Capromorelin tartrate is primarily used in veterinary medicine as an appetite stimulant and growth promoter, particularly in dogs and cats. It works by mimicking the action of ghrelin, a hormone that stimulates hunger, making it beneficial for animals experiencing appetite loss due to illness, aging, or recovery from surgery. Additionally, it has been explored for its potential to improve muscle mass and overall body condition in aging or debilitated pets. In some cases, it is also studied for its potential applications in treating cachexia or muscle wasting in humans, though this remains under research. Its ability to enhance growth hormone secretion makes it a valuable tool in managing weight and promoting recovery in animals.
