Apomorphine is a potent emetic used in dogs (not recommended in cats) which acts pretty quickly. The little gasp of surprise before they start throwing up like crazy makes me chuckle to myself sometimes. Apomorphine is a dopamine receptor agonist and its reversal agent is Naloxone (0.01-0.04mg/kg). In humans, it has been used in acute and chronic studies of parkinsonism and other neurological disorders.
