Oral lysine clonixinate in the acute treatment of migraine: a double-blind placebo-controlled study

Several oral nonsteroidal anti-inflammatory drugs (NSAIDs) are effective to treat migraine attacks. Lysine clonixinate (LC) is a NSAID derived from nicotinic acid that has proven to be effective in various pain syndromes such as renal colic and muscular pain. The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of oral LC compared to placebo in the acute treatment of migraine. Sixty four patients with the diagnosis of migraine, according to the IHS criteria, were studied prospectively. Patients received LC or placebo once the headache reached moderate or severe intensity for 6 consecutive attacks. With regard to the moderate attacks, LC was superior than placebo after 1, 2 and 4 hours. The consumption of other rescue medications after 4 hours was significantly higher in the placebo group. With regard to the severe attacks, there was no difference between the active drug group and the placebo group concerning headache intensity and consumption of other rescue medications. We conclude that the NSAID lysine clonixinate is effective in treating moderately severe migraine attacks. It is not superior than placebo in treating severe migraine attacks

Características clínicas da migrânea transformada / Clinical features of transformed migraine

Grande parte dos pacientes com cefaléia diária atendidos em clínicas especializadas apresentam história de migrânea. Alguns autores referem-se a esta cefaléia como migrânea transformada, destacando sua menor intensidade e características clínicas diferentes das migrâneas. O objetivo deste estudo foi avaliar a apresentação clínica da cefaléia diária em pacientes com história de migrânea antes de sua transformação em diária. Foram estudados retrospectivamente 215 pacientes. Observamos que porcentagem elevada dos pacientes com migrânea transformada apresentava dor em pressão ou peso, característica da cefaléia tipo tensional crônica. O caráter latejante ainda permaneceu como um achado importante, especialmente naqueles pacientes com ataques intermitentes de migrânea típica.
