Randomized Controlled Trial Clinical TrialSelf-medication of a single headache episode with ketoprofen, ibuprofen or placebo, home-monitored with an electronic patient diary.
1. The objective of this study was to investigate the efficacy of home-medicated non-steroidal anti-inflammatory (NSAID) analgesics, using an electronic patient diary. Single doses of ketoprofen 25 mg and ketoprofen 50 mg were compared with ibuprofen 200 mg and placebo in the treatment of a single occasion of episodic tension-type headache, using a double-blind, randomized, parallel group design. 2. ⋯ Treatment of headache with ketoprofen can start with 25 mg, and possibly less. 6. Although a direct comparative study would be necessary to determine the relative benefits of the novel electronic patient diaries over traditional paper-and-pencil methods, this study has shown the usefulness of this newer technique to detect differences in efficacy between low doses of analgesics under ambulant conditions, with very limited loss of data. Electronic patient diaries appear to be an important new attribute for the efficacy assessment of self-medicated drugs.
