'"`UNIQ--vote-000001F6-QINU`"' CYP3A4 (primary) and P-glycoprotein substrate; strong dual inhibitors or inducers materially shift exposure. Reversal: andexanet alfa for life-threatening bleeding; 4F-PCC commonly used off-label when andexanet unavailable'"`UNIQ--ref-000001F7-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)
