التداخل بين أزرق الميثيلين وتولكابون

It is theoretically possible, therefore, that the combination of Tolcapone tablets and a non-selective MAO inhibitor (e.g., phenelzine and tranylcypromine) would result in inhibition of the majority of the pathways responsible for normal catecholamine metabolism.

For this reason, patients should ordinarily not be treated concomitantly with Tolcapone tablets and a non-selective MAO inhibitor.

It is difficult to determine if Tolcapone tablets played a role in the pathogenesis of these events because these patients received several concomitant medications affecting the central nervous system such as monoaminergic (i.e., MAO-I, tricyclic and selective serotonin reuptake inhibitors) and anticholinergic agents.
