[Criteria for the selection of drugs for the pathogenetic treatment of Itsenko-Cushing disease].

The authors presented the results of a study of the level of corticotropin and cortisol in the blood at different time after a single intake of peritol or parlodel in 48 patients with Icenko-Cushing disease at the active stage. Corticotropin and cortisol concentrations were determined by radioimmunoassay with the help of standard kits. The study showed a different sensitivity of patients with Icenko-Cushing disease to peritol and parlodel. According to the expression of the reaction of the hypophyseal-adrenal system all the patients were divided into the following groups: with a noticeable reaction to one or both drugs, with a slightly noticeable decrease in the level of hormones or a paradoxical reaction to the drugs. A single test with inhibitors of hypophyseal corticotropic function provided an opportunity for an individual choice of an effective drug for pathogenetic treatment of patients with Icenko-Cushing disease. The optimum time for blood examination to determine the concentration of corticotropin was 1 and 2 hrs, the level of cortisol 2-4 hrs after the intake of peritol and parlodel.
