Tenidap, ibuprofen, and naproxen, at therapeutically attainable concentrations, significantly inhibited the proliferative response of T cells to IL-2. In contrast, indomethacin, piroxicam, and sulindac did not alter this response. Tenidap had a direct inhibitory effect on the response of activated T cells to IL-2. Both ibuprofen and naproxen interfered with the binding of IL-2 to T cells.

The main aim of this study was to confirm in an Italian population affected by tension-type headache (TTH) the good profile of safety and tolerability of the combination paracetamol 1,000 mg-caffeine 130 mg (PCF) observed in previous studies, by a comparison with naproxen sodium 550 mg (NAP) and placebo (PLA). A secondary objective was to assess the efficacy of PCF in the acute treatment of TTH. This was a multicentre, randomised, double-blind, double-dummy, crossover, placebo-controlled trial. Tolerability was assessed by recording adverse events by the patient in the 4-h post-dose treatment. To assess the efficacy, the sum of pain intensity differences (SPID) and the total pain relief (TOTPAR) were calculated. Comparing PCF and NAP and PCF and PLA for tolerability, the difference was nonsignificant but the result regarding noninferiority was inconclusive, whilst NAP was noninferior to PLA. As regards SPID and TOTPAR, both PCF and NAP were better than placebo (P < 0.05), but not significantly different from each other. In conclusion, PCF was well-tolerated and effective in the treatment of acute TTH.
NSAIDs reduce HMB when compared with placebo but are less effective than either tranexamic acid or danazol. However, adverse events are more severe with danazol therapy. In the limited number of small studies suitable for evaluation, no significant difference in efficacy was demonstrated between NSAIDs and other medical treatments such as oral luteal progestogen, ethamsylate, OCC or IUS.

The respiratory route is an important portal for human exposure to a large variety of substances. Consequently, there is an urgent need for realistic in vitro strategies for evaluation of the absorption of airborne substances with regard to safety and efficacy assessment. The present study investigated feasibility of a 3D human airway epithelial model to study respiratory absorption, in particular to differentiate between low and high absorption of substances. Bronchial epithelial models (MucilAir™), cultured at the air-liquid interface, were exposed to eight radiolabeled model substances via the apical epithelial surface. Absorption was evaluated by measuring radioactivity in the apical compartment, the epithelial cells and the basolateral culture medium. Antipyrine, caffeine, naproxen and propranolol were highly transported across the epithelial cell layer (>5%), whereas atenolol, mannitol, PEG-400 and insulin were limitedly transported (<5%). Results indicate that the 3D human airway epithelial model used in this study is able to differentiate between substances with low and high absorption. The intra-experimental reproducibility of the results was considered adequate based on an average coefficient of variation (CV) of 15%. The inter-experimental reproducibility of highly absorbed compounds was in a similar range (CV of 15%), but this value was considerably higher for those compounds that were limitedly absorbed. No statistical significant differences between different donors and experiments were observed. The present study provides a simple method transposable in any lab, which can be used to rank the absorption of chemicals and pharmaceuticals, and is ready for further validation with respect to reproducibility and capacity of the method to predict respiratory transport in humans.
One hundred twenty patients with moderate to severe menstrual cramping were randomized. Eighty-seven patients completed all treatment cycles.

The influence of systemic antifibrinolytic and antiprostaglandin medication on post-operative central corneal thickness was studied. Thirty patients underwent uncomplicated intracapsular cataract extraction with implantation of anterior chamber lens. The patients received either tranexamic acid, naproxen or both. The post-operative oedema did not differ significantly between the three groups studied. Models for studying changes in central corneal thickness are discussed. A review of the influence of drugs on corneal thickness is presented.
In comparison with the biocatalyst engineering and medium engineering approaches, very few examples have been reported on using the substrate engineering approach such as substrate-assisted catalysis (SAC) for naturally occurring or engineered lipases and serine proteases to improve the enzyme activity and enantioselectivity. By employing lipase-catalyzed hydrolysis of (R,S)-naproxen esters in water-saturated isooctane as the model system, we demonstrate the proton shuttle device to the leaving alcohol of the substrate as a new means of SAC to effectively improve the lipase activity or enantioselectivity. The result cannot only provide a strong evidence for the rate-limiting proton transfer for the bond-breaking of tetrahedron intermediate of the acylation step, but also sheds light for performing the hydrolysis, transesterification or aminolysis in organic solvents for the ester substrate that originally lipases cannot catalyze, but now can after introducing the device.

The new potentiometric method was shown to be reliable for determining the solubility-pH profiles of uncharged ionizable drug substances. Its speed compared to conventional equilibrium measurements, its sound theoretical basis, its ability to generate the full solubility-pH profile from a single titration, and its dynamic range (currently estimated to be seven orders of magnitude) make the new pH-metric method an attractive addition to traditional approaches used by preformulation and development scientists. It may be useful even to discovery scientists in critical decision situations (such as calibrating computational prediction methods).

Patients with knee osteoarthritis improved more with naproxen treatment than patients with hip osteoarthritis, as monitored by WOMAC and the SF-36 domains bodily pain and role-physical. These findings warrant further investigation and strongly suggest that efficacy of treatment of osteoarthritis of knee and hip should be evaluated separately.

On the basis of the current review, there is scant evidence to guide clinicians about how gastrointestinal or liver comorbidities should influence the choice of pain treatment in patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis or other spondylarthritis. Based upon additional studies that included a mixed population of participants with a range of rheumatic conditions, NSAIDs should be used cautiously in patients with inflammatory arthritis and a history of gastrointestinaI comorbidity as there is consistent evidence that they may be at increased risk.

Twelve cases of drug-induced pneumonitis were clinically investigated. Treatment of antimicrobial agents in 8 cases of drug-induced pneumonitis ranged from 7-21 days (mean 12 days) and that of other drugs in 4 cases from 18-150 days (mean 70 days). The patients developed fever and dyspnea at a high rate of frequency. Abnormal laboratory findings included increased IgE (44%), eosinophilia (36%), and increased GOT and GPT in 33%. Chest X-ray films revealed a large reticulo-nodular or ground glass shadows in both lung fields. The results of lymphocyte stimulation tests were positive in 5 of 11 cases (45%). Eight cases demonstrated a rapid improvement by discontinuation of the drug and corticosteroid was administered in 4 cases. The drug received by the patient and their known risk of pulmonary toxicity should be kept in mind in order to reach a diagnosis of drug-induced pneumonitis and grasp the clinical picture of this disease. A provocation test is potentially dangerous, therefore it should not be carried out lightly.

A double-blind clinical trial was carried out on 2 parallel groups each of 20 in-and out-patients with classical or definite rheumatoid arthritis, to compare the efficacy and tolerance of proglumetacin, a new non-steroidal anti-inflammatory drug, with naproxen. Each patient received daily either 300 mg proglumetacin or 500 mg naproxen in two divided doses, at meals, over a period of 3 months. The whilst both drugs were effective in the long-term treatment of chronic rheumatoid arthritis, proglumetacin appeared to be somewhat more effective than naproxen in reducing the duration of morning stiffness, the articular inflammation score index, erythrocyte sedimentation rate and the dosage of concomitant basic medication. Few side-effects were reported but 1 of the 2 patients in the naproxen group who developed allergic reactions had to be withdrawn during the first few days of treatment.
We conducted a case control study of colon cancer designed to compare effects of selective and non-selective COX-2 inhibitors. A total of 326 incident colon cancer patients were ascertained from the James Cancer Hospital, Columbus, Ohio, during 2003-2004 and compared with 652 controls with no history of cancer and matched to the cases at a 2:1 ratio on age, race, and county of residence. Data on the past and current use of prescription and over the counter medications and colon cancer risk factors were ascertained using a standardized risk factor questionnaire. Effects of COX-2 inhibiting agents were quantified by calculating odds ratios (OR) and 95% confidence intervals.

The nonsteroidal anti-inflammatory drugs (NSAIDs) have been repeatedly associated with photosensitivity reactions. The underlying mechanism however is not known, and the clinical features are not always consistent with either a phototoxic or a photoallergic mechanism. In this study, four NSAIDs were investigated for their phototoxicity potential in human volunteers using an oral dosing protocol. Phototoxicity, consisting of wheal-and-flare reactions following exposure to ultraviolet radiation, was demonstrated following the administration of naproxen and nabumetone, but was not seen in volunteers who received piroxicam, a drug reported to cause photosensitivity. Thus, although certain NSAIDs are potentially capable of producing phototoxicity reactions, others can presumably provoke clinical photosensitivity through other mechanisms.

A murine delayed-type hypersensitivity (DTH) model was developed as a tool for drug discovery. Time course studies indicated that hind paw swelling was maximal at four days post-sensitization with picryl chloride. A pharmacological survey involving daily administration of drugs revealed that as a class, the glucocorticoids (e.g. dexamethasone and corticosterone) were the most potent inhibitors of the DTH response. The immunosuppressants, methotrexate, cyclosporine A, cyclophosphamide, and azathioprine, were all able to suppress the DTH response, with methotrexate being the most potent suppressor of paw swelling. Likewise, non-steroidal anti-inflammatory agents (e.g. indomethacin, piroxicam, diclofenac, and naproxen) all suppressed the DTH response, with indomethacin and piroxicam being the most potent suppressors. A series of central nervous system affecting drugs, including serotonin agonists [e.g. trifluromethylphenylpiperazine (tfMPP), 1-(3-chlorophenyl)piperazine (mCPP), quipazine, and 8-hydroxy-DPAT hydrobromide (8-OH DPAT)], and serotonin antagonists (e.g. cyproheptadiene, ketanserin, and mianserin) were examined in the 4 day DTH model. Except for 8-OH DPAT, all of the serotonin agonists were able to suppress the DTH response, with mCPP being the most potent suppressor. In contrast, none of the tested serotonin antagonists had any effect on the DTH response. The histamine antagonists (e.g. cimetidine and chlorphineramine) were largely ineffective in suppressing the DTH response. These data provide a pharmacological profile for a series of immunomodulator, non-steroidal anti-inflammatory, and central nervous system active compounds in a classic immunologic model.

After the eccentric exercise, plasma CK levels were similarly elevated in both naproxen and placebo conditions (F=1.42; p=0.25). After DOMS developed, naproxen reduced the perception of soreness on day 3, when muscle soreness was highest (F=2.20; p=0.04). After treatments with naproxen, peak quadriceps torque during leg extension at 60 degrees/s was higher than that after treatment with the placebo (F=4.77; p=0.04). There were no significant differences between the naproxen and placebo conditions for leg extension at 180 degrees/s (F= 1.66; p=0.21) and 300 degrees/s (F=0.71; p=0.41).

Forty to 78% of the patients using sumatriptan for the acute treatment of migraine may present recurrence at least occasionally. The concomitant use of a NSAID (nonsteroidal anti-inflammatory drug) has been recommended to decrease the recurrence rate. Sixty seven patients that treated successfully 8 migraine attacks with 100 mg of sumatritpan PO and presented recurrence in at least 5 attacks were studied prospectively. The patients received 100 mg of sumatriptan and 550 mg of naproxen sodium PO to treat 4 consecutive moderate or severe migraine attacks. The recurrence rate, once at least 62.5% (5 out of 8 attacks), decreased to 14.2% (38 out of 268 attacks) with the combination of compounds (p<0.0001). We then studied two groups of 13 patients made randomicaly from the 67 initially evaluated, that were given sumatriptan 100 mg plus naproxen sodium 550 mg or placebo, in a double-blind design, to treat 3 other consecutive migraine attacks. Each group of patients treated 39 attacks. The recurrence among the patients taking sumatriptan plus placebo was 59% (23 out of 39 attacks) and the recurrence presented by the group taking sumatriptan plus naproxen was 25.5% (10 out of 39 attacks) (p<0.0003). We concluded that the combination of sumatriptan plus naproxen sodium decreases significantly migraine recurrence presented by patients taking sumatriptan alone.

A 22-year-old Japanese man developed polyarthritis with fever and urethritis. He was diagnosed as Reiter's syndrome since he was found to have uveitis and persistent aseptic pyuria. Although, he was negative for HLA-B27 or any other HLA-B27 cross-reactive MHC class I antigens, he was positive for HLA-B51. The laboratory examination showed significant elevation of serum IgG and IgA anti-Chlamydia antibodies. He was successfully treated with a combination of doxycycline, naproxen, salazosulfapyridine and methotrexate with a decrease in IgG and IgA anti-Chlamydia antibodies. Previous studies provided evidence that HLA-B51 itself might be involved in the development of Behcet's disease, which shares common features with Reiter's syndrome, such as uveitis, skin lesions, and polyarthritis. It is therefore suggested that combination of Chlamydia infection and HLA-B51 might play a role in the pathogenesis of Reiter's syndrome in our patient.
