mechanism:
None (1) ·
Partial agonist at D2 and 5HT1A. Antagonist at 5HT2A, α1A, α1B, α2C. More potent 5HT2A antagonism, 5HT1A partial agonism, and α1 antagonism (relative to D2 partial agonism) than aripiprazole, proposed to reduce akathisia and enhance affective/cognitive effects. (1) ·
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)
uses:
Schizophrenia (FDA-approved 2015). Adjunctive treatment of major depressive disorder (2015). '''Agitation associated with dementia due to Alzheimer disease''' (FDA-approved May 2023, first agent specifically approved for this problem). Investigational for PTSD (combined with sertraline). (1) ·
