BETAXOLOL HYDROCHLORIDE vs NEBIVOLOL HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, myocardial contractility, and blood pressure.
Selective beta-1 adrenergic receptor antagonist with nitric oxide-mediated vasodilatory activity via stimulation of beta-3 receptors.
10-20 mg orally once daily; maximum 20 mg/day.
5 mg orally once daily. May be initiated at 2.5 mg in patients with renal impairment or those at risk of hypotension. Titrate at 2-week intervals up to 40 mg once daily.

Terminal elimination half-life: 14–22 hours (mean 16 hours); sufficient for once-daily dosing in hypertension; prolonged in renal impairment.
Terminal elimination half-life: 12-19 hours in extensive metabolizers; up to 30-50 hours in poor CYP2D6 metabolizers; clinically, once-daily dosing is effective due to pharmacodynamic half-life >40 hours.
Renal: 80% (as unchanged drug and inactive metabolites), Fecal: 20%
Approximately 38% renal, 48% fecal (unchanged drug and metabolites); extensive hepatic metabolism (CYP2D6) with glucuronidation; <1% excreted unchanged in urine.
