ABT-724 is a drug which acts as a dopamine agonist, and is selective for the D₄ subtype.^[1] It was developed as a possible drug for the treatment of erectile dysfunction,^[2] although poor oral bioavailability means alternative drugs such as ABT-670 may be more likely to be developed commercially.^[3] Nonetheless, it continues to be used in scientific research into the function of the D₄ receptor.^[4]^[5]
