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.
A prolactinoma is a tumor of the pituitary gland that produces the hormone prolactin.It is the most common type of functioning pituitary tumor. [1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood (hyperprolactinemia), or due to pressure of the tumor on surrounding brain tissue and/or the optic nerves.
[58] [59] If the prolactinoma does not initially respond to dopamine agonist therapy, such that prolactin levels are still high or the tumor is not shrinking as expected, the dose of the dopamine agonist can be increased in a stepwise fashion to the maximum tolerated dose. [3] Another option is to consider switching between dopamine agonists.
Prolactin and its receptor are expressed in the skin, specifically in the hair follicles, where they regulate hair growth and moulting in an autocrine fashion. [ 29 ] [ 30 ] Elevated levels of prolactin can inhibit hair growth, [ 31 ] and knock-out mutations in the prolactin gene cause increased hair length in cattle [ 32 ] and mice. [ 30 ]

These side effects can be reduced or eliminated if medication is started at a very low dose at bedtime, taken with food, and gradually increased to the full therapeutic dose. Bromocriptine lowers GH and IGF-1 levels and reduces tumor size in fewer than half of people with acromegaly. Some people report improvement in their symptoms although ...
Hypopituitarism is the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. [1] [2] If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. [3]
