Action of Zyprexa:
Zyprexa belongs to a group of drugs called antipsychotics. It works by blocking various receptors in the brain, particularly dopamine receptors. Dopamine is a natural compound involved in transmitting signals between brain cells. Psychotic illness is considered to be caused by overactivity of dopamine in the brain. Zyprexa blocks the receptors that dopamine acts on and this helps to control psychotic illness.
