Anticholeretic effect of somatostatin in anesthetized dogs

Somatostatin, 0.2-1.0 microgram . kg-1 . min-1, was administered i.v. in 5 anesthetized dogs. Following 9-min infusions, hepatic bile output was found to decrease by approximately 50% after a latency of 6 min. The mode of action suggests that somatostatin inhibits hormone-induced bile output.
