Treatment of hyperadrenocorticism (HAC) may be achieved by surgery (adrenalectomy or trans-sphenoidal hypophysectomy), pituitary irradiation, or medical treatment. Surgery and radiotherapy are complicated procedures available only at a few specialty centers, therefore medical treatment is often the most practical and approachable treatment choice. VETORYL® Capsules (trilostane) are the only FDA approved treatment available for both pituitary-dependent hyperadrenocorticism (PDH) and adrenal-dependent hyperadrenocorticism (ADH) in the United States. Although the daily administration of VETORYL Capsules does not offer a medical cure for Cushing’s syndrome, it may allow the disease to be managed successfully, enhancing the dog’s vitality and quality of life.
