Highly β1-selective adrenergic antagonist. Greater selectivity than metoprolol or atenolol. (1) · Norepinephrine–dopamine reuptake inhibition (DAT, NET), d-threo enantiomer of methylphenidate (1) · Selective inhibitor of phosphodiesterase type 5 (PDE5), preventing cGMP breakdown in vascular smooth muscle. In the corpus cavernosum, potentiates the NO/cGMP cascade triggered by sexual stimulation. (1) · The d-enantiomer is a highly β1-selective antagonist; the l-enantiomer triggers endothelial nitric-oxide–mediated vasodilation. Unique among beta blockers for this NO mechanism. (1) · '"`UNIQ--vote-00000255-QINU`"' Less potent and shorter-acting than PPIs but with faster on-effect; suitable for on-demand acid suppression. Largely renally cleared; dose-adjust in renal impairment to avoid CNS effects (confusion in elderly)'"`UNIQ--ref-00000256-QINU`"'. (1)
