Subacute toxicity of hydrocortisone 17-butyrate 21-propionate (HBP) was studied in rats. HBP was percutaneously given to rats with 0.1% and 0.5% creame (0.1% HBP-C, 0.5% HBP-C) and ointment (0.1% HBP-O, 0.5% HBP-O) at the daily dose level of 150 mg per 100 g body weight for 1 month. Rats receiving HBP-C and HBP-O showed some dose-dependent symptoms such as the suppression of body weight gain, emaciation, decrease in the number of white blood cells, hemoglobin, hematocrit and serum total cholesterol level, regressive changes in adrenals, skin, lymphatic and hematopoietic tissues, which are known as toxic effects of synthetic corticosteroids. These symptoms were comparatively high toxic in male rats and in cream groups, and almost disappeared in rats elapsed recovery time of 1 month after withdrawal of HBP.
