Zacopride was found to significantly increasealdosterone levels in human subjects for 180 minutes at a dose of 400 micrograms. It is thought to do this by stimulating the 5-HT4 receptors on the adrenal glands. Zacopride also stimulated aldosterone secretion when applied to human adrenal glandsin vitro. No significant changes were observed inrenin,ACTH, orcortisol levels.[2]
Zacopride has been tested in clinical trials for the treatment ofschizophrenia, but was found unsuccessful.[10]
