Trilostane/Vetoryl Information and Resources
Trilostane is the chemical name for a medication that effectively treats Canine Cushing's Disease. Worldwide, the only licensed veterinary version of trilostane is manufactured in the U.K. by the Dechra Group under the brand name of "Vetoryl." Vetoryl received FDA approval for sale in the U.S. beginning in 2009. Vetoryl is generally marketed in four dosage strengths: 10 mg., 30 mg., 60 mg., and 120 mg. capsules. In the U.S., 5 mg. capsules are also available.
All dosage strengths of brand name Vetoryl capsules are now sold in the U.S. by veterinarians and also via internet pharmacies. Additionally, several pharmacies in the U.S. are compounding and selling their own versions of trilostane for veterinary use. For members who obtain compounded trilostane, we encourage you to contact your pharmacy directly regarding the ongoing availability of specific dosage strengths.
