Cardiovascular Risk with Non-steroidal Anti-inflammatory Drugs: Clinical Implications
Abstract In February 2014, the US Food and Drug Administration (FDA) convened an advisory committee meeting to discuss the accumulated data relating to the cardiovascular risk of non-steroidal anti-inflammatory drugs (NSAIDs) and the potential implications on the class prescription labeling. The committee recommended, though not unanimously, that (1) the current data does not support the conclusion that naproxen has a lower risk of thrombotic events than other NSAIDs; (2) there is no latency period for the risk of cardiovascular thrombotic events; (3) there are some patient populations at increased risk for event...

Prophylaxis for acute gout flares after initiation of urate-lowering therapy
This review summarizes evidence relating to prophylaxis for gout flares after the initiation of urate-lowering therapy (ULT). We searched MEDLINE via PubMed for articles published in English from 1963 to 2013 using MEsH terms covering all aspects of prophylaxis for flares. Dispersion of monosodium urate crystals during the initial phase of deposit dissolution with ULT exposes the patient to an increased rate of acute flares that could contribute to poor treatment adherence. Slow titration of ULT might decrease the risk of flares. According to the most recent international recommendation, the two first-line options for prop...

Improvement of catalytic activity of lipase in the presence of calix[4]arene valeric acid or hydrazine derivative.
Abstract Sol-gel encapsulation is a simple but powerful method to enhance the enantioselectivity of lipase-catalyzed transformations in an isooctane/aqueous buffer solution. Candida rugosa lipase was encapsulated according to a sol-gel procedure in the presence and absence of calix[4]arene hydrazine or carboxylic acid derivatives with Fe3O4 magnetic nanoparticles as an additive. The activity of the encapsulated lipases was evaluated for the enantioselective hydrolysis of racemic Naproxen methyl ester and the hydrolysis of p-Nitrophenylpalmitate. The results indicate that the encapsulated lipase without calix[4]aren...

Migraine-Related Healthcare Resource Use and Costs for Subjects Prescribed Fixed-Dose Combination Sumatriptan/Naproxen Sodium vs. Single-Entity Oral Triptans in a Managed Care Population in the USA
Conclusion Study results suggest similar healthcare resource use patterns and associated costs when comparing S/NS and SOT across a triptan-naïve and triptan-experienced population. While the current study focuses on direct medical costs, future studies should extend beyond such a perspective to explore functional status, productivity, and health-related quality of life and satisfaction, attributes not captured in administrative claims data, but nonetheless important treatment goals.

Prevention and Treatment of NSAID Gastropathy
Opinion statement Nonsteroidal anti-inflammatory drug (NSAID) treatment will be necessary as part of our therapeutic armamentarium for many years to come. Therefore, safe prescription is mandatory in order to prevent adverse events. In the last two decades, new strategies and new drugs have been developed to reduce NSAID-associated upper gastrointestinal (GI) adverse events. Although the implementation of guidelines into clinical practice takes time, several studies have shown a recent and profound decrease in hospitalizations due to upper GI complications, which has been linked to widespread use of proton pump in...

Molecular interactions between some non-steroidal anti-inflammatory drugs (NSAID׳s) and bovine (BSA) or human (HSA) serum albumin estimated by means of isothermal titration calorimetry (ITC) and frontal analysis capillary electrophoresis (FA/CE).
Abstract The interactions between some non-steroidal anti-inflammatory drugs, NSAIDs, (naproxen, ibuprofen and flurbiprofen) and bovine (BSA) or human (HSA) serum albumin have been examined by means of two complementary techniques, isothermal titration calorimetry (ITC) and frontal analysis/capillary electrophoresis (FA/CE). It can be concluded that ITC is able to measure with high precision the strongest drug-albumin interactions but the higher order interactions can be better determined by means of FA/CE. Then, the combination of both techniques leads to a complete evaluation of the binding profiles between the s...

Cardiovascular Pharmacogenetics of Anti-Thrombotic Agents and Non-Steroidal Anti-Inflammatory Drugs.
Abstract The use of antithrombotic agents, particularly antiplatelet drugs like aspirin and clopidogrel, has been instrumental in decreasing the risk for adverse cardiovascular events across a wide range of patients. However, despite the established benefits, the use of these medications remains suboptimal. There is a high degree of inter-individual variation in response to these treatments, whereby patients experience occlusive thromboembolic events, in spite of maintaining an appropriate treatment regimen. This has lead to the notion of antithrombotic "resistance" or "poor responders", which has been a growing co...

A novel naproxen derivative capable of displaying anti-cancer and anti-migratory properties against human breast cancer cells
Conclusion: In this study we report that a naproxen-derivative (4) has powerful anti-inflammatory and anti-tumor properties as it induces appreciable amount of apoptosis in breast cancer cell line, and can also delay migration of cancer cells (MDA-MB-231) which would in turn delay cancer cell invasion and formation of secondary tumours in primary breast cancer patients. Thus, we propose that 4 is worthy of further investigation due to its potential as a therapeutic agent in anti-tumor treatment regimen. (Source: BMC Cancer)

Oral administration of whole dihomo-γ-linolenic acid-producing Saccharomyces cerevisiae suppresses cutaneous inflammatory responses induced by croton oil application in mice.
In this study, we investigated the efficacy of oral intake of heat-killed whole DGLA-producing yeast cells in the absence of lipid purification on cutaneous inflammation. Topical application of croton oil to mouse ears induces ear swelling in parallel with the increased production of chemokines and accumulation of infiltrating cells into the skin sites. These inflammatory reactions were significantly suppressed in a dose-dependent manner by oral intake of the DGLA-producing yeast cells for only 7 days. This suppression was not observed by the intake of the γ-linolenic acid-producing (C18:3n-6, an immediate precursor of D...

Druggists and pharmacists as gatekeepers: Sales routines and compliance with sales protocols for over-the-counter naproxen 275mg medicines in the Netherlands
Over the last decades, the sales of medicines has largely been shifted from prescription drugs to over-the-counter (OTC), non-prescription medicines. In 2008, for the first time ever, the growth in the sales OTC medicines exceeded the sales of prescription medicines [1]. Instead of going to the doctor for a specific medicine, more and more medicines are available without a prescription in a pharmacy or drugstore. On the one hand this eases the pressure on doctors and the health care system, but on the other hand people may abuse medicines more easily. (Source: Health Policy)

[Current state of knowledge and developments in the prophylaxis and acute treatment of migraine.]
Abstract For the acute treatment of the headache phase of a migraine attack, a variety of different pharmacotherapeutic treatment options exist. These range from nonspecifically acting non-opioid analgesics (e.g., paracetamol) and nonsteroidal anti-inflammatory substances (e.g., acetylsalicylic acid, ibuprofen, naproxen, diclofenac) to agents specifically interfering with the serotonin system (ergot alkaloids such as ergotamine and its derivatives, triptans). In patients with significant emesis co-occurring during an attack, additional antiemetics such as metoclopramide or domperidone may be administered. In migrai...

Cholestatic hepatic injury associated with vismodegib, aspirin, and naproxen use: a case study and review of vismodegib safety
ConclusionsHerein, we describe a potential serious adverse effect associated with vismodegib use. Whether the illness is directly attributable to the medication or the result of drug‐drug interactions between vismodegib and NSAIDs, practitioners should be aware of the possibility of hepatic injury in patients on vismodegib. Furthermore, patients need to be informed of the potential risks of vismodegib and should be monitored closely to ensure that life‐threatening complications of treatment are avoided.

Combination of tocolytic agents for inhibiting preterm labour.
CONCLUSIONS: It is unclear whether a combination of tocolytic drugs for preterm labour is more advantageous for women and/or newborns due to a lack of large, well-designed trials including the outcomes of interest. There are no trials of combination regimens using widely used tocolytic agents, such as calcium channel blockers (nifedipine) and/or oxytocin receptor antagonists (atosiban). Further trials are needed before specific conclusions on use of combination tocolytic therapy for preterm labour can be made.

The Effect of NSAID Prophylaxis and Operative Variables on Heterotopic Ossification After Hip Arthroscopy
Conclusion: Routine NSAID prophylaxis reduces but does not eliminate the incidence of HO in patients undergoing hip arthroscopy. Heterotopic ossification was more likely to develop in patients undergoing acetabuloplasty along with osteochondroplasty and in those who did not receive prophylactic postoperative NSAIDs. Side effects from the investigated NSAID regimen can be serious and should be weighed against the potential benefits in preventing the formation of HO.

Cigarette smoke induces alterations in the drug binding properties of human serum albumin.
Abstract Albumin is the most abundant plasma protein and serves as a transport and depot protein for numerous endogenous and exogenous compounds. Earlier we had shown that cigarette smoke induces carbonylation of human serum albumin (HSA) and alters its redox state. Here, the effect of whole-phase cigarette smoke on HSA ligand binding properties was evaluated by equilibrium dialysis and size-exclusion HPLC or tryptophan fluorescence. The binding of salicylic acid and naproxen to cigarette smoke-oxidized HSA resulted to be impaired, unlike that of curcumin and genistein, chosen as representative ligands. The binding...

Activation of mesocorticolimbic reward circuits for assessment of relief of ongoing pain: A potential biomarker of efficacy
Summary: Relief of ongoing pain may be reflected by increased dopamine efflux in the nucleus accumbens, providing a neurochemical efficacy measure for evaluation of novel analgesics.Abstract: Preclinical assessment of pain has increasingly explored operant methods that may allow behavioral assessment of ongoing pain. In animals with incisional injury, peripheral nerve block produces conditioned place preference (CPP) and activates the mesolimbic dopaminergic reward pathway. We hypothesized that activation of this circuit could serve as a neurochemical output measure of relief of ongoing pain. Medications commonly used clin...

A study of the energy absorption and exposure buildup factors of some anti-inflammatory drugs.
In this study, we investigated the radioprotective effects of some analgesic and anti-inflammatory compounds by evaluating buildup factors. The gamma ray energy absorption (EABF) and exposure buildup factors (EBF) were calculated to select compounds in a 0.015-15MeV energy region up to a penetration depth of 40mfp (mean free path). Variations of EABF and EBF with incident photon energy and penetration depth elements were also investigated. Significant variations in both EABF and EBF values were observed for several compounds at the moderate energy region. At energies below 0.15MeV, EABF and EBF values increased with decrea...

Use of a Physostigmine Continuous Infusion for the Treatment of Severe and Recurrent Antimuscarinic Toxicity in a Mixed Drug Overdose.
We present a case of physostigmine continuous infusion for the treatment of antimuscarinic symptoms in a polydrug overdose due to the ingestion of diphenhydramine along with bupropion, citalopram, acetaminophen, and naproxen. CASE PRESENTATION: A 13-year-old female presented with hyperthermia, myoclonus and rigidity, hallucinations, severe agitation, and antimuscarinic toxicity including inability to sweat after a polydrug overdose. Several doses of lorazepam were administered followed by physostigmine which produced resolution of hallucinations and attenuation of the antimuscarinic symptoms including perspiration, tem...

Sildenafil can induce the onset of a cluster headache bout.
We report the case of a man who experienced a cluster headache attack following each of 2 sildenafil doses. His symptoms were resolved by adding naproxen to his treatment regimen and changing his ED treatment from 50 mg of sildenafil to 5 mg of vardenafil. To our knowledge, no study has reported cluster headaches triggered by the less commonly used PDE-5 inhibitors, namely vardenafil and tadalafil. Urologists should be cautious in prescribing sildenafil to patients with ED and with a history of cluster headaches. In these patients, they should consider prescribing low-dose vardenafil or tadalafil instead. Failure to recogn...
