Sumatriptan plus naproxen for the treatment of acute migraine attacks in adults.
CONCLUSIONS: The conclusions of this review were not changed. Combination treatment was effective in the acute treatment of migraine headaches. The effect was greater than for the same dose of either sumatriptan or naproxen alone, but additional benefits over sumatriptan alone were not large. More participants achieved good relief when medication was taken early in the attack, when pain was still mild. Adverse events were more common with the combination and sumatriptan alone than with placebo or naproxen alone.

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...

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)

Fixed Drug Eruption Due to Selective Hypersensitivity to Naproxen with Tolerance to other Propionic Acid NSAIDs.
CONCLUSION: In our patient PT confirmed the diagnosis and allowed us to study the cross-reactivity between NSAIDs of the same group, and confirmed by SBOCT. Cross-reactivity between propionic acid derivatives was studied. This is a case of hypersensitivity to naproxen with good tolerance to other propionic acids NSAIDs (ibuprofen and ketoprofen) and nabumetone, confirmed by PT and SBOCT. Some relavent patents for fixed drug eruption are discussed. PMID: 27041368 [PubMed - as supplied by publisher] (Source: Recent Patents on Inflammation and Allergy Drug Discovery)

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.

Secondary malignant giant cell tumor of bone due to malignant transformation 40 years after surgery without radiation therapy, presenting as fever of unknown origin: a case report
Conclusions This is the first reported case, to the best of our knowledge, of the detection of a secondary malignant giant cell tumor of bone based on fever of unknown origin after long-term (40 years) follow-up. After curettage and bone grafting, giant cell tumor of bone may transform to malignancies within a few years or even decades after surgery. Therefore, meticulous follow-up is essential. The fever might be attributable to the tumor releasing inflammatory cytokines. Not only pain and swelling but also continuous pyrexia may suggest the diagnosis of a secondary malignant giant cell tumor of bone. (Source: ...

Gastrointestinal safety, chemotherapeutic potential, and classic pharmacological profile of NOSH‐naproxen (AVT‐219) a dual NO‐ and H2S‐releasing hybrid
Abstract Naproxen (NAP) is a potent nonsteroidal anti‐inflammatory drug (NSAID) with a favorable cardiovascular profile. However, its long‐term use may lead to serious gastrointestinal and renal side effects. NOSH‐ (nitric oxide and hydrogen sulfide) releasing naproxen (NOSH‐NAP, AVT‐219) belongs to a new class of anti‐inflammatory agents designed to overcome these limitations. We compared the gastrointestinal safety, anti‐inflammatory, analgesic, antipyretic, and antiplatelet properties of AVT‐219 to that of NAP in preclinical animal models. We also evaluated its anticancer effects in 11 human cancer cell ...

Effect of NSAIDs on the aminopeptidase activity of cultured human osteoblasts
The objective was to determine the effect of certain NSAIDs on the AP activity of osteoblasts. Primary cultures of osteoblast were treated with different concentrations of indomethacin, meloxicam, naproxen, nimesulide, and piroxicam. The AP activity was fluorimetrically determined using aminoacyl-β-naphthylamides (aa-βNAs) as substrates: Ala-βNA, Arg-βNA, Gly-βNA, Leu-βNA, Lys-βNA, Met-βNA, and Phe-βNA. The five NSAIDs showed an inhibitory effect of AP activity against the study substrates depending on the dose tested. Meloxicam and piroxicam had the highest inhibitory effect on enzymatic activity, with an IC50 of...

1: comparative effect of selective and non-selective cox-2 inhibitors on lipid accumulation in human macrophages
Conclusions Here we report that only specific COX-2 inhibitors might contribute to atherogenesis by promoting lipid overload and lipoprotein accumulation. This may explain, in part, the increased CV risk in patients taking COX-2 inhibitors for extended periods. Despite increased scavenger receptor expression, naproxen and acetaminophen do not impact lipid content, perhaps because efflux pathways remain intact. (Source: Journal of Investigative Medicine)

Indomethacin inhibits tetrodotoxin-resistant Na(+) channels at acidic pH in rat nociceptive neurons.
Abstract Non-steroidal anti-inflammatory drugs (NSAIDs) are well-known inhibitors of cyclooxygenases (COXs) and are widely used for the treatment of inflammatory pain; however several NSAIDs display COX-independent analgesic action including the inhibition of voltage-gated Na(+) channels expressed in primary afferent neurons. In the present study, we examined whether NSAIDs modulate tetrodotoxin-resistant (TTX-R) Na(+) channels and if this modulation depends on the extracellular pH. The TTX-R Na(+) currents were recorded from small-sized trigeminal ganglion neurons by using a whole-cell patch clamp technique. Among...

Automated evaluation of protein binding affinity of anti-inflammatory choline based ionic liquids.
Abstract In this work, an automated system for the study of the interaction of drugs with human serum albumin (HSA) was developed. The methodology was based on the quenching of the intrinsic fluorescence of HSA by binding of the drug to one of its binding sites. The fluorescence quenching assay was implemented in a sequential injection analysis (SIA) system and the optimized assay was applied to ionic liquids based on the association of non-steroidal anti-inflammatory drugs with choline (IL-API). In each cycle, 100µL of HSA and 100µL of IL-API (variable concentration) were aspirated at a flow rate of 1mLmin(-1) a...

Synthesis of Amino-ADT Provides Access to Hydrolytically Stable Amide-Coupled Hydrogen Sulfide Releasing Drug Targets
SynlettDOI: 10.1055/s-0035-1560603As additional physiological functions of hydrogen sulfide (H2S) are discovered, developing practical methods for exogenous H2S delivery is important. In particular, nonsteroidal anti-inflammatory drugs (NSAIDs) functionalized with H2S-releasing anethole dithiolethione (ADT-OH) through ester bonds are being investigated for their combined anti-inflammatory and antioxidant potential. The chemical robustness of the connection between drug and H2S-delivery components, however, is a key and controllable linkage in these compounds. Because esters are susceptible to hydrolysis, particularly under...

A working model for the assessment of disruptions in social behavior among aged rats: The role of sex differences, social recognition, and sensorimotor processes.
In this study, both males and females exhibited late aging-related reductions in social interactions, but these changes were more pronounced in females. Additionally, sensorimotor performance was shown to be impaired in 24-month-olds, but not 18-month-olds, with this deficit more evident in males. Finally, Exp. 3 examined whether aging-related inflammation could account for declines in social behavior during late aging by administering naproxen (0, 7, 14, and 28mg/kg; s.c.)-a non-steroidal anti-inflammatory drug-to 18-month-old females. Results from this study revealed that social behavior was unaffected by acute or repeat...

The Influence of Efflux Pump Inhibitors on the Activity of Non-Antibiotic NSAIDS against Gram-Negative Rods
Conclusions The effects of PAβN on the susceptibility of bacteria to NSAIDs indicate that some NSAIDs are substrates for efflux pumps in Gram-negative rods. Morever, Aspirin probably induced efflux-mediated resistance to fluoroquinolones in a few E. coli strains. (Source: PLoS One)

Protective Effect of 4-(3, 4-Dihydroxyphenyl)-3-buten-2-one from Phellinus linteus on Naproxen-induced Gastric Antral Ulcers in Rats.
Abstract The present study was investigated the protective effect of naturally purified 4-(3, 4-dihydroxyphenyl)-3-buten-2-one (DHP) from Phellinus linteus against naproxen-induced gastric antral ulcers in rats. To verify the protective effect of DHP on naproxen-induced gastric antral ulcers, various doses (1, 5, and 10 µg/kg) of DHP were pretreated for 3 days, and then gastric damage was caused by 80 mg/kg naproxen applied for 3 days. DHP prevented naproxen-induced gastric antral ulcers in a dose-dependent manner. Especially, 10 µg/kg DHP showed the best protective effect against naproxen-induced gastric antral ...
