Cortisone in treatment of bronchial asthma.

Twenty patients with intractable asthma were treated with cortisone on various dosage schedules. Results indicated that a rapid improvement in the asthmatic state may be expected in four to five days with high level dosage of the hormone-usually a total dose exceeding 200 mg. per day at the beginning. If treatment is discontinued after a week, relapse usually will occur within a period of eight days. If small doses are given two or three times weekly, following initial response, relapse may not occur for 20 or 30 days. The interspersed administration of ACTH during an attempt to discontinue cortisone apparently was of no value. It therefore appears that cortisone control of intractable asthma is dependent on large dosage until clinical improvement is obtained, then approximately 100 mg. two or three times a week for maintenance of a reasonable state of health.
