Comparison of the Clinical Efficacy of Ketoprofen, Associated or Not With Omeprazole in Lower Third Molar Removal

Pain Clinical Trial

Official title: Comparison of the Clinical Efficacy of Ketoprofen, Associated or Not With Omeprazole, in the Control of Pain, Swelling and Trismus in Lower Third Molar Removal

Status Completed

Clinical Trial Summary

The control of pain, swelling and trismus in patients undergoing oral and maxillofacial surgery is frequently performed through the administration of non-steroidal anti-inflammatory drugs (NSAIDS). The present study aims to evaluate in a double blind, randomized and crossover manner the clinical efficacy of ketoprofen (immediate release - 100 mg) and ketoprofen in association with omeprazole (modified release - 200 mg ketoprofen with 20 mg omeprazole) in 50 patients aged 18 years or older that require removal of both lower third molars symmetrically positioned. After collection, data will be analyzed by means of graphs and tables to allow the appropriate analyses. Paired t-test will be used to compare the duration of surgeries. Nonparametric Wilcoxon test will be used for the analysis of "rescue medication" and postoperative pain parameters (visual analog scale). Data of "mouth opening" and "swelling" will be statistically analyzed through analysis of variance (ANOVA) followed by Tukey's test for multiple comparisons. Statistical significance will be set at 5%. Results will be presented as mean ± standard deviation of the mean.

Clinical Trial Description

Studies have shown that NSAIDS exert their therapeutic effect by the inhibition of cyclooxigenases (COX) 1 and 2, which determines the inhibition of prostaglandins production whose effects potentiate the action of many inflammatory mediators. The protocol for the administration of these formulations will involve the administration of a tablet of the immediate release product (100 mg) every 12 hours, and one capsule of the modified release product (200 mg ketoprofen with omeprazole) every 24 hours, during 4 days.

The following parameters will be analyzed:

1. subjective postoperative pain evaluation, with the aid of a visual analogue scale,

2. mouth opening before the surgery, on the 2nd and 7th postoperative days (moment of suture removal),

3. beginning and duration of the surgery after anesthetic administration,

4. incidence, type and severity of adverse reactions,

5. total amount of rescue analgesic medication (paracetamol),

6. facial swelling measured on the 2nd and 7th postoperative days (in comparison with the measurements before the surgery). ;
