Vergleich der Wirksamkeit von 750 mg Valproat mit 75 Topiramat

Eine italienische Studie hat die prophylaktische Wirkung von 750mg Valproat mit der prophylaktischen Wirkung von 75mg Topiramat (Topamax©) in der Migräneprophylaxe verglichen. Dabei zeigte sich: Beide Medikamente sind wirksam, es konnte aber kein signifikanter Unterschied in der Wirksamkeit zwischen den beiden Medikamenten festgestellt werden.

OBJECTIVES:: The aim of this study was to compare the efficacy of sodium valproate and topiramate in treating chronic migraine. METHODS:: Forty-nine patients with chronic migraine were randomly assigned to 1 of 2 groups of treatment: 750 mg/day valproate or 75 mg/day topiramate. Efficacy variables were number of days with headache over a 30-day period and changes in Migraine Disability Assessment (MIDAS) scores at 3 months. RESULTS:: At baseline the 2 groups had similar numbers of days with headache and mean MIDAS scores. At the end of the treatment period, a significant reduction in 30-day headache frequency with respect to baseline (P < 0.00001) and a significant reduction in MIDAS scores (P < 0.00001) were recorded in both groups. There were no significant differences in beneficial effects between the 2 drugs. DISCUSSION:: Valproate and topiramate seem to be able to manage successfully chronic migraine without substantial differences in efficacy and tolerability. This affords clear practical advantages-in the event of failure of or intolerance for one treatment, the patient may be switched to the other.
