Bromocriptine
medication which has significant effects on dopamine levels in the brain
Bromocriptine, sold under the brand name Parlodel among others, 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.
It was patented in 1968 and approved for medical use in 1975.
Medical uses
Bromocriptine is used to treat acromegaly and conditions associated with hyperprolactinemia like amenorrhea, infertility, hypogonadism, and prolactin-secreting adenomas. It is also used to prevent ovarian hyperstimulation syndrome and to treat Parkinson's disease.
Since the late 1980s it has been used, off-label, to reduce the symptoms of cocaine withdrawal but the evidence for this use is poor. Bromocriptine has been successfully used in cases of galactorrhea precipitated by dopamine antagonists like risperidone.
A quick-release formulation of bromocriptine, Cycloset, is also used to treat type 2 diabetes. When administered within 2 hours of awakening, it increases hypothalamic dopamine level. That results to a significant weight loss as well as decreases in blood glucose levels, hepatic glucose production, and insulin resistance. It therefore acts as an adjunct to diet and exercise to improve glycemic control and cardiovascular risk.
This brief starts where responsible research should: with the source description of “Bromocriptine” as medication which has significant effects on dopamine levels in the brain. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as medication which has significant effects on dopamine levels in the brain. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q413581. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1968 and 1975.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
