PENTAXOL INJ

Flupenthixol and Melitracen Injection is a combination medication with a unique mechanism of action. Flupenthixol, a thioxanthene derivative, primarily acts as a potent dopamine antagonist, blocking D1 and D2 receptors in the brain. This dopamine-blocking effect helps to alleviate psychotic symptoms and mood disturbances. Melitracen, a tricyclic antidepressant, enhances the action of serotonin and norepinephrine in the central nervous system by inhibiting their reuptake. This dual action of Flupenthixol and Melitracen contributes to its effectiveness in treating depressive symptoms and anxiety. The combination of these two mechanisms provides a synergistic effect, offering relief from a range of psychiatric symptoms.
