🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Trifluoperazine works by blocking dopamine D2 receptors in the brain, which helps reduce psychotic symptoms such as hallucinations and delusions. It also has anticholinergic and antihistaminic effects. Trihexyphenidyl is an anticholinergic agent that blocks acetylcholine receptors, helping to balance the reduced dopamine activity and thereby reducing extrapyramidal side effects like stiffness and tremors caused by trifluoperazine.
