Cyproheptadine stimulated prolactin release in the young turkey (Meleagris gallopavo).

Abstract

Cyproheptadine (CHD) at doses of .1 to 10.0 mg/kg body weight produced a dose-related elevation in prolactin (PRL) and no change in luteinizing hormone (LH) levels. Cyproheptadine pretreatment failed to depress the quipazine (serotonin agonist)-induced PRL rise. Rather than inhibiting the serotonergic induction of PRL release in the young turkey, CHD exerted a stimulatory influence on PRL release through another mechanism.
