D 2 receptor agonists that are described as prolactin inhibitors include the approved medications bromocriptine, cabergoline, lisuride, metergoline, pergolide, quinagolide, and terguride and the never-marketed agent lergotrile. [3] Other dopamine agonists and dopaminergic agents, for instance levodopa (L-DOPA), can also inhibit prolactin ...

Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.
Bromocriptine, originally marketed as Parlodel and subsequently under many brand names, [1] is an ergoline derivative and dopamine agonist that is used in the treatment of pituitary tumors, Parkinson's disease, hyperprolactinaemia, neuroleptic malignant syndrome, and, as an adjunct, type 2 diabetes.
Cabergoline, sold under the brand name Dostinex among others, is a dopaminergic medication used in the treatment of high prolactin levels, prolactinomas, Parkinson's disease, and for other indications. [2] It is taken by mouth. Cabergoline is an ergot derivative and a potent dopamine D 2 receptor agonist. [3]
Prolactin secretion in the pituitary lactrotroph cells is normally suppressed by the brain chemical dopamine, which binds to dopamine receptors. Drugs that block the effects of dopamine at the pituitary or deplete dopamine stores in the brain may cause the pituitary to secrete excess prolactin without an inhibitory effect.
Dopamine agonists are currently the preferred medication for suppressing lactation, which work by suppressing prolactin production. [3] Cabergoline (Dostinex™) is currently most effective option currently available, as it is available as a single dose (as opposed to bromocriptine which must be taken twice daily for 2 weeks.) [4] It may be prescribed in the case of breast abscess.
It is an ergot derivative, which directly binds to the postsynaptic dopamine 2 receptors of anterior pituitary cells and inhibits the secretion of prolactin. [46] [47] Chemical structure of cabergoline. Cabergoline is a dopamine 2 receptor agonist which is also an ergot derivative. It functions similarly to bromocriptine but with higher ...
