Flupentixol/melitracen (trade name Frenxit, Franxit, Placida, Deanxit, Anxidreg, Danxipress, Mocalm) is a combination of two psychoactive agents flupentixol and melitracen. It is designed for short term usage only. It is produced by Lundbeck.[1]
Flupentixol is a thiazolyl (thioanthracene) antipsychotic, and melitracen is a tricyclic antidepressant. Low dose Flupentixol (0.5mg-3mg) has antidepressant and anti-anxiety effects, while melitracen has antidepressant effect. The mixture of the two components is used to treat mild to moderate mental disorders.
Flupentixol acts as a dopamine 1 and 2 receptor antagonist and melitracen acts in similar way to other tricyclic antidepressants blocking the reuptake of serotonin and norepinephrine in presynaptic terminals.
