Severe ocular side effects with acetazolamide: case report.
CONCLUSION: This was an iatrogenic case of acute angle closure induced by an anterior displacement of the irido-lenticular complex, secondary to the use of acetazolamide. The treatment of this condition involves suspending the drug responsible and applying topical corticosteroids, hypotensive and cycloplegic eye drops, with the aim of lowering the eye pressure and the degree of myopia due to the re-positioning of the irido-lenticular complex.

Method for quantifying NSAIDs and clofibric acid in aqueous samples, lumpfish (Cyclopterus lumpus) roe, and zebrafish (Danio rerio) eleutheroembryos and evaluation of their bioconcentration in zebrafish eleutheroembryos.
Abstract Pharmaceuticals such as nonsteroidal anti-inflammatory drugs (NSAIDs) and lipid regulators are being repeatedly detected at low concentrations (pg · mL(-1)-ng · mL(-1)) in the environment. A large fraction of these compounds are ionizable. Ionized compounds show different physico-chemical properties and environmental behavior in comparison to their neutral analogs; as a consequence, the quantification methods currently available, based on the neutral molecules, might not be suitable to detect the corresponding ionized compounds. To overcome this problem, we developed a specific analytical method ...

Introduction of high nitrogen doped graphene as a new cationic carrier in electromembrane extraction
This paper proposes for the first time, the use of high nitrogen doped graphene (HND‐G) as a new cationic carrier for the enhancement of electromembrane extraction (EME) performance. Sensitivity of EME was improved by the modification of supported liquid membrane composition through the addition of HND‐G into 1‐octanol for the extraction of naproxen and sodium diclofenac as model acidic drugs. The comparison between HND‐G‐modified EME and conventional EME showed that HND‐G could increase the overall partition coefficient of acidic drugs in the membrane due to the fact that HND‐G acts as an ion pair reagent an...

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.

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)

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: ...

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 Pharmacology of Indomethacin.
CONCLUSIONS: NSAIDs easily enter the brain, but their high protein binding limits absolute amount of entry. All work similarly as either nonselective or selective cyclooxygenase inhibitors, but indomethacin may have more potent vasoconstrictive activity and unique direct neuronal or nitric oxide-dependent inhibitory pathway activity.

Sorption of diclofenac and naproxen onto MWCNT in model wastewater treated by H2O2 and/or UV.
Abstract The application of oxidation processes such as UV and/or H2O2 will change the physicochemical properties of carbon nanotubes (CNT). It may affect the sorption affinity of CNT to different contaminants and then affect their fate in the environment. In the present study the adsorption of two very common used pharmaceuticals (diclofenac and naproxen) onto CNT treated by UV, H2O2 or UV/H2O2 was investigated. Four different adsorption models (Freundlich, Langmuir, Temkin, Dubinin-Radushkevich) were tested. The best fitting of experimental data was observed for Freundlich or Langmuir model. The significant relat...

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...
