Cabergoline

개요Cabergoline is a potent, selective, and long-lasting dopamine D2 receptor agonist launched in 1993 in Belgium as a prolactin inhibitor. A single 1 mg dose of cabergoline effectively prevents puerperal lactation for up to 14 days, remarkably superior to other drugs that require a daily regimen. It has a low rate of rebound breast activity and good tolerability. Cabergoline is also in clinical trials for Parkinson's disease, breast cancer, and hyperprolactinaemia.

용도Cabergoline is an ergot derivative and a dopamine D2-receptor agonist (1,2,3). It inhibits the secretion of prolactin and growth hormone.

일반 설명Cabergoline, (6aR,9R,10aR)-7-allyl-N-(3-(dimethylamino)propyl)-N-(ethylcarbamoyl)-4,6,6a,7,8,9,10,10a-octahydroindolo[4,3-fg]quinoline-9-carboxamide (Dostinex), is a white powder soluble inalcohol, chloroform, and N,N-dimethylformamide; slightlysoluble in acidic solutions and in n-hexane; and insoluble inwater. Following oral administration, peak plasma concentrationsare reached within 2 to 3 hours. Cabergoline ismoderately bound to plasma proteins in a concentrationindependentmanner. The absolute bioavailability of cabergolineis unknown. Cabergoline is extensively metabolizedby the liver, predominantly via hydrolysis of the acylureabond of the urea moiety. CYP450 metabolism appears to beminimal. The major metabolites identified thus far do not contribute to the therapeutic effect of cabergoline. Lessthan 4% is excreted unchanged in the urine. Fecal excretionrepresents the main route of cabergoline elimination. Thereare no reports of interactions of cabergoline with other antiparkinsonianagents. Clarithromycin may elevate theplasma concentration of cabergoline by the inhibition ofboth CYP3A4 and P-glycoprotein.Cabergoline is a potentD2 receptor agonist and is indicated for the treatment ofhyperprolactinemic disorders, either idiopathic or causedby pituitary adenomas.
