[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.

5-OH-Tryptophane in migraine: clinical and neurophysiological considerations.

The clinical effects of the protracted treatment with 5-OH Tryptophane (5-HTP) of some patients with chronic migraine are compared with other patients with acetylsalicylic acid. The pain threshold was neurophysiologically determined in migraneous on patients whose response to 5-HTP therapy was specially good. The results with 5-HTP can be accounted for by an action of the substance on the serotonin turnover with activation of the serotoninergic antinociceptive system.
