Using oral topiramate for primary generalized and focal-to-bilateral tonic-clonic seizures in patients 2 years of age and older: a review of the literature.

Abstract

Introduction: Topiramate is a drug belonging to the second generation of antiseizure arsenal, used to treat focal onset seizures without generalization, focal-to-bilateral tonic-clonic seizures, and primary generalized tonic-clonic seizures.

Areas covered: The narrative evaluation of topiramate's clinical research that has been published in this article focuses on the medication's effectiveness and safety when used to treat primary generalized and focal-to-bilateral tonic-clonic seizures. From their founding to the present, the databases MEDLINE, SCOPUS, EBSCO, and GOOGLE SCHOLAR were searched.

Expert opinion: Topiramate treatment has the obvious benefit of being effective in treating tonic-clonic seizures; nevertheless, it may have a drawback in that up to 56% of patients discontinue therapy due to its rather poor tolerability, particularly at doses exceeding 600 mg daily. Patients are most bothered by psychiatric and cognitive side effects, and then by appetite and weight decrease. While the onset of anorexia cannot be prevented by changing the dosage regimen, psychiatric and cognitive side effects can be mitigated by slowly titrating the topiramate dose.
