Filter by:The purpose of this study is to perform a randomized, double blind 4-arm clinical trial of the comparative efficacy of 4 oral analgesics in the initial management of acute musculoskeletal extremity pain presenting to the ED.
This is a randomized, double-blind, placebo-controlled, two-arm parallel, single-center study. One hundred subjects (50 in each arm) will be enrolled. Subjects, between the ages 18 and 65, undergoing laparoscopic gastric bypass or sleeve gastrectomy will be recruited and consented during the preadmission visit prior to surgery.
Pharmacogenetics is an area of Pharmacology that studies the contribution of genetic factors to individual responses to drugs. This branch of science involves the variability in pharmacodynamics and pharmacokinetics through the study of polymorphisms in genes encoding receptors, as well as in drug metabolism, where this area of Pharmacology has been growing and achieving its first results with clinical use. The non-steroidal anti-inflammatory (NSAIDS) are metabolized by cytochrome P450 (CYP) family, predominantly CYP2C9. The goal of this study is to evaluate the different gene haplotypes for the clinical efficacy of piroxicam after third lower molar surgery for pain, edema and trismus, adverse reactions, need of rescue medication, patient satisfaction regarding the drug and the pharmacokinetics of the drug between the different gene haplotypes for CYP2C9 that are found in this population. Therefore, 60 patients will be genotyped and phenotyped for this gene and their postoperative data will be confronted with the data found in the Brazilian population. For the analysis of the proposed gene, saliva will be collected and serve as a source of genomic DNA. For the molecular analysis, polymerase chain reaction (PCR) with tests validated and produced by Applied Biosystems® will be performed. For the pharmacokinetics, saliva samples will be collected at various times according to protocols available in the literature, and piroxicam concentrations in the samples will be measured by high pressure liquid chromatography (HPLC) and Liquid chromatography-mass spectrometry (LC MS/MS). The analysis of the results will be described with a significance level of 0.05.
To determine whether three new oral formulations of a strong pain killer release the drug into the body in a similar pattern as the already marketed reference capsule formulation with or without food
This study is to evaluate the relative bioavailability of nalbuphine after single IM injection of Sebacoyl Dinalbuphine Ester (SDE) injection and Bain®, Nalbuphine HCl IM injection in healthy volunteers.
The purpose of the study is to examine if the hyposthesis of the preventive analgestic characteristic of diclofenac given preoperatively has any effect on postoperative thoracic wall and shoulder pain sensation. We also want to examine the rescue analgetic consumption and the postoperative lung function test values.
This randomized clinical trial studies aromatherapy and essential oils in improving insomnia and other symptoms in patients with newly diagnosed acute leukemia. Aromatherapy and essential oils may help improve insomnia and other complications caused by chemotherapy.
The purpose of this prospective, randomized, double-blind study was to compare the prospective pain in asymptomatic mandibular molar teeth with necrotic pulp and periapical lesion using three different instrumentation files: Hand, Protaper Universal, and Wave-One files.
This study aims to assess self reported procedural pain compared with background pain and evaluate pain intensity differences across six standard procedures. Besides, rescue and preventive treatments used to control procedural pain will be examined.
Intranasal hydromorphone has been shown to be effective in reducing acute pain in adults. It has not been previously studied in children, but may be a viable option for effectively and safely reducing pain in children by administering an analgesic by the intranasal route. This study will be a prospective, open-label pilot study of intranasal hydromorphone in children with moderate to severe acute pain presenting to the pediatric emergency department. The investigators aim to describe the amount of pain reduction associated with intranasal hydromorphone, and to determine the optimal dose of intranasal hydromorphone associated with a clinically meaningful improvement in acute pain.
