Highly-selective inhibitor of beta1-adrenergic receptors
藥動學
Absorption: Rapid Distribution: Vd: 8 to 12 L/kg Protein binding: ~98%, primarily to albumin Metabolism: Hepatic(via glucuronidation and CYP2D6).Extensive first-pass metabolism to multiple active metabolites with variable activity. Bioavailability: ~12% (extensive metabolizers); 96% (poor metabolizers). Half-life elimination: Terminal: 12 hours (extensive metabolizers) or 19 hours (poor metabolizers); up to 32 hours has been reported in poor metabolizers. Time to peak, plasma: 1.5 to 4 hours Excretion: Urine (extensive metabolizers: 38%; poor metabolizers: 67%; <0.5% of total dose as unchanged drug); feces (extensive metabolizers: 44%; poor metabolizers: 13%; <0.5% of total dose as unchanged drug)
禁忌症
US labeling:Hypersensitivity to nebivolol or any component of the formulation Severe bradycardia Heart block greater than first-degree (except in patients with a functioning artificial pacemaker) Cardiogenic shock Decompensated heart failure Sick sinus syndrome (unless a permanent pacemaker is in place) Severe hepatic impairment (Child-Pugh class C) Documentation of allergenic cross-reactivity for beta-blockers is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Canadian labeling: Severe peripheral arterial circulatory disorders Sinoatrial block Rare hereditary conditions of Galactose intolerance Congenital lactase deficiency or glucose-galactose malabsorption.
懷孕分類
1.Outcome information following maternal use of nebivolol in pregnancy is limited. 2. If maternal use of a beta-blocker is needed, fetal growth should be monitored during pregnancy and the newborn should be monitored for 48 hours after delivery for bradycardia, hypoglycemia, and respiratory depression 3.仿單:not recommened
哺乳分類
1.It is not known if nebivolol is present in breast milk. 2.Breastfeeding is not recommended by the manufacturer due to the potential for beta-blockers to produce serious effects on breastfed infants, especially bradycardia.
Hypertension (alternative agent): Oral: Initial: 5 mg once daily; titrate as needed at 2-week intervals based on patient response to a maximum dose of 40 mg once daily (ACC/AHA [Whelton 2017]). Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
小兒調整劑量
仿單:not recommened
腎功能調整劑量
CrCl 50 to 80 mL/minute:There are no dosage adjustments provided in the manufacturer’s labeling; however, dose adjustment does not appear necessary. Following a single 5 mg dose in patients with CrCl 50 to 80 mL/minute, nebivolol clearance was unchanged. CrCl 30 to 50 mL/minute:There are no dosage adjustments provided in the manufacturer’s labeling; however, dose adjustment is likely not necessary. Following a single 5 mg dose in patients with moderate impairment, reduction in nebivolol clearance was negligible (~17%). CrCl <30 mL/minute:Initial: 2.5 mg once daily; if initial response is inadequate, may increase cautiously. Hemodialysis: There are no dosage adjustments provided in the manufacturer’s labeling (has not been studied).
肝功能調整劑量
Mild impairment (Child-Pugh class A): There are no dosage adjustments provided in the manufacturer’s labeling; use caution. Moderate impairment (Child-Pugh class B): Initial: 2.5 mg once daily; if initial response is inadequate, may increase cautiously. Severe impairment (Child-Pugh class C): Use is contraindicated.
