Fedovapagon is primarily used in the treatment of nocturia, a condition characterized by the need to urinate frequently during the night. It works by selectively stimulating vasopressin receptors in the kidneys, which helps to reduce urine production and allows for longer periods of uninterrupted sleep. This makes it particularly beneficial for individuals who experience disrupted sleep patterns due to nocturia. Additionally, it may be explored for other conditions related to fluid balance and diuresis, though its primary application remains focused on managing nocturnal urination.
