How does this medicine work?[edit | edit source]

  • The hydrochloride salt form of apomorphine, a derivative of morphine and non-ergoline dopamine agonist with high selectivity for dopamine D2, D3, D4 and D5 receptors.

  • This enhances motor function, suppresses prolactin release, and causes vasodilation and behavioral effects.
