Ketoprofen (Orudis) twice daily dosage in arthritis and tissue injuries: a general practice study.

In a general practice study using ketoprofen (Orudis) in a twice-daily dosage regimen for the treatment of patients with articular and non-articular rheumatic conditions, data were collected on 2,644 patients, over one-third of whom had been previously treated with other anti-rheumatic preparations. More than 80% showed a clinical improvement and the overall incidence of side-effects was relatively low. Three patients suffered a haematemesis--the most serious side-effect encountered. It was concluded that 50 mg or 100 mg twice-daily therapy was equally as effective as the 50 mg thrice daily regimen previously recommended and that the tolerability of ketoprofen was not adversely affected by this concentration of the daily requirement.
