Synthetic T4 (thyroxine); peripherally deiodinated to T3 (triiodothyronine), the active hormone. '"`UNIQ--vote-00000031-QINU`"' Narrow therapeutic index; brand-to-generic switches can shift TSH and require re-titration'"`UNIQ--ref-00000032-QINU`"'. (1) ·
'"`UNIQ--vote-00000032-QINU`"' Brand-to-brand and lot-to-lot variability in T3:T4 ratio is greater than with synthetic levothyroxine, which is why endocrine guidelines prefer the synthetic'"`UNIQ--ref-00000033-QINU`"'. (1) ·
'"`UNIQ--vote-00000053-QINU`"' Also raises bradykinin, contributing to vasodilation and the characteristic dry cough. Renally cleared, unmetabolized; dose-adjust by eGFR'"`UNIQ--ref-00000054-QINU`"'. (1) ·
'"`UNIQ--vote-000003D1-QINU`"' SLCO1B1 polymorphism affects exposure but is most clinically actionable for simvastatin'"`UNIQ--ref-000003D2-QINU`"'. (1) ·
'"`UNIQ--vote-00000A1D-QINU`"' Like other ACE inhibitors, it raises bradykinin (driving the dry cough and rare angioedema). Renally cleared; dose-adjust in renal impairment'"`UNIQ--ref-00000A1E-QINU`"'. (1) ·
'"`UNIQ--vote-00000AEA-QINU`"' The 24-hour half-life supports once-daily dosing with consistent overnight BP control. Largely hepatically cleared (~98% biliary); no significant renal clearance dependence'"`UNIQ--ref-00000AEB-QINU`"'. (1)
