title: [Clinical data on COX-1 and COX-2 inhibitors: what possible alerts in pharmacovigilance?].
abstract: Adverse effects of NSAIDs are serious, mainly related to gastrointestinal bleeding, and throughout the world cause about 260,000 hospitalizations and 26,000 deaths a year, but each day at least thirty million patients take NSAIDs. Selective COX-2 inhibitors (i.e. celecoxib, rofecoxib) have demonstrated in clinical trials better gastrointestinal tolerability but their safety in patients with active ulcer, cardiovascular or renal disease has still to be further investigated. When their long-term safety has been established by pharmacovigilance studies they could be prescribed in the at-risk population or for other indications, including pre-term labour, colorectal cancer and Alzheimer's disease, provided they have shown efficacy and safety in controlled trials.
