Use of metyrapone to treat pituitary-dependent hyperadrenocorticism in a cat with large cutaneous wounds

Metyrapone, a drug that inhibits cortisol production, was used to lower plasma cortisol concentration and alleviate skin lesions caused by pituitary-dependent hyper-adrenocorticism in a cat. Plasma cortisol concentration was documented by ACTH stimulation test results. During metyrapone treatment, alopecia, thin skin, and large cutaneous wounds resolved. Metyrapone was administered orally at a dosage of 65 mg/kg of body weight, every 12 hours. Metyrapone may be used in conjunction with surgery in the management of pituitary-dependent hyperadrenocorticism in cats.
