Review Comparative StudyReview of the analgesic efficacy of ibuprofen.
There is a clear relationship between single doses of ibuprofen over the range 50-400 mg and the peak analgesic effect and the duration of analgesia. The smallest clinically useful dose of ibuprofen is 200 mg. Ibuprofen 400 mg has been shown to be as effective as aspirin 600 or 900 mg/day in models of moderate pain but superior to aspirin or paracetamol in more sensitive models such as dental pain. ⋯ The combination of ibuprofen and hydrocodone is more effective than either drug alone in patients undergoing abdominal and gynaecological surgery. The absorption of ibuprofen acid is influenced by formulation, and certain salts of ibuprofen (lysine, arginine, potassium) and solubilised formulations have an enhanced onset of activity. These differences are clinically important, offering a shorter time to onset of relief of tension headache compared with paracetamol.

Review Randomized Controlled Trial Comparative Study Clinical TrialForty years of ibuprofen use.
Low-dose ibuprofen is as effective as aspirin and paracetamol for the indications normally treated with over-the-counter (OTC) medications and is associated with the lowest risk of gastrointestinal toxicity of any non-steroidal anti-inflammatory drug. By contrast, even low-dose aspirin is associated with an appreciable risk of gastrointestinal toxicity. Paracetamol is well tolerated and effective in treating mild to moderate pain but there is growing concern about a possible risk of gastrointestinal toxicity and a possible link with asthma in children. ⋯ Significant adverse events were more common with aspirin (10.1%) than ibuprofen (7.0%) (P<0.001) or paracetamol (7.8%). Significant gastrointestinal events were less frequent with ibuprofen (4.0%) than with aspirin (7.1%, P<0.001) or paracetamol (5.3%) (P=0.025). For every 100 patients treated, five more will experience significant adverse events if they are taking aspirin rather than ibuprofen, and four more than if they were taking paracetamol.
