ReviewThe use of NSAIDs in rheumatic disorders 2005: a global perspective.
Population studies and World Health Organisation (WHO) statistics indicate that 10-50% of individuals suffer from musculoskeletal disorders. Up to 3% will be classified as disabled due to their bone and joint condition, and the majority will suffer from pain. Almost all will require non-steroidal anti-inflammatory drugs (NSAIDs) and other analgesics for their management. ⋯ Thus, the initial expected global benefits of the COX-2-selective inhibitors may be outweighed by their potential for toxicity. Recent studies have shown that the use of a proton-pump inhibitor drug with traditional NSAIDs and with COX-2-selective inhibitors has been shown to significantly reduce GI symptoms and peptic ulceration. Thus, the traditional NSAIDs have been re-established as the preferred choice in the management of arthritis and musculoskeletal disorders.

Comparative StudyDifferent effects of dexamethasone and the nitric oxide synthase inhibitor L-NAME on caerulein-induced rat acute pancreatitis, depending on the severity.
Effects of dexamethasone and N(G)-nitro-L-arginine methyl ester (L-NAME), the nitric oxide (NO) synthase inhibitor, on caerulein-induced acute pancreatitis were examined in rats. Acute pancreatitis was induced by caerulein (20 mug/kg, s.c.) given repeatedly 2 or 4 times every hour, and serum amylase levels, pancreas weight and myeloperoxidase (MPO) activity were measured 6 h after the first injection of caerulein. Dexamethasone (3 mg/kg) and L-NAME (30 mg/kg) were administered p.o. 30 min before the first injection of caerulein. ⋯ Both dexamethasone and L-NAME suppressed the severity of pancreatits, yet the effect of L-NAME as compared with dexamethasone was more potent against mild pancreatitis but less potent against severe pancreatitis. These results suggest that caerulein-induced acute pancreatitis shows different responsiveness to L-NAME and dexamethasone, depending on the severity; the former is more effective against pancreatitis with less inflammation, while the latter is more effective against pancreatitis with severe inflammation. It is assumed that endogenous NO may be involved in oedema formation as the early event in the development of acute pancreatitis.
