[Controlling carbohydrate content in antiepileptic medications for children on a ketogenic diet]

Introduction: patients who follow a ketogenic diet for the control of epileptic seizures must carry out a strict control of carbohydrates from the foods they eat and the medicines they are prescribed. In the initiation of a ketogenic diet and when a doctor prescribes a new medication, it is necessary to select the most appropriate pharmaceutical form so that the supply of excipients in the form of carbohydrates from the drugs is minimized. Objectives: the goal of the present paper was to compile a list of carbohydrate and caloric contents in antiepileptic drugs commonly used in pediatric neurology. Methods: in each medication included in the list, the content of excipients considered carbohydrates and derivatives that could influence the patient's ketosis was reviewed. The caloric content from carbohydrates and polyols in each medication was calculated. Results: the table provides the total carbohydrate and caloric content for antiepileptic medications in pediatric patients consuming the ketogenic diet. Conclusions: this table is intended to be a useful tool to help clinicians select a pharmaceutical form that is less likely to affect the ketogenic diet. Additionally, knowing the carbohydrate content of a new medication will allow adjustment of the diet to maintain ketosis.
