An isocratic supercritical/subcritical fluid chromatography method for the separation of naproxen enantiomers on the Kromasil CHI-TBB column was investigated. The mobile phase was composed of supercritical CO2 with 2-propanol as modifier. The experimental conditions were temperature 293 K-323 K, pressure 9.4 MPa-21.3 MPa, and 2-propanol concentration 6%-15% (by mass), respectively. The enthalpic contribution to the overall enantiomer transfer energy was more important than the entropic contribution in the temperature range examined. The preferred operation conditions were 293 K, 9.4 MPa, and the concentration of 2-propanol in the mobile phase 11% (by mass).

This research advances the knowledge of ion-exchange of four non-steroidal anti-inflammatory drugs (NSAIDs) - diclofenac (DCF), ibuprofen (IBP), ketoprofen (KTP), and naproxen (NPX) - and one analgesic drug-paracetamol (PCM) - by strong-base anion exchange resin (AER) in synthetic ureolyzed urine. Freundlich, Langmuir, Dubinin-Astakhov, and Dubinin-Radushkevich isotherm models were fit to experimental equilibrium data using nonlinear least squares method. Favorable ion-exchange was observed for DCF, KTP, and NPX, whereas unfavorable ion-exchange was observed for IBP and PCM. The ion-exchange selectivity of the AER was enhanced by van der Waals interactions between the pharmaceutical and AER as well as the hydrophobicity of the pharmaceutical. For instance, the high selectivity of the AER for DCF was due to the combination of Coulombic interactions between quaternary ammonium functional group of resin and carboxylate functional group of DCF, van der Waals interactions between polystyrene resin matrix and benzene rings of DCF, and possibly hydrogen bonding between dimethylethanol amine functional group side chain and carboxylate and amine functional groups of DCF. Based on analysis of covariance, the presence of multiple pharmaceuticals did not have a significant effect on ion-exchange removal when the NSAIDs were combined in solution. The AER reached saturation of the pharmaceuticals in a continuous-flow column at varying bed volumes following a decreasing order of DCF > NPX ≈ KTP > IBP. Complete regeneration of the column was achieved using a 5% (m/m) NaCl, equal-volume water-methanol solution. Results from multiple treatment and regeneration cycles provide insight into the practical application of pharmaceutical ion-exchange in ureolyzed urine using AER.

In a two-period, double-blind, crossover study, patients with osteoarthritis of the knee and/or hip received etodolac 300 mg twice daily for 4 weeks and naproxen 500 mg twice daily for 4 weeks in random order. The assessment of efficacy showed that naproxen and etodolac were equally effective in the management of pain and stiffness in osteoarthritis. However, a significantly higher proportion of patients preferred naproxen to etodolac for the relief of pain intensity. The incidence of adverse events caused by either drug was the same.
Using protocol 1 naproxen, Iressa, resveratrol, and low and high dose aspirin altered the formation of large bladder tumors by 87% (decreased), 90% (decreased), 3% (increased), 6% (decreased) and 60% (decreased), respectively. Using protocol 2 Iressa and naproxen were also highly effective. Protocol 3 evaluation revealed that only Iressa caused a significant decrease in microscopic bladder cancers (63%).
A 53-year-old Caucasian woman with long-standing, well controlled, severe rheumatoid arthritis, treated with methotrexate, salazopyrin, naprosyn, prednisone and plaquenil, presented with progressive visual loss in each eye. She had a past history of non-necrotizing anterior scleritis that was treated with increased doses of prednisone. She developed left then right central scotomas, reduced vision and optic atrophy. Eventually a diagnosis of methotrexate-induced optic atrophy was made.

A double-blind crossover trial compared Butacote, 200 mg b.d. with naproxen, 250 mg b.d., each given for four weeks, in the treatment of rheumatoid arthritis. The trial was multicentre, and twenty-six general practitioners admitted forty-eight patients. Seven patients dropped out: two for technical reasons; one in each treatment group because of exacerbation of symptoms; one because of intolerance of rescue analgesic; and two with gastric intolerance to naproxen. Both drugs were effective in relieving pain, morning stiffness, and joint tenderness, as compared with the condition before the trial. There was little effect on grip strength or joint size, and no real differences between the two drugs. The two preparations had a similar frequency and spectrum of side-effects, except that oedema did not occur with naproxen, and rash did not occur with Butacote. Gastro-intestinal upsets were the commonest unwanted effect but only two patients had to stop treatment for this reason, both while taking naproxen. Although the doctors preferred each drug on an equal number of occasions, the patients preferred Butacote to naproxen almost twice as often (20:11), particularly when Butacote was given after naproxen. The reason for this divergence of opinions is not obvious.

The aim of this study was to evaluate the joint count for erosions in patients with erosive osteoarthritis (EOA) of the hands treated with 800 mg/day of orally administered chondroitin sulfate plus naproxen, compared with that of patients administered naproxen only. Twenty-four consecutive patients (22 women and two men, mean age 53.0 +/- 6) suffering from symptomatic OA and with radiographic characteristics of EOA were studied. The patients were divided into two groups of 12 patients each. The first group took naproxen 500 mg/day only. The second group was treated with chondroitin sulfate 800 mg/day orally plus naproxen 500 mg/day. Radiological hand examinations were performed at baseline and again after 12 and 24 months. In both groups, the joint count for erosions showed a general tendency to increase over time. Progression of erosions at 24 months was lower in patients treated with 800 mg/day chondroitin sulfate plus naproxen than in patients taking naproxen only (p <0.05). Chondroitin sulfate failed to stop the usual time-associated progression in the number of finger joints presenting erosions in EOA of the hands. It was, however, associated with a lower increase in the number of finger joints with erosions detected after 2 years of radiological observation.

This project compared the effect of formulation variables on the dissolution performance of model Biopharmaceutics Classification System (BCS) Class II drugs from hard gelatin capsules using statistical analysis and Bayesian networks. The drugs chosen for this study were carbamazepine (CAR), chlorpropamide (CHL), diazepam (DIA), ketoprofen (KET), and naproxen (NAP). Formulations contained anhydrous lactose, microcrystalline cellulose, sodium stearyl fumerate, sodium lauryl sulfate, and croscarmellose sodium. A Box-Behnken experimental design was used in the statistical analysis. The weakly acidic drugs were tested using USP apparatus II with capsule sinkers in 0.1M pH 6.8 Potassium Phosphate buffer. The weakly basic drugs were tested using USP apparatus I in 0.1N HCl buffer. Mean dissolution profiles were compared via calculation of the similarity factor. The Box-Behnken experimental design was found to be useful in assessing primary and secondary excipient effects on dissolution. The Bayesian Network developed for the dataset mirrored the key excipient effects on dissolution performance.

The purpose of this study was to investigate the influence of different types of chitosan and of the preparation technique of the drug-polymer combination in improving the dissolution and permeation abilities of naproxen, a very poorly water-soluble anti-inflammatory drug. Drug-chitosan systems were prepared by simple physical mixing, kneading, cogrinding, or coevaporation using five types of chitosan (base and glutamate or hydrochloride salts, both at two different molecular weights). The products were tested for drug-dissolution behavior and for permeation properties through both Caco-2 cell monolayers and artificial lipophilic membranes. All combinations with chitosan base were significantly (p < .01) more effective in enhancing drug-dissolution rate than those with both its salts, probably in virtue of its higher amorphizing effect toward the drug, as observed in solid-state studies. A different rank order was found in permeation experiments in which chitosan glutamate was the most powerful partner in improving the drug-apparent permeability (p < .01), followed by the hydrochloride salt (p < .05), whereas no significant effect was obtained with chitosan base. Cogrinding was the most powerful technique in promoting both dissolution and permeation properties of the drug, thus pointing out the importance of the preparation method in obtaining efficacious drug-carrier systems. Finally, the good correspondence between permeation experiments with Caco-2 cells and those with the artificial lipophilic membrane indicated the suitability of this latter in preformulation studies for a rapid screening of the best carrier and the most efficient drug-carrier preparation method for improving the biopharmaceutical properties of drugs.

A novel derivative beta-cyclodextrin (beta-CD) bonded silica gel (beta-CD/SiO2) was prepared via carbodiimide activation and used as a chiral stationary phase (CSP). The beta-CD/SiO2 CSP was characterized by X-ray photoelectron spectroscopy and FTIR spectroscopy to prove the successful immobilization of beta-CD onto the surface of the silica gel. The thermal behavior of the CSP was studied by differential scanning calorimetry and then used for the chiral separation of racemic naproxen using HPLC. Several factors affecting the separation efficiency of naproxen enantiomers were investigated systematically. The following parameters were selected: methanol-0.01 M phosphate buffer solution (85 + 15, v/v, pH 3.5) was the mobile phase, the flow rate was 1.0 mL/min, and the column temperature was 35 degrees C. Under optimal conditions, the racemic naproxen was efficiently separated with a resolution factor (R(S)) of 1.70 and a separation factor (alpha) of 1.25. This method was successfully used for the enantiomeric separation and purity assessment of naproxen in commercial naproxen sustained release tablets.

This study examined the evolution of absorbance spectra of wastewater ozonated using varying initial ozone concentrations or treatment times; concomitant changes of concentrations of trace-level pharmaceuticals were also quantified. The absorbance of ozonated wastewater decreased due to the degradation of chromophores in effluent organic matter (EfOM). The relative decrease of absorbance (DeltaA/A(0)) ranged from < 30% for lambda < 250 nm to > 80% for lambda > 320 nm. The removal of atenolol, carbamazepine, DEET, diclofenac, gemfibrozil, ibuprofen, iopromide, naproxen, propranolol, sulfamethoxazole, trimethoprim, and p-chlorobenzoic acid was strongly correlated with DeltaA/A(0) values. The observed features were hypothesized to correspond to the engagement of kinetically distinct groups of EfOM chromophores. Modeling of the evolution of EfOM absorbance and concurrent degradation of trace-level organic species based on this hypothesis confirmed its applicability and utility for practical applications and theoretical exploration.

We found that the combination of sumatriptan/naproxen was effective in blocking capsaicin stimulation of pro-inflammatory proteins implicated in the development of peripheral and central sensitization in response to capsaicin activation of trigeminal neurons. Based on our findings that sumatriptan and naproxen regulate expression of different proteins in trigeminal ganglia and the spinal trigeminal nucleus, we propose that these drugs function on therapeutically distinct cellular targets to suppress inflammation and pain associated with migraine.

Fifty patients presenting to hospital with acute gastrointestinal bleeding while taking piroxicam, indomethacin, diclofenac or naproxen and age, sex, musculoskeletal disease and drug matched community dwelling controls, up to two for each index case, who had not bled were recruited. Clinical details including duration of therapy were recorded. Bleeders discontinued the implicated NSAID at presentation, controls at least five half-lives before the study. Bleeders were contacted by letter 1 month after discharge and invited to take part and were studied after a median delay of 5 months. Subjects received an oral dose of their respective NSAID and venous blood was sampled, over a period determined by the half-life of the NSAID. Plasma concentrations were determined by high performance liquid chromatography.

Tiaprofenic acid is a new non-steroidal anti-inflammatory agent advocated for use in rheumatoid arthritis, osteoarthritis, musculoskeletal disorders, soft-tissue injuries and inflammatory conditions and acute pain of varying origin. Published data suggest that tiaprofenic acid 600 mg daily in 2 or 3 divided doses is comparable in effectiveness with aspirin, diclofenac, ibuprofen, indomethacin, naproxen, piroxicam and sulindac in the treatment of rheumatoid arthritis and osteoarthritis. More controlled clinical trials are necessary to evaluate its potential in rheumatic conditions other than rheumatoid arthritis and osteoarthritis. In controlled studies in patients with acute pain following surgery or trauma, tiaprofenic acid was more effective than placebo and as effective as aspirin and indomethacin. While tiaprofenic acid produced fewer side effects than aspirin in rheumatoid arthritis treatment, and indomethacin in the treatment of osteoarthritis, results have generally shown the short term tolerability of tiaprofenic acid to be similar to that of other non-steroidal anti-inflammatory drugs. As no one of the non-steroidal anti-inflammatory agents is the most suitable drug for all patients requiring such therapy, tiaprofenic acid should be considered along with other drugs of this type in the therapy of arthritic conditions and of acute postoperative or posttraumatic pain.

In a double-blind study of 18 patients with coxarthrosis the effect of 3 naproxen doses (0.5, 1.0, and 1.5 g daily) and 2 naproxen doses combined with paracetamol (0.5 g + 4 g daily and 1.0 g + 4 g daily) was investigated. Plasma levels of naproxen and paracetamol were measured (HPLC), and clinical assessment of pain, joint movement, activity of daily life and side-effects were performed at the end of the 5 treatment periods. A relationship was found between the 3 naproxen doses, naproxen plasma levels, pain at rest, and pain during movement. The combined treatment was more effective than treatment with the same naproxen dose alone. The effect of naproxen (0.5 g daily) combined with paracetamol (4 g daily) did not differ from that obtained during treatment with higher naproxen doses only. Furthermore, the effect of the highest naproxen dose was not better than the effect of the lower naproxen dose (1.0 g daily) combined with paracetamol. The main finding was that treatment with naproxen and paracetamol is more effective than treatment with higher naproxen doses alone.
