Vetoryl (trilostane) Capsules for Cushing's Disease in Dogs

Managing Cushing’s Disease in dogs centers on controlling the level of cortisol in your dog’s bloodstream. Trilostane, the active ingredient in prescription Vetoryl, effectively regulates cortisol in the adrenal gland easing symptoms of the disease in dogs.

  •  Helps control cortisol production
  •  Effective in treating adrenal-dependent and pituitary-dependent forms of the disease
  •  Reduces symptoms of the disease over time
  •  Available in four dosage levels


Cushing’s Disease, or hyperadrenocorticism, causes a range of physical challenges for dogs from weakened immune systems to hair loss. Dogs with the disease have too much of the hormone cortisol, produced in times of stress, in their bloodstream. Prescription Vetoryl’s active ingredient, trilostane, helps regulate cortisol production in the adrenal gland and reduces disease symptoms. This medication is also effective for dogs with the pituitary form of Cushing’s Disease. With regular administration of Vetoryl you should see improvements in your dog’s condition in a matter of weeks.
