[Tiapride in the treatment of chronic headache (author's transl)].

The therapeutic efficacy of tiapride in chronic headache (300 mg/day orally during 30 days) was studied in a doubleblind trial in a group of 50 patients, 40 of them with so-called "mixed headache", and 10 with classical migraine. The results were subjected to statistical analysis. 65% of treated patients had clinical benefit in the intensity and frequency of headaches. The mode of action of this drug is discussed, together with the involvement of several monoaminergic systems in the genesis of headache. The action of tiapride appears to be indirectly dopaminomimetic as it operates by a blockade of dopaminergic inhibitors receptors.
