'"`UNIQ--vote-00000117-QINU`"' Compared with omeprazole, pantoprazole has a more linear pharmacokinetic profile and is metabolized predominantly via CYP2C19 with CYP3A4 contribution; less CYP2C19-driven drug interaction with clopidogrel than omeprazole'"`UNIQ--ref-00000118-QINU`"'. (1) ·
'"`UNIQ--vote-00000584-QINU`"' Binds the same insulin receptor as endogenous insulin with comparable mitogenic-to-metabolic ratio. Ultra-rapid formulations (Lyumjev) add treprostinil and citrate to accelerate absorption further'"`UNIQ--ref-00000585-QINU`"'. (1) ·
'"`UNIQ--vote-000008E1-QINU`"' Like omeprazole, it is an acid-activated prodrug that covalently and irreversibly binds the H+/K+ ATPase. CYP2C19 PGx remains clinically relevant for both'"`UNIQ--ref-000008E2-QINU`"'. (1) ·
'"`UNIQ--vote-00001580-QINU`"' First FDA-approved treatment for PBA. The 10 mg quinidine daily dose is far below antiarrhythmic levels but sufficient to nearly fully inhibit CYP2D6, the basis of the combination's pharmacokinetic rationale'"`UNIQ--ref-00001581-QINU`"'. (1)
