Interaction Effect
Increased daridorexant and CYP3A4 substrate with NTI exposure
Interaction Summary
Concomitant use of daridorexant (CYP3A4 substrate) with a moderate CYP3A4 inhibitor which is also a CYP3A4 substrate with NTI as it increases exposure to daridorexant and CYP3A4 substrate with NTI, which may increase the risk of adverse reactions. If used concomitantly, use caution and do not exceed daridorexant dose of 25 mg once per night[1].

How To Manage Interaction
Concomitant use of daridorexant (CYP3A4 substrate) with a moderate CYP3A4 inhibitor which is also a CYP3A4 substrate with NTI as it increases exposure to daridorexant and CYP3A4 substrate with NTI, which may increase the risk of adverse reactions. If used concomitantly, use caution and do not exceed daridorexant dose of 25 mg once per night[1].
Mechanism Of Interaction
Inhibition of CYP3A4-mediated metabolism of daridorexant; inhibition of CYP3A4-substrate metabolism by daridorexant
Literature Reports
A) Concomitant use of daridorexant 25 mg and dilTIAZem (moderate CYP3A4 inhibitor) 240 mg increased daridorexant AUC by a geometric mean ratio (GMR) of 2.4 (90% CI, 2 to 2.8) and Cmax by a GMR of 1.4 (90% CI, 1.2 to 1.6) [1].
B) Concomitant use of single dose daridorexant 50 mg and midazolam (CYP3A4 substrate) 2 mg increased daridorexant AUC by a geometric mean ratio (GMR) of 1.4 (90% CI, 1.3 to 1.6) and Cmax by a GMR of 1.1 (90% CI, 1.0 to 1.3) [1].

Crizotinib Overview
-
Crizotinib is used to treat certain types of non-small cell lung cancer (NSCLC) that has spread to nearby tissues or to other parts of the body. It is also used to treat a certain type of anaplastic large cell lymphoma (ALCL) that has returned or is unresponsive to other treatment(s) in certain adults and children 1 year of age and older. Crizotinib is also used to treat a certain type of inflammatory myofibroblastic tumor (IMT; type of cancer that occurs in mucosal tissues usually in the abdominal area, involving the lungs, bladder, stomach, uterus, liver, or intestines) that cannot be treated with surgery or that has not improved or has come back after previous treatment(s) in adults and children 1 year of age and older. Crizotinib is in a class of medications called kinase inhibitors. It works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply.
Daridorexant Overview
-
Daridorexant is used to treat insomnia (difficulty falling asleep or staying asleep). Daridorexant is in a class of medications called orexin receptor antagonists. It works by blocking the action of a certain natural substance in the brain that causes wakefulness.
