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) · '"`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.

(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) · '"`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).
