Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Apomorphine is a non-ergoline dopamine receptor agonist with high affinity for D4 and moderate affinity for D2, D3, D5, and D1 receptors. It also has affinity for serotonergic (5-HT1A, 5-HT2A, 5-HT2B) and adrenergic (α1, α2) receptors. It improves motor function in Parkinson disease by stimulating striatal dopamine receptors.
Non-ergoline dopamine agonist that selectively binds to D2 and D3 dopamine receptors, particularly D3, in the striatum and substantia nigra, mimicking dopamine's effects to improve motor function in Parkinson's disease.
Sublingual film: 10 mg, 15 mg, 20 mg, 25 mg, or 30 mg as a single dose for acute off episodes; may repeat once within 4 hours if inadequate response; maximum 30 mg per dose and 3 doses per day.
0.125 mg orally three times daily, titrated as tolerated to maximum 4.5 mg/day

The terminal elimination half-life of apomorphine is approximately 40 minutes. This short half-life necessitates continuous administration via subcutaneous infusion for sustained clinical effect.
Terminal half-life: 8–12 hours in young adults; up to 15–18 hours in elderly. Clinical context: Once-daily dosing; steady-state in 2–4 days.
Apomorphine is predominantly metabolized in the liver. Renal excretion accounts for approximately 80% of the dose, with 10% excreted as unchanged drug and 70% as metabolites. Biliary/fecal excretion accounts for the remaining 20%.
Renal: ~90% unchanged in urine; biliary/fecal: ~2%.
