Nebivolol and valsartan (Byvalsan) Side effects

See individual agents for reactions (Nebivolol and Valsartan).

Contraindications to Nebivolol and valsartan (Byvalsan):

  • Hypersensitivity to valsartan, nebivolol or any other component of the formulation

  • Heart block is more severe than the first-degree.
  • Cardiogenic shock
  • Heart failure that has been decompensated
  • Sinusitis (unless a permanent pacemaker has been installed)
  • Severe hepatic impairment (Child Puugh class C).
  • Patients with diabetes mellitus should use aliskiren concurrently

Warnings and precautions

  • Anaphylactic reactions

    • If you have a history of severe allergic reactions to many allergens, be careful when using nebivolol.
    • Beta-blockers can make patients more sensitive to repeated challenges.
    • Patients taking beta-blockers may have anaphylaxis (e.g., epinephrine), which can lead to ineffective treatment or undesirable side effects.
  • Angioedema

    • Angioedema is a rare side effect of some angiotensin II receptor inhibitors (ARBs). It can occur anytime during treatment, especially after the first dose.
    • It could involve the head and neck (potentially damaging airway) or possibly the intestine (presenting as abdominal pain).
    • Patients who have angioedema resulting from ACE-inhibitor therapy or idiopathic angioedema may be at greater risk.
    • Frequent monitoring over a long period may be necessary, particularly if the tongue, glottis or larynx is involved. This is because they can cause obstruction to the airways.
    • Patients who have had previous airway surgery may be at greater risk for airway obstruction.
    • Stop all therapy immediately if angioedema develops
    • It is crucial to be aggressive in early management.
    • IM administration of epinephrine might be required.
    • Patients who have angioedema caused by ARBs should not be readministered.
  • Hyperkalemia:

    • This may happen when you take valsartan.
    • Risk factors include renal impairment, potassium supplements, diabetes mellitus, concomitant use of potassium-sparing diuretics & potassium-containing salts.
    • These agents should be used with caution.
    • Pay attention to potassium.
  • Hypotension

    • Patients who have been treated with high-dose diuretics or salt-depleted may experience symptoms of hypotension.
    • Accurate volume depletion prior to administration.
    • The transient hypotensive response does not mean that you should be denied further treatment.
  • Renal function deterioration:

    • Valsartan may cause a decline in renal function and an increase in serum creatinine in patients with low renal bloodflow (eg, kidney artery stenosis or heart failure) whose GFR is dependent upon efferent arterial vasoconstriction (angiotensin II).
    • Deterioration can lead to oliguria, acute renal dysfunction, or progressive azotemia.
    • After initiation, small increases in serum creatinine might occur.
    • Patients with significant and progressive impairment of renal function should be considered for discontinuation.
  • Mitral and aortic stenosis:

    • Patients with severe aortic/mitral stenosis should not use valsartan.
  • Bronchospastic Disease:

    • Patients suffering from bronchospastic diseases should not be given beta-blockers.
  • Diabetes:

    • Patients with diabetes mellitus should be cautious.
    • Nebivolol can mask hypoglycemia symptoms and may even cause it.
  • Heart failure:

    • Patients with heart failure should be treated cautiously and monitored for signs of deterioration.
    • Patients should be stabilized on the heart-feilling regimen before initiating beta-blockers.
  • Hepatic impairment

    • Patients with moderate hepatic impairment should not be treated as an initial treatment. The recommended starting dose for these patients is not to use the combination product.
    • Patients with severe hepatic impairment are advised to avoid this medication.
  • Myasthenia gravis:

    • Patients with myasthenia gravis should be cautious when using nebivolol.
  • Raynaud and peripheral vascular disease (PVD).

    • Nebivolol may cause arterial insufficiency symptoms, which can be exacerbated in patients with Raynaud and PVD.
    • Be careful and check for arterial obstruction.
  • Untreated Pheochromocytoma

    • A good alpha-blockade must be in place before any beta-blocker can be used.
  • Psoriasis:

    • Beta-blocker may be associated with psoriasis exacerbation or induction, but cause and effect are not well established.
  • Renal artery stenosis

    • Patients with unstented unilateral/bilateral kidney artery stenosis should not be given valsartan.
    • If unstented bilateral renal arterial stenosis exists, it is best to avoid using this device.
  • Renal impairment

    • This combination product is not recommended for patients with severe impairment.
  • Thyroid disease:

    • Nebivolol (eg tachycardia) may mask signs of hyperthyroidism.
    • If thyrotoxicosis has been suspected, be sure to monitor and manage it.
    • Sudden withdrawal can exacerbate symptoms of hyperthyroidism and precipitate thyroid storm.

Exceptions: Apraclonidine.

Amifostine

Blood Pressure Lowering Agents may enhance the hypotensive effect of Amifostine. Management: When amifostine is used at chemotherapy doses, blood pressure lowering medications should be withheld for 24 hours prior to amifostine administration.

Beta-Blockers may enhance the vasoconstricting effect of Ergot Derivatives. Exceptions: Nicergoline.

Fingolimod

Beta-Blockers may enhance the bradycardic effect of Fingolimod. Management: Avoid the concomitant use of fingolimod and beta-blockers if possible.

Beta-Blockers may enhance the adverse/toxic effect of Grass Pollen Allergen Extract (5 Grass Extract). More specifically, Beta-Blockers may inhibit the ability to effectively treat severe allergic reactions to Grass Pollen Allergen Extract (5 Grass Extract) with epinephrine. Some other effects of epinephrine may be unaffected or even enhanced (e.g., vasoconstriction) during treatment with Beta-Blockers.

How to administer Nebivolol and valsartan (Byvalsan)?

P/O:

  • Administer with or without food.

Mechanism of action of Nebivolol and valsartan (Byvalsan):

Nebivolol:

  • Highly-selective inhibition of beta-adrenergic nerve receptors
  • Doses of =10 mg nebivolol block beta-1 receptors preferentially.
  • Nebivolol also causes an endothelium-derived, nitric oxide dependent vasodilation which, unlike other beta-blockers reduces systemic vascular resistance.

Valsartan:

 

  • Direct antagonism of angiotensin II receptors (AT2) is possible, but not with ACE inhibitors.
  • Angiotensin II is removed from the AT1 receptor. It is then produced. This lowers AT1-induced vasoconstriction and aldosterone, catecholamine, and arginine vasopressin releases, as well as water intake and hypertrophic reactions. This results in a more effective blockade of cardiovascular effects of angiotensin II and lower side effects that the ACE inhibitors.
