Lipophilic metabolites, such as nortriptyline, are most likely to be reabsorbed and further metabolized. Cardiac dysrhythmias can result from the direct quinidine-like effect on cardiac function combined with anticholinergic activity and norepinephrine potentiation. The antimuscarinic activity of tricyclic antidepressants can decrease gastric motility, decreasing the bioavailability of levodopa. Conversely, tricyclic antidepressants should not be added to an exisiting MAOI regimen because the reuptake blockade will be unopposed due to the existing inhibition of the main elimination pathway.
