Acarbose is an α-glucosidase inhibitor used as an anti-diabetic drug used to treat canine diabetes mellitus[1].

This oral medication appears to have reasonable efficacy at reducing hyperglycemia in dogs[2], with efficacy similar to metformin.

Few side-effects have been reported with this medication[3] and the recommended dose rate in dogs is 25 - 50 mg orally once daily[4].
