RESUMEN
La epilepsia resistente a fármacos es una condición que afecta a una proporción sustancial de pacientes tratados con los fármacos antiepilépticos disponibles, los que devienen refractarios a la terapia. Coincidentemente, los fármacos antiepilépticos han sido relacionados con procesos de estrés oxidativo (OS), lo cual puede impactar en la progresión de la enfermedad y ser relevante para el sucesivo desarrollo de fármacos. En esta revisión se analizan los procesos de OS vinculados a la epilepsia resistente a fármacos, que derivan en procesos de exitotoxicidad, neuroinflamación o disfunción mitocondrial, que se han manifestado en otros desórdenes neurológicos y particularmente en la epilepsia. Se muestran evidencias basadas en datos obtenidos mediante el estudio de la epilepsia del lóbulo temporal (ELT) en modelos animales, que derivan en daño a las proteínas, los lípidos y las defensas antioxidantes. Se incluye una vista general emergente sobre la relación del OS y los mediadores solubles involucrados de la inflamación y la escitotoxicidad. Además, se discuten nuevos abordajes terapéuticos, como los propuestos para complementar las terapias existentes o incluso nuevas estrategias para interferir los cambios crónicos inducidos por los ataques recurrentes para un mejor control de la progresión de la enfermedad.
