Prolactin secretion is inhibited by -
Ans. is 'd' i.e., Bromocriptine o Prolactin is under predominant inhibitory control of hypothalamus through prolactin releasing inhibitory hormone (PRIH). o PRIH is a dopamine that acts on pituitary lactotrope D, receptor. So, Dopaminergic agonists decrease plasma prolactin levels. These agonists are : Dopamine Cobergoline Bromocriptine Apomorphine Dopaminergic antagonists and DA depleters will increase prolactin level Dopaminergic antagonists are : Dopamine depleters are : o Chlorpromazine o Reserpine o Haloperidol o Methyl dopa o Metoclopramide
Dopamine antagonist
GABA
Neurophysin
Bromocripitine
