Patient summary

intended to address severe psychiatric symptoms by modulating dopaminergic pathways in the brain.

Mechanism of action

Thorazine acts primarily as an antagonist at postsynaptic dopamine receptors in the limbic system, hypothalamus, and basal ganglia. By blocking these receptors, it reduces the hyperactivity associated with psychotic conditions and helps regain stability in neurotransmitter signaling.
