Plain-English summary

A dog diagnosed with pituitary-dependent hyperadrenocorticism (a hormone disorder) may show symptoms like increased thirst, frequent urination, and a pot-bellied appearance. Two common medications for this condition are mitotane and trilostane. While mitotane has been used for a long time, it can have serious side effects, making trilostane a more appealing option for many veterinarians due to its simpler administration and fewer side effects. Both treatments can be effective, but it's important for pet owners to work closely with their vet to monitor their dog's health during treatment.

Abstract

Pituitary-dependent hyperadrenocorticism is a common endocrine disorder in dogs in the United States. Once a diagnosis is established, a decision must be made whether or not to pursue treatment, and if so, which medication to use. Historically, mitotane (Lysodren, o,p'-DDD, Bristol-Myers Squibb, New York) has been the most commonly used treatment for medical management. Its use is complicated and comes with many potential side effects, making many practitioners wary of its use. Recently, trilostane has been proven to be an effective treatment of pituitary-dependent hyperadrenocorticism and is approved for use in other countries. Treatment with trilostane is somewhat simpler and the incidence of side effects seems to be less when compared with mitotane therapy. Either treatment can be a safe and effective method of treatment for pituitary-dependent hyperadrenocorticism when the practitioner and client are well educated regarding their use and an appropriate monitoring protocol is used.
