Ketoconazole, an antiglucocorticoid drug, was administered to 10 hyper
cortisolemic depressed patients for up to 6 weeks. Three patients drop
ped out because of side effects or intercurrent illness. The remaining
seven had significant ketoconazole-associated decreases in serum cort
isol levels and in depression ratings. Antiglucocorticoid agents may b
e useful probes for investigating the sequelae of hypercortisolemia in
patients with major depression.
