Abstract

Introduction: Topiramate and onabotulinumtoxin A have proven to be effective in chronic migraine with or without medication abuse according to recent criteria of the International Headache Society's Headache Classification.

Aims: To show that flunarizine is as effective as topiramate in cases of chronic migraine without medication abuse.

Patients and methods: We conducted a prospective, non-randomised, comparative study of two groups of patients paired by age and sex, with chronic migraine without abuse, who had been treated preventively for the first time with topiramate or flunarizine.

Results: Forty patients treated with flunarizine were assigned a patient of their same sex and age who was being treated with topiramate. The mean rate of reduction in intense migraines in the topiramate group was 59% and in the flunarizine group, 58.5% (p = 0.9444); the responder rate at four months of treatment did not show any significant differences either, the figures being 75% for topiramate and 70% for flunarizine (p = 0.6236). The mean reduction of other headaches in the topiramate group was 57% and in the flunarizine group, 64% (p = 0.4261); the responder rate at four months of treatment was similar in the two groups: 76%. The percentage of dropouts from treatment was higher with topiramate (19.5%) than with flunarizine (10%) (p = 0.3493). No serious side effects occurred in either of the groups. In all, 78.9% of the patients who took topiramate said they were satisfied with the drug versus 75% of those in the flunarizine group (p = 0.7903).

Conclusions: Flunarizine proved to be as effective as topiramate in the treatment of chronic migraine without medication abuse.

Title: Estudio comparativo de la efectividad del topiramato y la flunaricina en series independientes de pacientes con migraña cronica sin abuso de medicacion.

Introduccion. El topiramato y la onabotulinumtoxina A han mostrado ser eficaces en la migraña cronica con o sin abuso de farmacos segun los criterios recientes de la Clasificacion de Cefaleas de la Sociedad Internacional de Cefaleas. Objetivo. Demostrar que la flunaricina es tan efectiva como el topiramato en la migraña cronica sin abuso de farmacos. Pacientes y metodos. Estudio prospectivo, no aleatorizado, comparativo de dos grupos de pacientes con similar edad y sexo, con migraña cronica sin abuso, tratados preventivamente por primera vez con topiramato o flunaricina. Resultados. A 40 pacientes tratados con flunaricina se les asigno un paciente del mismo sexo y edad tratado con topiramato. La media de reduccion de las migrañas intensas en el grupo del topiramato fue del 59% y en el grupo de la flunaricina, del 58,5% (p = 0,9444); la tasa de respondedores al cuarto mes de tratamiento tampoco mostro diferencias significativas, ya que fue del 75% para el topiramato y del 70% para la flunaricina (p = 0,6236). La media de reduccion de otras cefaleas en el grupo del topiramato fue del 57%, y en el grupo de la flunaricina, del 64% (p = 0,4261); la tasa de respondedores al cuarto mes de tratamiento fue del 76%, similar en ambos grupos. El porcentaje de abandonos del tratamiento fue mayor con el topiramato (19,5%) que con la flunaricina (10%) (p = 0,3493). En ninguno de los dos grupos hubo efectos adversos graves. Un 78,9% de los pacientes que tomo topiramato presento satisfaccion con el farmaco frente al 75% del grupo de la flunaricina (p = 0,7903). Conclusion. La flunaricina mostro ser tan efectiva como el topiramato en el tratamiento de la migraña cronica sin abuso de farmacos.
