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-00000016-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-00000017-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) ·
'"`UNIQ--vote-0000104D-QINU`"' Adequate hydration is at least as important as the drug in producing the expectorant effect clinically. Used in combination with dextromethorphan, decongestants, or antihistamines in many proprietary OTC cold preparations. (1)
