BBC NEWS | Health | Drug 'treats depression in hours'

BBC NEWS | Health | Drug 'treats depression in hours':
"Many antidepressants target levels of brain chemicals, such as serotonin and dopamine, and, over time, the accumulation of these chemicals can affect a patient's mood. But this can take several weeks.

But the team believes ketamine is having a faster effect because it is targeting a different brain-protein, called the NMDA receptor, which is thought to play a critical role in learning and memory.

The team says ketamine, in its current form, would not be appropriate for medication because of side-effects at higher doses, which include hallucinations and euphoria."

and yet my vet friend refuses to give me any.
