The study monitored plasma levels of valproic acid in 90 epileptic children over two years. Among 34 patients on sodium valproate monotherapy, 82% achieved complete seizure control with a mean plasma level of 65.1 micrograms/ml, while 18% experienced recurring seizures with higher plasma levels, suggesting resistance to the drug. Valproic acid was effective for absences, tonic-clonic seizures, and partial epilepsy. In combination with phenobarbital, 64% of 22 children achieved seizure control. In more severe cases treated with multiple anticonvulsants, only 35% achieved control. Side effects included increased appetite, gastrointestinal disturbances, transient hair loss, and tiredness, mostly at plasma levels above 70 micrograms/ml. A therapeutic range of 40-90 micrograms/ml was suggested.
