Mirataz is the first and only transdermal medication specifically developed, and FDA approved, for cats. Weight loss is the leading cause of visits to the veterinarian for cats. Mirataz, which is formulated with KindredBio's proprietary Accusorb technology, is applied topically to the cat's inner ear (pinna) once a day, providing a more attractive application route compared to oral administration. Mirataz is a serotonin (5HT2A, 5HT2C, and 5HT3) and histamine (H1) receptor antagonist, which has demonstrated body weight gain in cats experiencing weight loss. The product is classified as a weight gain drug and can be used in cats with various underlying diseases associated with unintended weight loss.
