Comparative Study"Selective" switching from non-selective to selective non-steroidal anti-inflammatory drugs.
Non-steroidal anti inflammatory drugs (NSAIDs) are thought to account for almost 25% of all reported adverse drug reactions, primarily gastrointestinal (GI) toxicity. Selective cyclo-oxygenase-2 (COX-2) inhibitors have been shown to preferentially inhibit activity of the COX-2 enzyme, which maintains anti-inflammatory activity but reduces GI toxicity. ⋯ Prescribers are more likely to switch older female patients and those with a past history of peptic ulcers from non-selective NSAIDs to COX-2 inhibitors. This suggests that doctors take risk factors into consideration when prescribing NSAIDs. The relatively low rate of switching may suggest that prescribers still have concerns over the place of COX-2 inhibitors and reserve their use to those patients particularly at risk of NSAID-induced GI toxicity.

Comparative StudyPerception of the risk of gastrointestinal adverse drug reactions with non-steroidal anti-inflammatory drugs (including coxibs): differences among general practitioners, gastroenterologists and rheumatologists.
To compare the perception of risk of gastrointestinal adverse drug reactions (ADRs) with non-steroidal anti-inflammatory drugs (NSAIDs) (including coxibs) in general practitioners, gastroenterologists and rheumatologists. ⋯ This study shows differences in the perception of risks of gastrointestinal ADRs. Rheumatologists systematically considered NSAIDs as less harmful than general practitioners and gastroenterologists did. In contrast, the widely demonstrated difference in gastrointestinal risk among the different groups of NSAIDS (with, for example, a higher risk for oxicams) was not pointed out by the three studied groups of physicians. There are differences in the perception of gastrointestinal risks of NSAIDs (including coxibs) among physicians according to their medical education and medical specialisation.
