L-5HTP was tested versus placebo in a double-blind crossover study of
27 migraine children aged 612 years, who recorded their headaches
in a headache diary for 1 month. Twenty-one patients subsequently
started the trial. The mean daily dose of L-5HTP was 5 mg/kg body
weight, and each treatment period with either L-5HTP or placebo
lasted 12 weeks. In group A (L-5HTP-placebo; 10 patients) and group B
(placebo-L-5HTP; 11 patients) both L-5HTP and placebo led to a
significant reduction of the migraine index and frequency of migraine
attacks during the 3rd month of each treatment period. However, we
found a treatment x period interaction because the efficacy
determinants decreased significantly during the first and the second
treatment periods in both groups irrespective of the sequence of
treatments. No differences were found between L-5HTP (first period of
group A) and placebo (first period of group B).
