Institute of Pharmacology, University of Messina, Italy.

The effect of fluvoxamine maleate, 100 mg/day for 10 days, on plasma concentrations of tricyclic antidepressants was studied in 15 depressed patients on maintenance therapy with imipramine (7 pts.) or desipramine (8 pts.). In the subgroup treated with imipramine, plasma levels of imipramine increased significantly (p < 0.001) during fluvoxamine coadministration, while levels of desipramine were not modified. Addition of fluvoxamine to patients on a stable desipramine dosage regimen resulted in a slight, but statistically not significant, increase in desipramine plasma concentrations. These results suggest that fluvoxamine is a potent inhibitor of imipramine demethylation, while it has a weak effect on the hydroxylation of desipramine.

D003891 Desipramine A tricyclic dibenzazepine compound that potentiates neurotransmission. Desipramine selectively blocks reuptake of norepinephrine from the neural synapse, and also appears to impair serotonin transport. This compound also possesses minor anticholinergic activity, through its affinity to muscarinic receptors.
