CABERGOLINE vs PARLODEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cabergoline is a long-acting dopamine D2 receptor agonist that inhibits prolactin secretion by the anterior pituitary gland.
Dopamine D2 receptor agonist; inhibits prolactin secretion by binding to pituitary and hypothalamic D2 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.
Parkinson disease: initial 1.25 mg orally twice daily, increase by 2.5 mg/day every 2-4 weeks; usual range 15-30 mg/day. Hyperprolactinemia: initial 1.25-2.5 mg orally once daily, titrate to 2.5 mg twice daily; maintenance 2.5-15 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: 12-14 hours (biphasic, initial half-life 6-8 hours); clinical context: steady-state achieved in 2-3 days.
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).
Renal: approximately 60% as metabolites, 6% as unchanged drug; biliary/fecal: approximately 40% as metabolites and unchanged drug.
