[Influence of citalopram selective serotonin reuptake inhibitor on circadian rhytms of excretory function of the kidneys].

In experiments on the white rats it was established that the citalopram in dose 5 mg/kg significantly affects the circadian rhytms of excretory function of kidneys, especially at night. We conclude that serotonin, which content is increased by citalopram, may serve as a neurotransmitter in circadian rhytms regulation.
