What happens
Increased ubrogepant exposure
Interaction Deep Dive
Concomitant use of ubrogepant with a BCRP transport inhibitor may increase ubrogepant exposure. If used concomitantly in patients with hepatic or renal impairment, the initial ubrogepant dose should be 50 mg and a second 50-mg dose may be administered at least 2 hours after the initial dose if necessary1.
Why it happens (mechanism)
Inhibition of BCRP efflux transport of ubrogepant
