Randomized Controlled Trial Comparative Study Clinical Trial
Ketoprofen, paracetamol and placebo in the treatment of episodic tension-type headache.
The aim of the study was to assess the efficacy and tolerability of a single oral dose of ketoprofen 25 mg in comparison with single doses of ketoprofen 2 x 25 mg, paracetamol 500 mg and 1,000 mg, and placebo in the treatment of episodic tension-type headache. The study was conducted as a single centre, double-blind, randomized, placebo-controlled, five-period, within-patient comparative trial in outpatients with episodic tension-type headache according to the International Headache Society's diagnostic criteria. Each patient had to treat five attacks of episodic tension-type headache with a single dose of each of the tested medications with a minimum interval of 72 h between two attacks. ⋯ Neither of the paracetamol groups differed from the placebo group. Only a few adverse events were reported, usually of mild or moderate severity, with no difference between the treatments. Ketoprofen 50 mg may be considered an effective and well tolerated analgesic in the treatment of episodic tension-type headache of moderate or severe intensity.
