Inhibition of prolactin secretion by low-dose dopamine infusion in patients with hyperprolactinaemia.


Dopamine inhibits the secretion of prolactin from the pituitary. We have examined the relation between plasma dopamine and serum prolactin in 12 patients with hyperprolactinaemia during the infusion of dopamine at low doses (0.01, 0.1 and 1 microgram/kg/min). Plasma dopamine levels were raised from less than 100 pg/ml at the lowest rate of infusion to more… (More)
