Introduction

β-adrenergic blocking agent.1 2 3 4 5 6 7 8 9 10 11 20 24


Uses for Nebivolol Hydrochloride


Hypertension


Management of hypertension (alone or in combination with other classes of antihypertensive agents).1 2 3 4 5 6 10 11 24


One of several preferred initial therapies in hypertensive patients with heart failure, postmyocardial infarction, high CHD risk, and/or diabetes mellitus.12


Can be used as monotherapy for initial management of uncomplicated hypertension; however, thiazide diuretics are preferred by JNC 7.12


Nebivolol Hydrochloride Dosage and Administration


General



  • Individualize dosage according to patient response.1




  • If long-term therapy is discontinued, reduce dosage gradually over a period of about 1–2 weeks.1 (See Abrupt Withdrawal of Therapy under Cautions.)




  • β1-Adrenergic blocking selectivity diminishes as dosage is increased beyond 10 mg.1



Administration


Oral Administration


Administer orally once daily without regard to meals.1


Frequent administration (i.e., daily divided doses) unlikely to be more beneficial than once-daily administration.1


Dosage


Available as nebivolol hydrochloride; dosage expressed in terms of nebivolol.1


Adults


Hypertension

Oral

Initially, 5 mg once daily.1 11 24 Increase at 2-week intervals (up to 40 mg daily) in patients whose BP is uncontrolled with the initial dosage.1 11


Prescribing Limits


Adults


Hypertension

Oral

Maximum 40 mg daily.1


Special Populations


Hepatic Impairment


Initially, 2.5 mg once daily in patients with moderate hepatic impairment (Child-Pugh class B).1 11 Increase dosage carefully, if necessary.1


Contraindicated in patients with severe hepatic impairment (Child-Pugh class C).1 6 (See Contraindications under Cautions.)


Renal Impairment


Initially, 2.5 mg once daily in patients with severe renal impairment (Clcr <30 mL/minute).1 11 Increase dosage carefully, if necessary.1


Geriatric Patients


Dosage adjustment not required.1


CYP2D6 Metabolizers


No dosage adjustment required in poor metabolizers of CYP2D6 substrates.1 7


Cautions for Nebivolol Hydrochloride


Contraindications



  • Severe bradycardia.1




  • Heart block greater than first degree.1




  • Cardiogenic shock.1




  • Decompensated cardiac failure.1 (See Cardiac Failure under Cautions.)

Warnings/Precautions


Warnings


Abrupt Withdrawal of Therapy

Abrupt discontinuance of therapy is not recommended as it may exacerbate angina symptoms or precipitate MI and ventricular arrhythmias in patients with CAD.1 Gradually decrease dosage over a period of about 1–2 weeks; monitor patients carefully and advise patients to temporarily limit their physical activity during withdrawal of therapy.1 If exacerbation of angina occurs or acute coronary insufficiency develops, reinstitute therapy (at least temporarily).1


Cardiac Failure

Possible precipitation of CHF.1


Avoid use in patients with overt CHF; use cautiously in patients with inadequate cardiac function and, if necessary, in patients with well-compensated heart failure.1 If heart failure worsens, consider discontinuing therapy.1


Ischemic Heart Disease

Safety and efficacy in patients with angina pectoris or recent MI have not been established.1


Major Surgery

Possible increased risks associated with general anesthesia (e.g., severe hypotension, difficulty in restarting or maintaining a heart beat) have occurred in some patients who received β-adrenergic blocking agents.1 Use with caution in patients undergoing major surgery involving general anesthesia, especially with myocardial-depressant anesthetics (e.g., cyclopropane, ether, trichloroethylene).1


Effects of β-adrenergic blocking agents can be reversed by administration of β-agonists (e.g., dobutamine, isoproterenol).1


Bronchospastic Disease

Possible bronchospasm.1 Generally should not be used in patients with bronchospastic disease.1 2


Diabetes Mellitus and Hypoglycemia

Possible decreased signs and symptoms of hypoglycemia (e.g., tachycardia) and increased insulin-induced hypoglycemia.1


Use with caution in patients with history of spontaneous hypoglycemia and in patients with diabetes receiving hypoglycemic agents.1


Thyrotoxicosis

Signs of hyperthyroidism (e.g., tachycardia) may be masked.1 Possible exacerbation of hyperthyroidism or thyroid storm if therapy is abruptly withdrawn.1


Peripheral Vascular Disease

Possible precipitation or aggravation of arterial insufficiency.1 Use with caution.1


Interactions

Concomitant use with nondihydropyridine calcium-channel blocking agents (e.g. verapamil, diltiazem) requires caution.1 (See Specific Drugs under Interactions.)


General Precautions


Risk of Anaphylactic Reactions

Patients with a history of anaphylactic reactions to a variety of allergens may be more reactive to repeated accidental, diagnostic, or therapeutic challenges with allergens while taking β-adrenergic blocking agents.1 Such patients may be unresponsive to usual doses of epinephrine.1


Pheochromocytoma

Use with caution in patients suspected of having pheochromocytoma; initiate therapy with α-adrenergic blocking agent before using any β-adrenergic blocking agent.1


Specific Populations


Pregnancy

Category C.1


Lactation

Distributed into milk in rats; not known whether distributed into human milk.1 Discontinue nursing or drug.1


Pediatric Use

Safety and efficacy not established in children <18 years of age.1


Geriatric Use

Extent


Distributed into milk in rats; not known whether distributed into human milk.1


Plasma Protein Binding


Approximately 98% (mainly albumin).1


Elimination


Metabolism


Undergoes first-pass metabolism in the liver mainly via glucuronidation of the parent drug and, to a lesser extent, via N-dealkylation and oxidation by CYP2D6.1 2 7 11


Elimination Route


Excreted in urine (38%) and feces (44%), principally as metabolites;1 <0.5% eliminated in urine and feces as unchanged drug.7 11


Half-life


12 hours for d-nebivolol.1


Special Populations


Poor CYP2D6 metabolizers: Eliminated in urine (67%) and feces (13%), principally as metabolites.1 7 Half-life is 19 hours.1


Decreased clearance in patients with moderate hepatic impairment (Child-Pugh class B) or with severe renal impairment (Clcr <30 mL/minute).1 7


Stability


Storage


Oral


Tablets

Tight, light-resistant containers at 20–25° C.1


ActionsActions



  • Inhibits response to adrenergic stimuli by competitively blocking β1-adrenergic receptors within the myocardium in extensive CYP2D6 metabolizers and at doses ≤10 mg.1 Blocks both β1- and β2-adrenergic receptors in poor CYP2D6 metabolizers and at doses >10 mg.1




  • Exhibits vasodilatory effects through stimulation of endothelial nitric oxide activity;2 7 8 9 10 24 precise mechanism of this effect not fully elucidated.7 9




  • Precise mechanism of hypotensive action not fully elucidated;1 may reduce BP by decreasing heart rate, myocardial contractility, and sympathetic outflow from the CNS; suppressing renin activity; and/or decreasing peripheral vascular resistance as a result of its vasodilating effects.1 11




  • Does not exhibit intrinsic sympathomimetic (β1-agonist) activity, membrane-stabilizing (local anesthetic) activity, or α1-adrenergic blocking activity at clinically relevant concentrations.1 7




  • Racemic mixture: d-isomer has substantial β-adrenergic blocking activity; l-isomer appears to be pharmacologically active, but precise contribution to pharmacologic effects not fully established.2 7



Advice to Patients



  • Importance of taking nebivolol exactly as prescribed.1




  • Importance of not interrupting or discontinuing therapy without consulting a clinician;1 patients should temporarily limit physical activity when discontinuing therapy.1




  • If a dose is missed, importance of patient taking only the next scheduled dose (i.e., the next dose should not be doubled).1




  • Importance of avoiding some activities (e.g., driving, operating machinery) until effects on the patient are known.1




  • Importance of warning patients receiving insulin or oral hypoglycemic agents and those subject to spontaneous hypoglycemia that β-adrenergic blocking agents can mask some symptoms of hypoglycemia (e.g., tachycardia).1




  • Importance of immediately informing clinician at the first sign or symptom (e.g., weight gain, shortness of breath) of CHF.1




  • Importance of patients informing their anesthesiologist or dentist about nebivolol therapy before undergoing major surgery.1




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.1




  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1




  • Importance of informing patients of other important precautionary information.1 (See Cautions.)
