title: [COX-2 inhibitors: a new treatment in rheumatic diseases].
abstract: Progressive increase of the average lifespan pushed up the number of the elderlies in the population. The subsequent spread of degenerative conditions such as osteoarthritis has inflated the request of NSAID despite their frequent toxicity. Side effects of NSAID are sometimes severe and mainly target gastrointestinal tract, renal and platelets function. It has been estimated that around 70% of the patients treated with NSAID develop some degree of gastric damage, ranging from aspecific dyspeptic syndromes to ulcerative diseases. Drugs are now available that selectively inhibit the cyclooxygenase-2: this enzyme is involved in the synthesis of prostaglandins during the inflammatory response. These new drugs have opened new perspectives in the treatment of arthritis; they allow COX-1 to work regularly, so that those prostaglandins that are involved in the maintenance of a regular function of the gastrointestinal tract mucosa and of the platelets. Celecoxib was the firstborn of these new drugs. Differently from FANS, COXIB has got less side effects on gastrointestinal tract and platelets function. Based on the evidence of the more recent clinical experience COXIB has to be recommended; in particular celecoxib, at a schedule of 200-400 mg/die, was shown to be highly effective in the symptomatic treatment of osteoarthritis and rheumatoid arthritis.
