Generic Name: bromocriptine (BROE moe KRIP teen)Brand Names: Parlodel
Bromocriptine is in a group of drugs called dopamine receptor agonists. It has some of the same effects as a chemical called dopamine, which occurs naturally in your body. Low levels of dopamine in the brain are associated with Parkinson's disease.
Bromocriptine also reduces your levels of prolactin, a hormone that is released from the pituitary gland.
Bromocriptine is used to treat certain conditions caused by a hormone imbalance in which there is too much prolactin in the blood (also called hyperprolactinemia). Signs of too much prolactin in the body include lack of sexual development in adolescents. Women may have missed menstrual periods, loss of interest in sex, hot flashes, infertility, or unexpected breast milk production and leakage from the nipples. Men may have enlarged breasts, decreased libido, decreased facial or body hair, and loss of muscle.
Bromocriptine is also used to treat these disorders when they are caused by brain tumors that can produce prolactin.
Bromocriptine is sometimes used together with surgery or radiation in treating acromegaly, a condition caused by a pituitary gland tumor that produces too much growth hormone.
Bromocriptine is also used to treat symptoms of Parkinson's disease, such as stiffness, tremors, muscle spasms, and poor muscle control.
