Cushing's syndrome Treatment Options
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.
A Few Facts about VETORYL Capsules:
- VETORYL Capsules contain trilostane, which selectively, and reversibly, inhibits the enzyme 3βs-hydroxysteroid dehydrogenase, which is involved in the synthesis of several steroids including cortisol and aldosterone
- At recommended dose rates, VETORYL Capsules tend to have a more selective effect on glucocorticoid production, however the potential inhibition of aldosterone must always be borne in mind by the attending clinician
- VETORYL Capsules reduce circulating cortisol levels, leading to improvement in many of the clinical signs of HAC
- VETORYL Capsules provide flexible and accurate dosing with five strengths, 5 mg, 10 mg, 30 mg, 60 mg and 120 mg capsules, allowing you to restore the dog’s vitality by reducing the clinical signs associated with HAC
- Available in blister packs of 30 capsules for ease of dispensing.
Important VETORYL Capsules dosage and administration information
- VETORYL Capsules should be administered orally, once daily, with food
- The starting dose is 1-3 mg/lb (2.2-6.7 mg/kg) once a day for the treatment of hyperadrenocorticism in dogs
- Start with the lowest possible dose based on body weight and available combinations of capsule sizes
- Once treatment has started, the owner should be advised to monitor the dog’s demeanor, appetite and water intake
- If the dog shows any signs of being unwell, advise the owner to stop treatment and contact a veterinarian immediately
- The dose should be titrated according to individual response as determined by monitoring of clinical signs, physical examination and laboratory test results (ACTH stimulation test and serum biochemistry, including electrolytes)
- Should symptoms not be adequately controlled for an entire 24 hour inter-dose period, consideration should be given to dosing with VETORYL Capsules twice daily
