Legend
              Potential elevated exposure of the antidepressant      
              Potential decreased exposure of the antidepressant
            No significant effect
D              Potential decreased exposure of ARV drug
E              Potential elevated exposure of ARV drug
ATV/c     ATV co-formulated with COBI (300/150 mg qd)
DRV/c     DRV co-formulated with COBI (800/150 mg qd)

Numbers refer to increased or decreased AUC as observed in drug-drug interaction studies

SSRI  =  selective serotonin reuptake inhibitors
SNRI  =  serotonin and norepinephrine reuptake inhibitors
TCA   =  tricyclic antidepressants
TeCA =  tetracyclic antidepressants

No clinically relevant interactions expected with ZDV and antidepressants

 

Comments

  1. ECG monitoring is recommended      
  2. Caution as both drugs can induce QT interval prolongation
  3. No PK change with unboosted ATV
  4. The European SmPC recommends DTG 50 mg bid in persons without INSTI resistance. The US Prescribing Information recommends that co-administration should be avoided as there are insufficient data to make dosing recommendations
