What happens
Decreased efficacy of tretinoin
Interaction Deep Dive
Tretinoin is metabolized in the hepatic cytochrome P450 enzyme system. Glucocorticoids induce these same enzyme pathways. Concurrent use of tretinoin and glucocorticoids may result in decreased plasma concentrations of tretinoin. However, no studies to date have shown this interaction to decrease the efficacy of tretinoin therapy1.
Why it happens (mechanism)
Induction of tretinoin metabolism
