Cyproheptadine 34-48 prolactin Rattus norvegicus 127-136 7426830-0 1980 Metergoline and cyproheptadine suppress prolactin release by a non-5-hydroxytryptaminergic, non-dopaminergic mechanism. Cyproheptadine 16-30 prolactin Rattus norvegicus 40-49 2435887-5 1987 Both CYPRO and 5,7-DHT attenuated the PRL response to morphine in adult but not neonatal rats. Cyproheptadine 5-10 prolactin Rattus norvegicus 38-41 3031276-6 1987 PRL secretion induced by these serotonergic agents was blocked by cyproheptadine, a serotonin receptor antagonist.
