Interação entre Darunavir e Fluvoxamina

Potential Pimozide Interaction Pimozide is metabolized by the cytochrome P4503A4 isoenzyme, and it has been demonstrated that ketoconazole, a potent inhibitor of CYP3A4, blocks the metabolism of this drug, resulting in increased plasma concentrations of parent drug.

Although it has not been definitively demonstrated that fluvoxamine is a potent CYP3A4 inhibitor, it is likely to be, given the substantial interaction of fluvoxamine with alprazolam.

Fluvoxamine is a known potent inhibitor of CYP1A2 and also inhibits CYP3A4, CYP2C9, and CYP2C19.

In vitro data suggest that fluvoxamine is a relatively weak inhibitor of CYP2D6.

Antidepressants : Selective Serotonin Reuptake Inhibitors (SSRIs): paroxetine, sertraline ↓ paroxetine ↓ sertraline If either sertraline or paroxetine is initiated in patients receiving PREZISTA/ritonavir, dose titrating the SSRI based on a clinical assessment of antidepressant response is recommended.

Monitor for antidepressant response in patients on a stable dose of sertraline or paroxetine who start treatment with PREZISTA/ritonavir.

Tricyclic Antidepressants (TCAs): amitriptyline, desipramine, imipramine, nortriptyline ↑ amitriptyline ↑ desipramine ↑ imipramine ↑ nortriptyline Use a lower dose of the tricyclic antidepressants and trazodone due to potential increased adverse events such as nausea, dizziness, hypotension and syncope.
