Apomorphine is a non-ergoline dopamine agonist used primarily in the treatment of motor fluctuations ('off' episodes) in Parkinson's disease. It is administered as a rescue medication for rapid symptom relief. It is approved for subcutaneous use and is not typically administered orally due to extensive first-pass metabolism and very low oral bioavailability.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers following subcutaneous administration.
