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 binding to D2 receptors on lactotroph cells in the anterior pituitary.
Rotigotine is a non-ergoline dopamine agonist with high affinity for dopamine D1, D2, D3, D4, and D5 receptors; also binds to serotonin 5-HT1A and alpha2-adrenergic receptors.
0.25 mg orally twice weekly, with a minimum of 2 days between doses; may increase by 0.25 mg twice weekly every 4 weeks up to a maximum of 1 mg twice weekly.
Apply transdermally once daily; initial dose 2 mg/24h, titrated weekly by 2 mg/24h up to 6 mg/24h, maximum 8 mg/24h.

The terminal elimination half-life is 63–69 hours in healthy volunteers and 79–115 hours in patients with hyperprolactinemia, allowing once- or twice-weekly dosing. The long half-life reflects slow dissociation from D2 receptors and enterohepatic recirculation.
Single dose: 5-7 hours (transdermal); steady state: 7-10 hours; effective half-life for dosing is 8 hours due to reservoir in skin
Cabergoline is extensively metabolized in the liver, primarily via CYP3A4. Elimination is predominantly fecal (60%) and renal (20%) as metabolites, with <4% as unchanged drug. Biliary excretion contributes to fecal elimination.
Renal: 45% (metabolites), Fecal: 40% (metabolites), Biliary: 15%
