Mechanism of Action
Trifluoperazine inhibits dopamine D2 receptors in the brain. It has weak anticholinergic and sedative effects but strong extrapyramidal and antiemetic effects. It controls severely disturbed, agitated or violent behaviour but may also be used for nonpsychotic anxiety.
Trihexyphenidyl/Benzhexol is added to treat and prevent these side effects. Trihexyphenidyl HCl is a tertiary amine antimuscarinic which exerts a direct inhibitory effect on the parasympathetic nervous system. It also exhibits a direct spasmolytic action on smooth muscle, weak mydriatic, antisialagogue and cardiovagal blocking effects.
