Because of numerous indications and high availability, non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly prescribed and used medicines in the world. However, long-term therapy with and improper use of NSAIDs may lead to gastrointestinal damage. Therefore, improving the therapeutic index of the existing drugs has become a priority over the past decades. Considerable attention in the field has been concentrated on metal complexes of non-steroidal anti-inflammatory drugs. The aim of this study is to evaluate the effect of complexation with zinc on the anti-inflammatory and ulcerogenic effects of ibuprofen and naproxen after single and triple intragastric administration to rats...

Till now, no attention has been paid to pharmaceuticals (PCs) in the air, though they are known to affect waters, soils, foods and biota. This paper describes the first attempt to characterize the PC occurrence in the air. Airborne particulates (PM10 or PM2.5 fractions, from Amsterdam, Netherland, Rome and Rende, Italy) were sampled on quartz fiber filter by means of pumping systems operating at medium-volume conditions (16 or 38.5 L min(-1)). The samples were solvent extracted through sonication with a dichloromethane:acetone:methanol mixture and reduced close to dryness; three fractions of the residue were separated through column chromatography; they comprised non polar, low polar and very polar organic compounds, respectively, and PCs were in the third one...

BACKGROUND: Osteoarthritis (OA) is the most common form of arthritis and is caused by degeneration of the joint cartilage and growth of new bone, cartilage and connective tissue. It is often associated with major disability and impaired quality of life. There is currently no consensus on the best treatment to improve OA symptoms. Celecoxib is a selective non-steroidal anti-inflammatory drug (NSAID). OBJECTIVES: To assess the clinical benefits (pain, function, quality of life) and safety (withdrawals due to adverse effects, serious adverse effects, overall discontinuation rates) of celecoxib in osteoarthritis (OA)...

Agricultural use of treated wastewater, biosolids and animal wastes introduces a multitude of contaminants of emerging concerns (CECs) into the soil-plant system. The potential for food crops to accumulate CECs depends largely on their metabolism in plants, which at present is poorly understood. Here we evaluated the metabolism of naproxen and ibuprofen, two of the most used human drugs from the profen family, in Arabidopsis thaliana cells and Arabidopsis plant. The complementary use of high-resolution mass spectrometry and 14C labeling allowed characterization of both free and conjugated metabolites, as well as non-extractable residues...

The inclusion complexes of a new family of nonionic amphiphilic calix[4]arenes with the anti-inflammatory hydrophobic drugs naproxen (NAP) and ibuprofen (IBP) were investigated. The effects of the alkyl chain's length and the inner core of calix[4]arenes on the interaction of the two drugs with the calix[4]arenes were explored. The inclusion complexes of Amphiphiles 1a-c with NAP and IBP increased the solubility of these drugs in aqueous media. The interaction of 1a-c with the drugs in aqueous media was investigated through fluorescence, molecular modeling, and ¹H-NMR analysis...

Various ternary Guest 2/(Guest 1/γ-cyclodextrin (CD)) complexes were prepared using a cogrinding and subsequent heating method, wherein Guest 1 was incorporated in the cavity of γ-CD and Guest 2 was incorporated into the intermolecular spaces between γ-CD columns. Dissolution fluxes of Guest 1 and Guest 2 from all ternary complexes were almost identical. The dissolution flux of flurbiprofen (Guest 1) from the ternary complexes depended on the solubility of Guest 2 drugs (naproxen < ketoprofen < ethenzamide) in the dissolution medium of pH 1...

BACKGROUND: There is a need for better joint pain treatment, but development of new medication has not been successful. Pre-clinical models with readouts that better reflect the clinical situation are needed. In patients with joint pain, pain at rest and pain at walking are two major complaints. NEW METHOD: We describe a new way of calculating results from gait analysis using the CatWalk™ setup. Rats with monoarthritis induced by injection of Complete Freund's Adjuvant (CFA) intra-articularly into the ankle joint of one hind limb were used to assess gait and dynamic weight bearing...

Naproxen is one of the most prevalent pharmaceuticals and of great environment concern. Information about bioremediation of naproxen by algae remains limited and no study has been reported on the degradation mechanism and the toxicity of NPX on algae. In this study, both Cymbella sp. and Scenedesmus quadricauda showed complete growth inhibition (100%) at 100mgL(-1) within 24h. Biochemical characteristics including chlorophyll a, carotenoid contents and enzyme activities for these two microalgae were affected by NPX at relatively high concentrations after 4d of exposure...

S-naproxen by enantioselective hydrolysis of racemic naproxen methyl ester was produced using immobilized lipase. The lipase enzyme was immobilized on chitosan beads, activated chitosan beads by glutaraldehyde, and Amberlite XAD7. In order to find an appropriate support for the hydrolysis reaction of racemic naproxen methyl ester, the conversion and enantioselectivity for all carriers were compared. In addition, effects of the volumetric ratio of two phases in different organic solvents, addition of cosolvent and surfactant, optimum pH and temperature, reusability, and inhibitory effect of methanol were investigated...

A 38-year-old woman was referred to our hospital with pelvic inflammatory disease. She had been diagnosed as having a tubo-ovarian abscess, for which antibiotic therapy with metronidazole and levofloxacin was indicated. Because the patient was already taking lithium she was prescribed clindamycin instead of metronidazole, a drug that interacts with lithium. For the same reason, naproxen could not be prescribed to reduce pain. However, the lithium taken by the patient turned out to be a dietary supplement containing lithium orotate which she had obtained via the Internet...
