“…Indeed, these studies all showed that pharmacological inhibition of IL-6 restored CYP3A activity, with a significant decrease in simvastatin exposure of approximately 55 and 57% after the administration of sarilumab ( Lee, Daskalakis, et al, 2017 ) or tocilizumab ( Schmitt et al, 2011 ), respectively. Conversely, several other biotherapies targeting proinflammatory cytokines, such as TNF-ɑ ( Deng et al, 2018 ; Frye, Schneider, Frye, & Feldman, 2002 ), IL-17 ( Bruin et al, 2019 ), or IL-23 ( Khalilieh et al, 2018 ; Khatri et al, 2019 ) did not influence CYP activity. However, any effect of such biologics needs to be verified for various diseases with varying levels of proinflammatory cytokines, as the magnitude of these disease-dependent drug interactions are per se affected by the underlying disease.…”
