BACKGROUND The cyclo-oxygenase 2 inhibitor rofecoxib was recently withdrawn because of cardiovascular adverse effects. An increased risk of myocardial infarction had been observed in 2000 in the Vioxx Gastrointestinal Outcomes Research study (VIGOR), but was attributed to cardioprotection of naproxen rather than a cardiotoxic effect of rofecoxib. We used standard and cumulative random-effects m...

BACKGROUND AND OBJECTIVES Migraine is a highly prevalent neurological disorder with multiple peripheral and central mechanisms. Targeting a single mechanism for treating individual attacks as well as for performing the prophylaxis has been shown to be only partially effective. Recently, the role of combining agents for acute migraine treatment has gained attention and the combination of a tript...

Of one hundred patients originally entered for this trial eighty-three with acute musculo-skeletal disorders were treated with either naproxen sodium (SYNFLEX, Syntex), 550 mg initially followed by 275 mg four times daily, or piroxicam (FELDENE, Pfizer), 20 mg twice daily for two days then 20 mg once daily. Patients were assessed at admission, on day 4 and on day 8. Pain on passive movement, te...

BACKGROUND Lateral epicondylitis is a painful condition responsible for loss of function and sick leave for long periods of time. In many countries, the treatment guidelines recommend a wait-and-see policy, reflecting that no conclusions on the best treatment can be drawn from the available research, published studies and meta-analyses. METHODS/DESIGN Randomized double blind controlled clinic...

A capillary electrophoresis (CE) method was developed for the stereoselective determination of the non-steroidal anti-inflammatory drug (NSAID), S-naproxen, in tablets. Several beta-cyclodextrin derivatives (CDs) were tested as chiral selectors, including sulfobutyl-beta-CD (SBCD), carboxymethyl-beta-CD (CMCD), dimethyl-beta-CD (DMCD) and trimethyl-beta-CD (TMCD), in a phosphoric acid/triethano...

The release of reactive oxygen specie (ROS) by activated neutrophil is involved in both the antimicrobial and deleterious effects in chronic inflammation. The objective of the present investigation was to determine the effect of therapeutic plasma concentrations of non-steroidal anti-inflammatory drugs (NSAIDs) on the production of ROS by stimulated rat neutrophils. Diclofenac (3.6 microM), ind...

Red seaweeds synthesize a great variety of sulfated galactans. Sulfated polysaccharides (PLSs) from seaweed are comprised of substances with pharmaceutical and biomedical potential. The aim of the present study was to evaluate the protective effect of the PLS fraction extracted from the seaweed Gracilaria birdiae in rats with naproxen-induced gastrointestinal damage. Male Wistar rats were pretr...
