Vetoryl capsules for dogs - Cushing's Disease treatment

Dog Cushing
What is Vetoryl?

Vetoryl is a drug that is used in the treatment of Hyperadrenocorticism (Cushings) which occurs when the body is producing an excess of the steroid hormone cortisol. Vetoryl contains the active ingredient, Trilostane. Vetoryl is manufactured Dechra Veterinary Products and comes in blister packs of 30 capsules. Vetoryl is available in four different sized capsules to ensure accurate dosing whatever the size of dog involved. The total daily dose will be determined by your vet and is given once daily, usually in the morning.
What is Vetoryl used for?

Vetoryl is used to treat Cushing’s disease in dogs. Cushings occurs when the adrenal glands produce too much of the steroid hormone cortisol. Cortisol is usually released at times of stress but a prolonged excess is detrimental. This excess can be either because of a mass secreting cortisol from the adrenal gland or because the brain is releasing an excess of the hormones that stimulate the adrenal glands. Trilostane blocks the pathway of reactions that make cortisol which reduces the amount of it in the bloodstream and so reduces the clinical signs associated with Cushings. These clinical signs include excessive thirst and urination and a pot bellied appearance. Close monitoring is essential to make sure that the Vetoryl is not suppressing the levels of cortisol too far as some cortisol is still needed by the body to respond to stressful situations.
