التداخل بين ريتونافير وفيلازودون

CYP3A4 Inhibitors: The VIIBRYD dose should not exceed 20 mg once daily when co-administered with strong CYP3A4 inhibitors ( 2.4 , 7 ).

CYP3A4 Inducers: Consider increasing VIIBRYD dosage by 2-fold, up to 80 mg once-daily over 1 to 2 weeks when used concomitantly with strong CYP3A4 inducers for greater than 14 days ( 2.4 , 7 ).

Strong CYP3A4 Inhibitors (e.g., itraconazole, clarithromycin, voriconazole) The concomitant use of VIIBRYD and strong CYP3A4 inhibitors increased the exposure of vilazodone compared to the use of VIIBRYD alone [see Clinical Pharmacology ( 12.3 )].

The VIIBRYD dose should not exceed 20 mg once daily with the concomitant use of a strong CYP3A4 inhibitor [see Dosage and Administration ( 2.4 ) , Clinical Pharmacology ( 12.3 ) ] .

Strong CYP3A4 Inducers (e.g., carbamazepine, phenytoin, rifampin) The concomitant use of VIIBRYD and strong CYP3A4 inducers decreased the exposure of vilazodone compared to the use of VIIBRYD alone [see Clinical Pharmacology ( 12.3 )].

Antidepressants: nefazodone, selective serotonin reuptake inhibitors (SSRIs): e.g. fluoxetine, paroxetine, tricyclics: e.g. amitriptyline, nortriptyline ↑ antidepressants A dose decrease may be needed for these drugs when co-administered with ritonavir.

Antidepressant: bupropion ↓ bupropion ↓ active metabolite, hydroxybupropion Patients receiving ritonavir and bupropion concurrently should be monitored for an adequate clinical response to bupropion.

Antidepressant: desipramine ↑ desipramine Dosage reduction and concentration monitoring of desipramine is recommended.

Antidepressant: trazodone ↑ trazodone Adverse events of nausea, dizziness, hypotension and syncope have been observed following co-administration of trazodone and NORVIR.
