AGN 201904 is a slowly absorbed, acid-stable pro-proton pump inhibitor (pro-PPI) rapidly converted to omeprazole in the systemic circulation giving a prolonged residence time. AGN-201904 is a proton pump inhibitor; AGN-201904-Z is the sodium salt; AGN-201904 is an omeprazole prodrug. AGN 201904 produced a significantly greater and more prolonged acid suppression than esomeprazole, and nocturnal acid suppression was more prolonged over all 5 days. AGN 201904 should provide true once-a-day treatment and better clinical efficacy than current PPIs.
