We have analyzed pharmacoeconomical indicators in the treatment of idiopathic (generalized and focal) epilepsy in children and adolescences in an ambulatory treatment/diagnostic center of a big industrial city. In the total structure, focal epilepsy made up 41.73% (255 patients, 128 boys (50.2%) and 128 girls (49.8%)). Generalized forms were diagnosed in 61.96% (n=158) and partial forms - in 37.6% (n=97%) patients. Minimal direct and indirect costs for one patient were calculated for patients in remission and did not depend on the form of epilepsy. The costs increased by a magnitude of two or more for treatment efficiency 50% and by 3 times for insufficient efficiency of treatment of different forms of epilepsy. In case of a loss of control of seizures, indirect costs exceeded the economy of direct costs. Adequate treatment of idiopathic epilepsy in children is economically profitable because it allows to improve quality of life of a child and maintain manpower resources in the nearest future.
