Evaluation of anti-inflammatory and ulcerogenic potential of zinc –ibuprofen and zinc–naproxen complexes in rats
AbstractBecause 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 ...

Celecoxib for osteoarthritis.
CONCLUSIONS: We are highly reserved about results due to pharmaceutical industry involvement and limited data. We were unable to obtain data from three studies, which included 15,539 participants, and classified as awaiting assessment. Current evidence indicates that celecoxib is slightly better than placebo and some tNSAIDs in reducing pain and improving physical function. We are uncertain if harms differ among celecoxib and placebo or tNSAIDs due to risk of bias, low quality evidence for many outcomes, and that some study authors and Pfizer declined to provide data from completed studies with large numbers of participant...

Enzymes Involved in Naproxen Degradation by Planococcus sp. S5.
Authors: Wojcieszyńska D, Domaradzka D, Hupert-Kocurek K, Guzik U Abstract Naproxen is a one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs) entering the environment as a result of high consumption. For this reason, there is an emerging need to recognize mechanisms of its degradation and enzymes engaged in this process. Planococcus sp. S5 is a gram positive strain able to degrade naproxen in monosubstrate culture (27%). However, naproxen is not a sufficient growth substrate for this strain. In the presence of benzoate, 4-hydroxybenzoic acid, 3,4-dihydroxybenzoic acid or vanillic acid as growth s...

Pharmaceutical substances in ambient particulates: A preliminary assessment.
Abstract 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...

[Confusion caused by dietary supplement lithium orotate].
Abstract 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. Because the serum lithium level pr...

Inhibition of pro-inflammatory enzymes by medicinal plants from the Argentinean highlands (Puna)
Conclusions Six out of the 13 species investigated showed a moderate to strong effect towards the enzyme sPLA2 (>40% inhibition at 200µg/mL) while three species presented strong activity against LOX with IC50< 250µg/mL and three were very active against hyaluronidase. Most of the crude drug extracts were able to stabilize the red blood cells membrane preventing their lysis. The compounds identified in the extracts can explain, at least in part, the activity found in the samples. The effect observed for the most active species support their traditional use as anti-inflammatory agents. However, more...

Coxibs Refocus Attention on the Cardiovascular Risks of Non-Aspirin NSAIDs
This article explains how coxibs refocused attention on the cardiovascular safety of NSAIDs and the general implications of that. COX-2 activity/specificity is one factor associated with increased cardiovascular risks; however, these risks cannot be attributed to coxibs alone. The traditional NSAIDs (i.e., meloxicam, etodolac, and nabumetone) have significant COX-2 specificity, but naproxen and ibuprofen have less specificity. All NSAIDs, whether traditional or a coxib, pose some cardiovascular risks. It is possible that clinicians continue to focus more on decreasing the immediate gastric risks than preventing the later c...

Oral nonsteroidal anti-inflammatory drugs for fibromyalgia in adults.
CONCLUSIONS: There is only a modest amount of very low-quality evidence about the use of NSAIDs in fibromyalgia, and that comes from small, largely inadequate studies with potential risk of bias. That bias would normally be to increase the apparent benefits of NSAIDs, but no such benefits were seen. Consequently, NSAIDs cannot be regarded as useful for treating fibromyalgia.

Some ecotoxicological studies have revealed their implication in different toxic effects and the only mechanism available nowadays to combat with this problem are the wastewater treatment plants, which in function of the system employed seem to be more successful in the pharmaceuticals degradation. The contrib...

Diazepam Is No Better Than Placebo When Added to Naproxen for Acute Low Back Pain
Conclusion Among ED patients with acute, nontraumatic, nonradicular low back pain, naproxen+diazepam did not improve functional outcomes or pain compared with naproxen+placebo 1 week and 3 months after ED discharge. (Source: Annals of Emergency Medicine)

Improved tolerance to transplanting injury and chilling stress in rice seedlings treated with orysastrobin
Publication date: Available online 7 February 2017 Source:Plant Physiology and Biochemistry Author(s): Naoto Takahashi, Yukari Sunohara, Masami Fujiwara, Hiroshi Matsumoto In addition to their fungicidal activity, strobilurin-type fungicides are reported to show enhancing effects on crop growth and yield. Previous studies suggested that the fungicide has a mitigating effect on abiotic stresses. However, there are few reports about growth enhancement through abiotic stress alleviation by strobilurin-type fungicides, but the mechanism of action of the growth enhancement is still not clear. The present study revealed that or...

Eudragit( ®) RL as a stabilizer for supersaturation and a substrate for nanocrystal formation.
Eudragit(®) RL as a stabilizer for supersaturation and a substrate for nanocrystal formation. Eur J Pharm Biopharm. 2017 Feb 08;: Authors: Dereymaker A, Cinghia G, Van den Mooter G Abstract In order to optimize supersaturation levels and avoid early drug precipitation, Eudragit(®) RL was tested as a carrier in solid dispersions, either alone or in combination with a hydrophilic polymer (PVP K25). In vitro dissolution performance of the spray dried solid dispersions was tested. The phase behavior of the produced solid dispersions was analyzed as well as dissolution precipitates. In case of weak...

Structure and physicochemical characterization of a naproxen – picolinamide cocrystal
Naproxen (NPX) is a nonsteroidal anti-inflammatory drug with pain- and fever-relieving properties, currently marketed in the sodium salt form to overcome solubility problems; however, alternative solutions for improving its solubility across all pH values are desirable. NPX is suitable for cocrystal formation, with hydrogen-bonding possibilities via the COOH group. The crystal structure is presented of a 1:1 cocrystal of NPX with picolinamide as a coformer [systematic name: (S)-2-(6-methoxynaphthalen-2-yl)propanoic acid – pyridine-2-carboxamide (1/1), C14H14O3 · C6H6N2O]. The pharmaceutically relevant physical...
