Safety
- Toxicity
- An ergot alkaloid derivative that exhibits potent dopamine agonist properties, particularly at D2 dopamine receptors. Bromocriptine, like dopamine, inhibits prolactin release from the pituitary and so is used in endocrine disorders, such as hyperprolactinemia. It is also used in the treatment of Parkinson’s disease. A large “first-pass” effect is seen with bromocriptine, and peak concentrations occur about 1.5-3 h after ingestion, with a half-life of about 3 h. Nausea, vomiting, and orthostatic hypotension are among the acute adverse effects. Long-term use has been associated with dyskinesias, constipation, psychoses, digital spasm, and erythromelalgia. The LD50 in rabbits exceeds 1 g/kg, p.o., and 12 mg/kg, i.v.

Bromocriptine Chemical Properties,Usage,Production
Chemical Properties
Crystals.
Originator
Parlodel,Sandoz,UK,1975
Uses
Enzyme inhibitor (prolactin).
Uses
Bromocriptine, a dopaminomimetic that is a dopamine D2 receptor agonist, possesses expressed antiparkinsonian activity. It is used for treating all phases of idiopathic and postencephalic Parkinsonism.
Definition
An semisynthetic ergotamine alkaloid derivative and powerful dopamine D2 agonist. It inhibits prolactin secretion and release from the pituitary and retards tumor growth.
Manufacturing Process
A solution of 3.4 grams of N-bromosuccinimide in 60 cc of absolute dioxane is
added drop wise in the dark, during the course of 5 minutes, to a stirred
solution, heated to 60°C, of 9.2 grams of ergocryptine in 180 cc of absolute
dioxane. The reaction mixture is stirred at this temperature for 70 minutes
and is concentrated to a syrup-like consistency in a rotary evaporator at a
bath temperature of 50°C. The reaction mixture is subsequently diluted with
300 cc of methylene chloride, is covered with a layer of about 200 cc of a 2 N
sodium carbonate solution in a separating funnel and is shaken thoroughly.
The aqueous phase is extracted thrice with 100 cc amounts of methylene
chloride. The combined organic phases are washed once with 50 cc of water,
are dried over sodium sulfate and the solvent is removed under a vacuum.
The resulting brown foam is chromatographed on a 50-fold quantity of
aluminum oxide of activity II-III with 0.2% ethanol in methylene chloride as
eluant, whereby the compound indicated in the heading is eluted immediately
after a secondary fraction which migrates somewhat more rapidly than the
fractions containing the heading compound. The last fractions to leave the
aluminum oxide contain varying amounts of starting material together with
the heading compound, and may be subjected directly, as mixed fractions, to
an afterbromination in accordance with the method described above. The
fractions containing the pure heading compound are combined and crystallized
from methyl ethyl ketonehopropy1 ether. Melting point 215°-218°C
(decomp.), [α]D
20-195° (c = 1 in methylene chloride).

Therapeutic Function
Prolactin inhibitor
World Health Organization (WHO)
Bromocriptine, a semisynthetic ergot alkaloid derivative and prolactin inhibitor was introduced into medicine in 1976. It is used in the prevention of lactation, but because of the risk of rebound effect and since only 10% of women benefit therapeutically from such intervention, the United States Food and Drug Administration has requested manufacturers to no longer indicate preparations containing bromocriptine for this purpose. The World Health Organization is not aware of similar action having been taken elsewhere.
Hazard
Poison; teratogen; developmental abnor- malities of the respiratory system,musculoskeletal system, rogenital system, craniofacial area, and body wall; teratogen; mutagen; questionable car- cinogen; tumorigen; causes nausea, vomiting, orthostatic hypotension; constipation, dyskinesias, psychoses, digital spasm, erythromelalgia.
Mechanism of action
Bromocriptine is absorbed after oral administration, but approximately 90% of a dose undergoes extensive first-pass hepatic metabolism, with the remainder hydrolyzed in the liver to inactive metabolites that are eliminated mostly in the bile. The half-life is relatively short (~3 hours).
Clinical Use
Bromocriptine is an ergot peptide derivative that is a partial agonist at D1-type and a full agonist at D2-type postsynaptic dopamine receptors, usually given in combination with levodopa therapy. It was the first direct dopamine receptor agonist used in treatment of Parkinson's disease after its development as an inhibitor of prolactin release (via activation of anterior pituitary D2 receptors). At low doses (typically 1–5 mg/day), bromocriptine is an effective prolactin inhibitor, and at higher doses (typically 10–20 mg/day), the antiparkinsonism and mood-elevating effects of bromocriptine become apparent.
Side effects
Bromocriptine has a number of undesirable side effects, even causing mental disturbances in long-term use.
Synthesis
Bromocriptine, 2-bromoergocriptine (10.1.13), is a semisynthetic derivative of a natural ergot alkaloid, ergocriptin (a derivative of lysergic acid), which is synthesized by bromination of ergocriptin using N-bromosuccinimide [18,19].
Drug interactions
Potentially hazardous interactions with other drugs
Increased risk of toxicity with bromocriptine and
isometheptene.
Metabolism
Bromocriptine is extensively metabolised. It undergoes extensive first-pass biotransformation in the liver, reflected by complex metabolite profiles and by almost complete absence of parent drug in urine and faeces. In plasma the elimination half life is 3-4 hours for the parent drug and 50 hours for the inactive metabolites.The parent drug and its metabolites are also completely excreted via the liver with only 6% being eliminated via the kidney.
