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) · Cardioselective β1-adrenergic antagonist. Selectivity is dose-dependent and partially lost at higher doses. (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) · '"`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-0000113A-QINU`"' Concomitant β-blocker or CCB is required when used for AF to prevent 1:1 atrial flutter conduction (flecainide can slow atrial rate to a level where AV conduction allows dangerous ventricular rates).
