mechanism:
5-HT1A agonist, 5-HT2A antagonist, with weaker activity at D4 and other receptors. Net effect involves enhanced prefrontal dopaminergic/noradrenergic tone with decreased serotonergic inhibition of sexual desire. (1) ·
Endogenous androgen binding to androgen receptors; mediates male secondary sex characteristics, anabolism, libido, erythropoiesis, and CNS effects on mood/energy/aggression. Aromatized peripherally to estradiol; reduced to DHT. (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-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-000000B6-QINU`"' Active metabolite EXP3174 is ~10-40-fold more potent than the parent and accounts for most of the antihypertensive effect; CYP2C9 polymorphism affects conversion'"`UNIQ--ref-000000B7-QINU`"'. (1) ·
'"`UNIQ--vote-00000762-QINU`"' Largely renally cleared, hence the eGFR-tiered dosing. Rare but well-documented signals: acute pancreatitis (uncertain causal contribution), severe joint pain, and bullous pemphigoid (class effect, especially in older Asian patients)'"`UNIQ--ref-00000763-QINU`"'. (1)
