Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single-Dose Oral Pregabalin and Intravenous Ibuprofen Combination Administration before oral surgery. The treatment groups included the following: (Group 1) premedicated with oral placebo and intravenous (IV) placebo, (Group 2) premedicated with oral placebo and 400 mg IV Ibuprofen, (Group 3) premedicated with 75 mg oral pregabalin and 400 mg IV ibuprofen, and (Group 4) premedicated with 150 mg oral pregabalin and 400 mg IV ibuprofen.
Oral pregabalin (75 or 150 mg) (Lyrica; Pfizer, Inc., New York, NY) and oral placebo (using similar looking cornstarch capsules) were administered to the corresponding treatment groups one hour before surgery. Intravenous ibuprofen (400 mg) (Intrafen; Gen Pharmaceuticals, Istanbul, Turkey) and intravenous placebo (sterile saline solution) were administered via intravenous infusion 30 minutes before surgery

The medications were administered by a nurse who supervised by the director of the department, from the oral and maxillofacial surgery department.

Outcomes
Primary outcome [1] 306150 0
The primary outcome measured was postoperative pain levels;
All subjects were instructed to rate the severity of their pain using a horizontal, plain 100-mm length visual analog scale (VAS) with anchors of “no pain” on one side and “worst pain imaginable” on the other.
Timepoint [1] 306150 0
Postoperative pain was assessed every hour for the first 12 hours following surgery. Pain was then assessed at 8, 12, 16, and 20 h during the second and third days and at 12 h during the fourth, fifth and sixth postoperative days.

Patients were instructed to record their pain on VAS in the mentioned time intervals
Secondary outcome [1] 347799 0
the nonnarcotic analgesic requirement ( number of nonnarcotic analgesic tablets required by patients during postoperative 6 days) We recorded the time when the surgery finished and
patients has a postoperative logbook .The patients recorded the time of first analgesic request after surgery and the number of tablets consumed. After 6 days we collected all logbooks and calculated the data .
Timepoint [1] 347799 0
6 days post commencement of intervention
Secondary outcome [2] 347800 0
the first rescue analgesic request time (The duration of first analgesic need after surgery)
We recorded the time when the surgery finished and patients has a postoperative logbook .The patients recorded the time of first analgesic request after surgery and the number of tablets consumed. After 6 days we collected all logbooks and calculated the data .
Timepoint [2] 347800 0
During first 24 hour after the end of intervention

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients were assigned to one of the four treatment arms using randomized computer-generated numbers (generated in www. randomizer. org). Ninety opaque coded envelopes bearing serial numbers for the four treatment arms were prepared. A nurse, who was not part of the study, prepared the envelopes and performed the group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software

Efficacy
Statistical methods / analysis
IBM SPSS Statistics Standard Grad Pack version 22.0 for Windows (IBM Corporation, Armonk, NY licensed from Ataturk University, Erzurum, Turkey) was used for the statistical analyses. The normality of the quantitative data distribution was evaluated using the Shapiro-Wilk test. Kruskal-Wallis tests were used to compare the four groups in terms of the duration of the surgical procedure, surgical difficulty, intensity of the postoperative pain (VAS scores) at different time intervals, analgesic consumption, and first rescue analgesic request time after surgery. The demographic data and complications related to the medications were analyzed using Chi-square' tests.

Summary
Brief summary
We hypothesise that preoperative coadministration of ibuprofen and pregabalin combination is resulted better pain control than preoperative placebo or same dose of sole ibuprofen
The objective of this study was to compare the efficacy of pregabalin and intravenous ibuprofen with regard to pain management and analgesic consumption after third molar surgery. Materials and methods: This was a prospective, randomized, controlled, double-blind study. Eighty patients who had planned for surgical extraction of impacted third molars were included in the study. The treatment groups included the following: (Group 1) premedicated with oral placebo and intravenous (IV) placebo, (Group 2) premedicated with oral placebo and 400 mg IV Ibuprofen, (Group 3) premedicated with 75 mg oral pregabalin and 400 mg IV ibuprofen, and (Group 4) premedicated with 150 mg oral pregabalin and 400 mg IV ibuprofen. The primary outcome measured was postoperative pain levels; secondary outcomes included the nonnarcotic analgesic requirement and the first rescue analgesic request time. The ratio of male/female participants, age, side effects, surgery difficulty, and duration of surgery were also evaluated.
