Missing In Action

Generic substitution of antiepileptic drugs is an issue that is gathering a lot of attention in the neurology community but is not receiving much attention within pharmacy. Several proposals have been drafted that restrict a pharmacist's decision-making in generic substitution. These proposals highlight concerns about the pharmacy community related to generic substitution. Careful consideration needs to be given to these issues by pharmacists and pharmacy professional organizations. Unless pharmacy as a profession takes strong positions in support of a pharmacist's ability to make decisions about pharmacotherapy and addresses many of the pharmacy-related problems of generic substitution, policies that negatively impact pharmacy will be established.

Patients With Epilepsy

ABSTRACT As patent protection ends for the next generation of antiepileptic drugs (AEDs), a complex debate continues over generic substitution of AEDs. On one hand, generic drug formulations provide cost savings for patients and society. On the other hand, patients with epilepsy and physicians are wary about the adequacy and efficacy of the Food and Drug Administration's (FDA) standards for generics. This article reviews current and proposed bioequivalence test procedures, summarizes new generic AED formulations and their costs, and discusses potential pitfalls in the current standards. These shortcomings include certain pharmacokinetic factors and clinical pharmacologic factors that may affect bioequivalence of generic AEDs, and statistical limitations of the standards. While the drug concentration differences between the brand name drug and each generic formulation are unlikely to be substantial, the differences with generic-to-generic switches will be greater and potentially clinically significant. Conversely, owing to their more favorable pharmacokinetic profile, newer AEDs may be less prone to problems with generic substitution than older ones. Unfortunately, very few data are available to guide decisions regarding what is best for an individual patient. Based on new prediction methods, generic substitution should be safe for many patients but identifying them ultimately requires more rigorous study.
