1. Simultaneous determination of non-steroidal anti-inflammatory drugs in pharmaceutical formulations and human serum by reversed phase high performance liquid chromatography
A rapid and sensitive method using high performance liquid chromatography has been developed and validated for the simultaneous determination of non-steroidal anti-inflammatory drugs (NSAIDs) in pharmaceutical formulations and human serum. Six NSAIDs including: naproxen sodium, diclofenac sodium, meloxicam, flurbiprofen, tiaprofenic and mefenamic acid were a

2. Thermodynamic study of the solubility of sodium naproxen in some ethanol + water mixtures
By using the van't Hoff and Gibbs equations the apparent thermodynamic functions Gibbs energy, enthalpy, and entropy of solution for sodium naproxen in ethanol + water cosolvent mixtures, were evaluated from solubility data determined at temperatures from (278.15 to 308.15) K. The drug solubility was greatest in neat water and lowest in neat ethanol at all t

3. Naproxeno sódico diminui a recorrência da migrânea quando administrado com o sumatriptan
Quarenta a 78% dos pacientes que utilizam sumatriptan para o tratamento agudo das migrâneas ou enxaquecas apresentam recorrência pelo menos ocasionalmente. O uso concomitante de um anti-inflamatório não esteroidal (AINE) tem sido recomendado para reduzir a frequência da recorrência. Sessenta e sete pacientes que haviam tratado com sucesso pelo menos 8

4. Effect of hydroxypropyl methylcellulose and hydrogenated castor oil on naproxen release from sustained-release tablets
The effect of the concentration of hydrophilic (hydroxypropyl methylcellulose [HPMC]) and hydrophobic (hydrogenated castor oil [HCO]) products, fillers (lactose and dibasic calcium phosphate), and buffers (sodium bicarbonate, calcium carbonate, and sodium citrate) on naproxen release rate was studied. Matrix tablets were prepared by double compression, andIn

5. Naproxen sodium, diflunisal, and placebo in the treatment of chronic back pain.
Thirty-seven patients with chronic back pain were entered into a randomised, 3-way, double-blind, cross-over comparison of naproxen sodium 550 mg twice daily, diflunisal 500 mg twice daily, and placebo. Each treatment was given for 14 days after a preadmission wash-out week during which only paracetamol was allowed. Patients were assessed on admission and at

6. Double-blind comparison of efficacy and gastroduodenal safety of diclofenac/misoprostol, piroxicam, and naproxen in the treatment of osteoarthritis.
OBJECTIVES--To compare the efficacy and gastroduodenal safety of a fixed-dose combination of diclofenac sodium 50 mg and misoprostol 200 micrograms twice daily with those of piroxicam 10 mg twice daily and naproxen 375 mg twice daily in patients with osteoarthritis. METHODS--A 4 week, randomised, double-blind, parallel-group, multicentre study was conducted

7. Effect of oppositely charged polymer and dissolution medium on swelling, erosion, and drug release from chitosan matrices
The purpose of this research was to investigate the potential use of anionick-carrageenan and nonionic hydroxypropyl-methylcellulose (HPMC, K4) to improve the matrix integrity of directly compressed chitosan tablets containing naproxen sodium, an anionic drug. The influence of buffer pH and drug:polymer ratio on the water uptake, matrix erosion, and drug rel

8. Physicomechanical Properties of Naproxen-Loaded Microparticles Prepared from Eudragit L100
Microparticles of naproxen with Eudragit L100 and Aerosil were prepared by the emulsion solvent diffusion method in order to avoid local gastrointestinal irritation, one of the major side effects of nonsteroidal anti-inflammatory drugs after oral ingestion. The process of preparation involved the use of ethanol as good solvent, dichloromethane as a bridging

9. The Drug of Abuse γ-Hydroxybutyrate Is a Substrate for Sodium-Coupled Monocarboxylate Transporter (SMCT) 1 (SLC5A8): Characterization of SMCT-Mediated Uptake and Inhibition
γ-Hydroxybutyric acid (GHB), a drug of abuse, is a substrate of monocarboxylate transporters (MCTs). Sodium-coupled monocarboxylate transporter 1 (SMCT1; SLC5A8) is expressed in kidney, thyroid gland, neurons, and intestinal tract and exhibits substrate specificity similar to that of the proton-dependent MCT (SLC16A) family. The role of SMCT1 in GHB dis

10. Arachidonate metabolism via lipoxygenase and 12L-hydroperoxy-5,8,10,14-icosatetraenoic acid peroxidase sensitive to anti-inflammatory drugs.
The enzymes of arachidonate metabolism via the lipoxygenase pathway in human platelet cytosol have been characterized and partially purified. The lipoxygenase activity has a pH optimum of 7.3 and reaches half-maximal activity at an arachidonate concentration of 80 microM. The oxidation of arachidonate by these enzymes is inhibited by reagents that modify sul

11. Quantitative analysis of walking in patients with knee osteoarthritis: a method of assessing the effectiveness of non-steroidal anti-inflammatory treatment.
Most therapeutic tests of osteoarthritis treatments are assessed by criteria based either on fundamental data or on clinical data, which is often subjective. A quantified analysis of locomotion can be used to determine the spatiotemporal indices (stride length and duration), kinematic indices (walking speed, velocity peak), and symmetry criteria that are rel

12. Selectivity of nonsteroidal antiinflammatory drugs as inhibitors of constitutive and inducible cyclooxygenase.
Constitutive cyclooxygenase (COX-1; prostaglandin-endoperoxide synthase, EC 1.14.99.1) is present in cells under physiological conditions, whereas COX-2 is induced by some cytokines, mitogens, and endotoxin presumably in pathological conditions, such as inflammation. Therefore, we have assessed the relative inhibitory effects of some nonsteroidal antiinflamm
