Capromorelin is a potent ghrelin receptor agonist. Capromorelin is indicated for appetite stimulation in dogs. Plasma insulin-like growth factor-I (IGF-I) was elevated progressively over a 5-d course of daily oral dosing in dogs. In healthy older adults at risk for functional decline, administration of the capromorelin may improve body composition and physical function. Adverse events included fatigue, insomnia, and small increases in fasting glucose, glycosylated hemoglobin, and indices of insulin resistance.
