mechanism:
None (2) ·
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) ·
'"`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-000005D0-QINU`"' Selectivity comes from the viral-kinase-only initial phosphorylation step, which is why uninfected cells generate minimal active drug'"`UNIQ--ref-000005D1-QINU`"'. Dose-adjust by renal function; rare crystalline nephropathy with rapid IV acyclovir. (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)
