Cabergoline is a long-acting dopamine D2 receptor agonist that inhibits prolactin secretion by the anterior pituitary gland.
Dopamine receptor agonist; exhibits high affinity for D2 and D3 receptors, and moderate affinity for D1 and D4 receptors.
0.25 mg orally twice weekly, up to 1 mg twice weekly; for hyperprolactinemia, initial 0.25 mg twice weekly, titrate by 0.25 mg every 4 weeks based on prolactin levels.
Immediate-release: Initial 0.25 mg orally three times daily; titrate weekly by 0.25 mg per dose to a total daily dose of 3 mg; max 24 mg/day. Extended-release: Initial 2 mg orally once daily; titrate by 2 mg/day at weekly intervals; max 24 mg/day.

Terminal elimination half-life is 63-68 hours in healthy subjects, allowing for once- or twice-weekly dosing. In hepatic impairment, half-life may be prolonged.
Terminal elimination half-life: approximately 5-6 hours in young healthy adults, extending to 7-9 hours in elderly patients. Clinically, dosing is typically three times daily due to this short half-life.
Approximately 60-70% of the dose is excreted in feces (primarily as unchanged drug and metabolites), with about 20-30% excreted renally (mostly as metabolites).
Primarily renal: approximately 90% of the dose is excreted in urine, with about 60% as unchanged drug and 30% as metabolites. Fecal excretion accounts for about 10%.
