Study of Valproate in Young Patients Suffering From Epilepsy

Therapeutic Follow-up Observational Study and Population Kinetics Ancillary Study of Valproate Microgranules (Micropakine® SR) in Patients Aged Between 6 Months and 15 Years Suffering From Epilepsy.

Main objective: Therapeutic follow-up study Evaluate the clinical and biological safety of valproate administered as microgranules, under standard prescription conditions, with therapeutic follow-up and individual dosage adjustment, using valproate plasma concentrations and antiepileptic comedication as well as biological assays.

Secondary objectives: Ancillary population kinetics study

• Estimate the pharmacokinetic parameters of valproate administered as microgranules under standard therapeutic conditions within the population studied, from the therapeutic follow-up data.
• Evaluate the influence of individual characteristics on the pharmacokinetic parameters.
• Describe the relationship between plasma concentrations and adverse events for valproate and the main anti-epileptic comedications.

Inclusion Criteria:

• Children aged between 6 months and 15 years.
• Suffering from any type of epilepsy.
• Receiving at the time of inclusion valproate in the form Micropakine® SR 20 to 30 mg/kg/d by oral route, in 2 daily administrations and at most two other antiepileptic drugs (an antiepileptic benzodiazepine treatment taken daily or on demand more than 2 times weekly, must be considered as an antiepileptic treatment).
• Followed by hospital paediatricians or neuropaediatricians.
• For whom the consent has been signed by the parents or the holders of parental authority and if possible by the child him/herself.
• For whom the parents or legal guardian do not have any language or cultural obstacle for understanding the study.
