Gastrointestinal tolerability of ibuprofen compared with paracetamol and aspirin at over-the-counter doses.
This multicentre, randomized, investigator-blinded, parallel-group study compared the gastrointestinal (GI) tolerability of ibuprofen, paracetamol and aspirin at over-the-counter doses for common pain indications. Patients (of whom 8633 were evaluable) took either ibuprofen up to 1200 mg daily, or paracetamol or aspirin, each up to 3000 mg daily, for 1-7 days. The main outcome was the proportion of patients with GI adverse events. There were significantly more patients who suffered GI adverse events, principally abdominal pain, dyspepsia, nausea and diarrhoea, with aspirin (18.5%) than with ibuprofen (11.5%), but the difference between ibuprofen and paracetamol (13.1%) was not significant. Significantly more of those patients with a history of non-ulcer GI disease (n = 371) developed GI adverse events than did those with no such history; the incidence of GI adverse events in both groups was lowest with ibuprofen. More women than men experienced GI adverse events (15.5% versus 12.8%). The higher incidence of GI adverse events with aspirin was evident from the first day of treatment. In conclusion, the GI tolerability of ibuprofen, at over-the-counter doses of up to 1200 mg daily for up to 7 days, was at least as good as that of paracetamol and significantly better than that of aspirin.
