Analgesic Efficacy of a New Immediate ‐Release/Extended‐Release Formulation of Ibuprofen: Results From Single‐ and Multiple‐Dose Postsurgical Dental Pain Studies
Abstract Analgesic effects of ibuprofen immediate‐release/extended‐release (IR/ER) 600‐mg tablets were evaluated in 2 randomized, double‐blind, placebo‐controlled dental pain studies. Patients 16–40 years old with moderate–severe pain following third‐molar extraction received single‐dose ibuprofen 600 mg IR/ER (formulation A or B), naproxen sodium 220 mg, or placebo (2:2:2:1; study 1) or 4 doses of ibuprofen 600 mg IR/ER (formulation A) or placebo (1:1; study 2). In study 1 (n = 196), mean (standard deviation [SD]) time‐weighted sum of pain intensity difference scores for placebo, ibuprofen IR/ER A, ibu...

Pharmacokinetic profile of extended-release versus immediate-release oral naproxen sodium after single and multiple dosing under fed and fasting conditions: two randomized, open-label trials.
CONCLUSIONS: The total exposure of ER naproxen sodium (660 mg) is comparable to IR naproxen sodium (220 mg) when administered at the maximum over the counter (OTC) dose of 660-mg daily dose on a single day and over multiple days. The rate of absorption is delayed under fed conditions. PMID: 27639137 [PubMed - as supplied by publisher] (Source: International Journal of Clinical Pharmacology and Therapeutics)

Naproxen sodium for pain control with intrauterine device insertion: a randomized controlled trial
Objectives: Prior studies of naproxen sodium suggest effective pain relief with IUD insertion. It is unclear if these results apply to modern T-shaped IUDs. We hypothesized that 550 mg of oral naproxen sodium 1 h prior to IUD insertion would reduce pain compared with placebo. (Source: Contraception)

Newly Approved Agents for the Treatment and Prevention of Pediatric Migraine
AbstractTreatment of pediatric migraine remains an unmet medical need. There continues to be a paucity of pediatric randomized controlled trials for the treatment of migraine, both in the acute and preventive settings. Pediatric studies are often complicated by high placebo-response rates and much of our current practice is based on adult trials. This lack of significant pediatric studies results in a wide variation in migraine management both amongst clinicians and between institutions, and evidence-based treatments are not always administered. In this article, we aim to briefly review newly approved abortive and preventi...

Case Report: Industrial X-Ray Injury Treated With Non-Cultured Autologous Adipose-Derived Stromal Vascular Fraction (SVF)
Abstract: Local cutaneous injuries induced by ionizing radiation (IR) are difficult to treat. Many have reported local injection of adipose-derived stromal vascular fraction (SVF), often with additional therapies, as an effective treatment of IR-induced injury even after other local therapies have failed. The authors report a case of a locally recurrent, IR-induced wound that was treated with autologous, non-cultured SVF without other concurrent therapy. A nondestructive testing technician was exposed to 130 kVp x rays to his non-dominant right thumb on 5 October 2011. The wound healed 4 mo after initial conservative thera...

Drugs for the acute treatment of migraine in children and adolescents.
CONCLUSIONS: Low quality evidence from two small trials shows that ibuprofen appears to improve pain freedom for the acute treatment of children with migraine. We have only limited information on adverse events associated with ibuprofen in the trials included in this review. Triptans as a class are also effective at providing pain freedom in children and adolescents but are associated with higher rates of minor adverse events. Sumatriptan plus naproxen sodium is also effective in treating adolescents with migraine. PMID: 27091010 [PubMed - as supplied by publisher] (Source: Cochrane Database of Systematic Reviews)

Molecules, Vol. 21, Pages 509: Properties of the Sodium Naproxen-Lactose-Tetrahydrate Co-Crystal upon Processing and Storage
In this study, the behavior of the recently identified sodium naproxen-lactose-tetrahydrate co-crystal and the co-amorphous mixture of sodium, naproxen, and lactose was investigated. The structure of the co-crystal is described using single-crystal X-ray diffraction. The structural analysis revealed a monoclinic lattice, space group P21, with the asymmetric unit containing one molecule of lactose, one of naproxen, sodium, and four water molecules. Upon heating, it was observed that the co-crystal transforms into a co-amorphous system due to the loss of its crystalline bound water. Dehydration and co-amorphization were stud...

Different effects of the nonsteroidal anti-inflammatory drugs meclofenamate sodium and naproxen sodium on proteasome activity in cardiac cells
The use of nonsteroidal anti-inflammatory drugs (NSAIDs) like meclofenamate sodium (MS), used to reduce pain, has been associated with an increased risk of cardiovascular disease (CVD). Naproxen (NAP), another NSAID, is not associated with increased risk of CVD. The molecular mechanism(s) by which NSAIDs induce CVD is unknown.We investigated the effects of MS and NAP on protein homeostasis and cardiotoxicity in rat cardiac H9c2 cells and murine neonatal cardiomyocytes.MS, but not NAP, significantly inhibited proteasome activity and reduced cardiac cell viability at pharmacological levels found in humans.

Development and validation of an LC-ESI-MS/MS method for the simultaneous quantification of naproxen and sumatriptan in human plasma: application to a pharmacokinetic study.
Abstract A sensitive and fast liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) method was developed and validated for the simultaneous quantification of naproxen and sumatriptan in human plasma. A simple liquid-liquid extraction procedure, with a mixture of ethyl acetate, methyl tert-butyl ether, and dichloromethane (4:3:3, v/v), was used for the cleanup of plasma. Naratriptan and aceclofenac were employed as internal standards. The analyses were carried out using an ACE C18 column (50 × 4.6 mm i.d.; particle size 5 μm) and a mobile phase consisting of 2 mM aqu...

Efficacy of single-dose, extended-release naproxen sodium 660 mg in postsurgical dental pain: two double-blind, randomized, placebo-controlled trials.
CONCLUSIONS: A single dose of ER naproxen sodium 660 mg significantly reduced moderate to severe dental pain vs. placebo and was comparable to IR naproxen sodium 220 mg tid. Significant pain relief was experienced from 15 min and sustained over 24 h, resulting in a reduced need for rescue medication. ER naproxen sodium 660 mg once daily is a convenient and effective therapy providing 24 h relief of pain. PMID: 26588111 [PubMed - in process] (Source: Current Medical Research and Opinion)

A High-Performance Thin Layer Chromatography (HPTLC) Method for Simultaneous Determination of Diphenhydramine Hydrochloride and Naproxen Sodium in Tablets.
Abstract A rapid and simple high-performance thin layer chromatography (HPTLC) method with densitometry at 230 nm was developed and validated for simultaneous determination of diphenhydramine hydrochloride (DPH) and naproxen sodium (NPS) from pharmaceutical preparation. The separation was carried out on aluminum plates precoated with silica gel 60 F254 using mobile phase toluene:methanol:glacial acetic acid (7.5:1:0.2, v/v/v). The linearity range lies between 200 and 1200 ng/band for DPH and 1760 and 10,560 ng/band for NPS with correlation coefficients of 0.994 and 0.995, respectively. The R f value for DPH ...

Sumatriptan/Naproxen Sodium: A Review in Migraine
Abstract Sumatriptan/naproxen sodium (Treximet®) is a fixed-dose combination of a serotonin 5-HT1B/1D receptor agonist (sumatriptan) and an NSAID (naproxen sodium), approved in the USA for the acute treatment of migraine with or without aura in adolescents and adults. In a randomized, phase 3 trial in adolescents, significantly more sumatriptan/naproxen sodium than placebo recipients were pain-free at 2 h. Similarly, in a pair of randomized phase 3 trials in adults, significantly more sumatriptan/naproxen sodium than placebo recipients had relief from migraine symptoms at 2 h, and the combination was m...
