Pharmacology

Nebivolol: Highly-selective inhibitor of beta1-adrenergic receptors; at doses ≤10 mg nebivolol preferentially blocks beta1-receptors. Nebivolol, unlike other beta-blockers, also produces an endothelium-derived nitric oxide-dependent vasodilation resulting in a reduction of systemic vascular resistance.

Valsartan: Produces direct antagonism of the angiotensin II (AT2) receptors, unlike the ACE inhibitors. It displaces angiotensin II from the AT1 receptor and produces its blood pressure-lowering effects by antagonizing AT1-induced vasoconstriction, aldosterone release, catecholamine release, arginine vasopressin release, water intake, and hypertrophic responses. This action results in more efficient blockade of the cardiovascular effects of angiotensin II and fewer side effects than the ACE inhibitors.

Use: Labeled Indications

Drug Interactions

ACE Inhibitors: Angiotensin II Receptor Blockers may enhance the adverse/toxic effect of ACE Inhibitors. Angiotensin II Receptor Blockers may increase the serum concentration of ACE Inhibitors. Management: In US labeling, use of telmisartan and ramipril is not recommended. It is not clear if any other combination of an ACE inhibitor and an ARB would be any safer. Consider alternatives to the combination when possible. Consider therapy modification

Adverse Reactions

See individual agents for reactions.

ALERT: U.S. Boxed Warning

Fetal toxicity:

When pregnancy is detected, discontinue nebivolol/valsartan as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.

Warnings/Precautions

Concerns related to adverse effects:

• Anaphylactic reactions: Use nebivolol with caution with history of severe anaphylaxis to a variety of allergens; patients taking beta-blockers may become more sensitive to repeated challenges. Treatment of anaphylaxis (eg, epinephrine) in patients taking beta-blockers may be ineffective or promote undesirable effects.

• Angioedema: Angioedema has been reported rarely with some angiotensin II receptor antagonists (ARBs) and may occur at any time during treatment (especially following first dose). It may involve the head and neck (potentially compromising airway) or the intestine (presenting with abdominal pain). Patients with idiopathic or hereditary angioedema or previous angioedema associated with ACE-inhibitor therapy may be at an increased risk. Prolonged frequent monitoring may be required, especially if tongue, glottis, or larynx are involved, as they are associated with airway obstruction. Patients with a history of airway surgery may have a higher risk of airway obstruction. Discontinue therapy immediately if angioedema occurs. Aggressive early management is critical. Intramuscular (IM) administration of epinephrine may be necessary. Do not readminister to patients who have had angioedema with ARBs.

• Hyperkalemia: May occur with valsartan; risk factors include renal impairment, diabetes mellitus, concomitant use of potassium-sparing diuretics, potassium supplements, and/or potassium-containing salts. Use with caution with these agents; monitor potassium closely.

• Hypotension: Symptomatic hypotension may occur upon initiation of valsartan in patients who are salt- or volume-depleted (eg, those treated with high-dose diuretics); correct volume depletion prior to administration. This transient hypotensive response is not a contraindication to further treatment.

• Renal function deterioration: Valsartan may be associated with deterioration of renal function and/or increases in serum creatinine, particularly in patients with low renal blood flow (eg, renal artery stenosis, heart failure) whose glomerular filtration rate (GFR) is dependent on efferent arteriolar vasoconstriction by angiotensin II; deterioration may result in oliguria, acute renal failure, and progressive azotemia. Small increases in serum creatinine may occur following initiation; consider discontinuation only in patients with progressive and/or significant deterioration in renal function.

Disease-related concerns:

• Aortic/mitral stenosis: Use valsartan with caution in patients with significant aortic/mitral stenosis.

• Bronchospastic disease: In general, patients with bronchospastic disease should not receive beta-blockers.

• Diabetes: Use with caution in patients with diabetes mellitus; nebivolol may potentiate hypoglycemia and/or mask signs and symptoms.

• Heart failure: Use with caution in patients with heart failure and monitor for a worsening of the condition. Patients should be stabilized on heart failure regimen prior to initiation of a beta-blocker.

• Hepatic impairment: Not recommended as initial treatment in patients with moderate hepatic impairment (recommended starting dose of nebivolol in these patients is not available in this combination product). Contraindicated in patients with severe hepatic impairment.

• Myasthenia gravis: Use nebivolol with caution in patients with myasthenia gravis.

• Peripheral vascular disease (PVD) and Raynaud disease: Nebivolol may precipitate or aggravate symptoms of arterial insufficiency in patients with PVD and Raynaud disease. Use with caution and monitor for progression of arterial obstruction.

• Pheochromocytoma (untreated): Adequate alpha-blockade is required prior to use of any beta-blocker.

• Psoriasis: Beta-blocker use has been associated with induction or exacerbation of psoriasis, but cause and effect have not been firmly established.

• Psychiatric disease: Use beta blockers with caution in patients with a history of psychiatric illness; may cause or exacerbate CNS depression.

• Renal artery stenosis: Use valsartan with caution in patients with unstented unilateral/bilateral renal artery stenosis. When unstented bilateral renal artery stenosis is present, use is generally avoided due to the elevated risk of deterioration in renal function unless possible benefits outweigh risks.

• Renal impairment: Not recommended as initial treatment in patients with severe impairment (recommended starting dose of nebivolol in these patients is not available in this combination product).

• Thyroid disease: Nebivolol may mask signs of hyperthyroidism (eg, tachycardia). If thyrotoxicosis is suspected, carefully manage and monitor; abrupt withdrawal may exacerbate symptoms of hyperthyroidism or precipitate thyroid storm.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Pregnancy: [US Boxed Warning]: Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.

• Surgical patients: In patients on chronic angiotensin receptor blocker (ARB) therapy, intraoperative hypotension may occur with induction and maintenance of general anesthesia; however, discontinuation of therapy prior to surgery is controversial. If continued preoperatively, avoidance of hypotensive agents during surgery is prudent (Hillis 2011). Chronic beta-blocker therapy should not be routinely withdrawn prior to major surgery.

Other warnings/precautions:

• Abrupt withdrawal: Beta-blocker therapy should not be withdrawn abruptly (particularly in patients with coronary artery disease), but gradually tapered over 1 to 2 weeks to avoid acute tachycardia, hypertension, and/or ischemia. Severe exacerbation of angina, ventricular arrhythmias, and myocardial infarction (MI) have been reported following abrupt withdrawal of beta-blocker therapy. Temporary but prompt resumption of beta-blocker therapy may be indicated with worsening of angina or acute coronary insufficiency.

Monitoring Parameters

Blood pressure; renal function; baseline and periodic electrolyte panels; serum glucose (in diabetic patients).

Pregnancy Considerations

[US Boxed Warning]: Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected. Refer to individual monographs.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weak, shortness of breath, numbness or tingling feeling), signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, a tachycardia, confusion, increased hunger, or sweating), shortness of breath, excessive weight gain, swelling in the arms or legs, dizziness, passing out, bradycardia, abnormal heartbeat, or abdominal pain (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

Intended Use and Disclaimer: Should not be printed and given to patients. This information is intended to serve as a concise initial reference for health care professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience, and judgment in diagnosing, treating, and advising patients.
