In plaque psoriasis studies, the safety of Taltz in combination with other immunomodulatory agents or phototherapy has not been evaluated.
In population pharmacokinetic analyses, clearance of ixekizumab was not affected by concomitant administration of oral corticosteroids, NSAIDs, sulfasalazine, or methotrexate.
Cytochrome P450 substrates: Results from an interaction study in patients with moderate-to-severe psoriasis determined that 12 weeks of administration of ixekizumab with substances metabolised by CYP3A4 (i.e., midazolam), CYP2C9 (i.e., warfarin), CYP2C19 (i.e., omeprazole), CYP1A2 (i.e., caffeine) or CYP2D6 (i.e., dextromethorphan) does not have a clinically significant impact on the pharmacokinetics of these substances.
