Mechanism of Action: Flupenthixol dihydrochloride is a typical antipsychotic drug belonging to the thioxanthene class. It exhibits its effects primarily by antagonizing dopamine D2 receptors in the brain, which helps to reduce psychotic symptoms such as hallucinations and delusions. In addition to this, it can also block other neurotransmitter receptors, including serotonin receptors, contributing further to its antipsychotic activity.
