Study on the Consumption of Non-Steroidal Anti-Inflammatory Drugs and Antibiotics by the Brazilian Adult Population: A Cohort Study.

Self-medication without a medical or dental prescription is an action that leads to a significant problems associated with the overuse of medication in Brazil. The inappropriate use of antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) leads to problems related to microbial agent resistance and gastrointestinal complications. The purpose of this study was to elucidate the patterns of antibiotic and NSAIDs consumption among the adult population of Brazil.

Liquid Chromatography-Tandem Mass Spectrometry Method for Detection and Quantification of Meloxicam and 5'-Carboxymeloxicam in Oral Fluid Samples.

Multifocal Analysis of Acute Pain After Third Molar Removal.

To analyze the pain modulation capacity profile in a Brazilian population, the relationship between opioid receptor () and Catechol-O-methyltransferase () 1polymorphisms and pain modulation capacity was determined through preoperative pain modulation tests and acute postoperative pain control evaluation, swelling, and trismus in 200 volunteers undergoing lower third molar removal. Psychologic and clinical parameters were measured. Patient DNA was sequenced for single nucleotide polymorphisms in and , and the salivary concentration of interleukin (IL)-2 (IL)-6, interferon (IFN)-γ and tumor necrosis factor (TNF)-α was evaluated.

CYP450 polymorphisms and clinical pharmacogenetics of ibuprofen after lower third molar extraction.

Purpose: This study hypothesized that drugs accumulate in the bloodstream of poor-metabolizing patients and may have more adverse effects and different pain perceptions and aimed to investigate the influence of CYP450 polymorphisms on acute postoperative pain, swelling, and trismus controlled by ibuprofen (600 mg) in 200 volunteers after dental extraction. In addition, surgical outcomes can determine pain, edema, and trismus and indicate inflammatory reactions after oral surgeries.

Methods: Genetic sequencing was performed to identify CYP450 polymorphisms and the surgical parameters evaluated: pre and postoperative swelling, trismus, and temperature; self-reported postoperative pain with visual analog scale (VAS); rescue medication consumed; and severity of adverse reactions.

Simultaneous separation of naproxen and 6-O-desmethylnaproxen metabolite in saliva samples by liquid chromatography-tandem mass spectrometry: Pharmacokinetic study of naproxen alone and associated with esomeprazole.

Naproxen is a widely used non-steroidal anti-inflammatory drug for the control of postoperative inflammatory signs and symptoms in dentistry. Its association with esomeprazole has been widely studied and has yielded good results for the control of acute pain, even with the delayed absorption of naproxen owing to the presence of esomeprazole. To further understand the absorption, distribution, and metabolism of this drug alone and in combination with esomeprazole, we will analyze the pharmacokinetic parameters of naproxen and its major metabolite, 6-O-desmethylnaproxen, in saliva samples.
