None (1) · '"`UNIQ--vote-00000013-QINU`"' Strong CYP3A4 induction via the phenobarbital metabolite produces many interactions (reduces oral contraceptives, warfarin, many psychotropics). Essential-tremor efficacy is the unique pharmacological selling point'"`UNIQ--ref-00000014-QINU`"'. (1) · '"`UNIQ--vote-00000762-QINU`"' Largely renally cleared, hence the eGFR-tiered dosing.
