combination dosage forms of naproxen sodium and pseudoephedrine hydrochloride are used for symptomatic treatment of cold and sinus disorders. in this study, fourth-order derivative spectrophotometric method was used for simultaneous determination of naproxen sodium and pseudoephedrine hydrochloride. the method was linear over the range of 2-28 μg/ml for pseudoephedrine hydrochloride and 4-200 μ...

Inflammatory processes play a critical role in the pathogenesis of the neurodegenerative disorders and are associated with cognitive impairments. Nonsteroidal anti-inflammatory drugs (NSAIDs) and nitric oxide releasing NSAIDs are reported to be effective in reducing the risk of developing AD or cognitive impairments. Present experiments were performed to study the possible effect of nitro napro...

Bacteria were enriched from soil samples with succinate as a carbon source and racemic naproxen nitrile [2-(6-methoxy-2-naphthyl)propionitrile] as sole source of nitrogen. Since naproxen nitrile was only poorly soluble in water media amended with different water-immiscible organic phases were used for the enrichments. With pristane (2,6,10,14-tetramethylpentadecane) as the organic phase two bac...

Nonsteroidal anti-inflammatory drugs (NSAID) have been highly effective in preventing colon, urinary bladder, and skin cancer preclinically, and also in clinical trials of colon adenoma formation. However, certain NSAIDs cause gastrointestinal ulceration and may increase cardiovascular events. Naproxen seems to cause the lowest cardiovascular events of the common NSAIDs other than aspirin. Nitr...

Naproxen sodium (NAS) is a non-steroidal anti-inflammatory drug used to relieve moderate to severe aches and pains (1-3). Most of its therapeutic activity is probably mediated through prostaglandin synthesis inhibition (1,4,5). Once dissolved in biologic fluids, naproxen and NAS are chemically identical species and have the same biologic properties. Administration of naproxen as the sodium salt...

The small intestine is a significant site of ulceration and bleeding induced by nonsteroidal anti-inflammatory drugs (NSAIDs). The pathogenesis is poorly understood. The present study explored the roles of bile, bacteria, and enterohepatic circulation to NSAID enteropathy, using both a conventional NSAID (naproxen) and a gastrointestinal-safe naproxen derivative (ATB-346), as well as proton pum...

The possibility of applying liposomes as a topical drug delivery system is still a matter of intensive research. The purpose of this study was to determine the suitability of liposomes as carriers of naproxen and to prove their impact on the effectiveness of transdermal permeation of an active substance. The study was conducted with the use of Franz Diffusion Cell System by comparing the effica...

introduction : one of the most significant concerns after third molar surgery is the post-surgical dental pain. regarding the efficacy of the novafen and naproxen in pain control treatment, it is important to compare the effect of each of these medications to decide which one should be used. aim: the aim of this study was to compare the effect of novafen and naproxen on pain management in patie...

In this double-blind crossover trial, naproxen (750 mg/day) was compared to placebo for the treatment of osteoarthrosis of the hip and knee. Patients were randomly assigned to treatment with either naproxen or placebo for 4 weeks and then to treatment with the alternate agent for a second 4-week period. 8 out of 9 objective and subjective measurements of drug efficacy clearly differentiated nap...
