The combination of Flupentixol and Melitracen does not seem to influence the pharmacokinetic properties of the individual compounds.
Flupenthixol primarily acts as a neuroleptic drug. The antipsychotic effect of Flupenthixol is achieved by mixed blockade of dopamine D1 and D2 receptors. In the mesolimbic dopamine system of the brain, this accounts for the antipsychotic action of this drug. Flupenthixol has other effects on CNS. In the chemoreceptor trigger zone, the dopamine blockade accounts for the antiemetic effect of the drug.
Melitracen is a tricyclic antidepressant. It blocks the neuronal re-uptake of both serotonin and nor-epinephrine in the central nervous system, there by minimizing the symptoms of depression.
