Other: Salin solution
- Salin solution 2ml (iv) will administer to participants
Arms, Groups and Cohorts
- Active Comparator: Ondansetron
- Participants will receive Kemoset 4 mg iv intraoperatively
- Placebo Comparator: Salin solution
- Participants will receive Salin solution 2ml (iv) intraoperatively
Clinical Trial Outcome Measures
Primary Measures
- Interaction
- Time Frame: 24 hours
- The hypothesis of this study is that if ondanstron is given together with tramadol peroperatively, tramadol consumption is increase postoperatively due to tramadol ondansetron interaction. The primary outcome measure is consumption of tramadol postoperatively for 24 hours.
