Apomorphine (Apokyn Ixense Spontane Uprima) is a non-selective dopamine agonist which activates both D1-like and D2-like receptors with some preference for the latter subtypes. It is historically a morphine decomposition product by boiling with concentrated acid hence the -morphine suffix. Apomorphine does not actually contain morphine or its skeleton nor does it bind to opioid receptors.
