Byvalson – Comprehensive Product Description | EZ Chemist Online Pharmacy
Overview
Byvalson is a prescription antihypertensive combination medication containing Nebivolol (a beta-1 adrenergic blocker) and Valsartan (an angiotensin II receptor blocker – ARB). It is clinically proven to lower blood pressure by combining two complementary mechanisms—reducing heart rate and blocking vasoconstriction—thereby reducing cardiovascular risk.

Byvalson (Nebivolol + Valsartan) is a prescription combination antihypertensive that lowers blood pressure by reducing heart rate and blocking angiotensin II–mediated vasoconstriction. Used once daily, it is clinically proven to manage hypertension and reduce cardiovascular risk. Not suitable for pregnancy or in patients with severe heart block. Common side effects include headache, fatigue, and dizziness.
Active Ingredients
Nebivolol Hydrochloride – 5 mg (Beta-1 Selective Adrenergic Blocker)

Valsartan – 80 mg (Angiotensin II Receptor Blocker – ARB)

Other Popular and Common Names
Nebivolol + Valsartan Tablets

Byvalson 5/80

Beta-blocker + ARB combination for hypertension

Mode of Action
Byvalson works through dual antihypertensive mechanisms:

Nebivolol: Selectively blocks beta-1 adrenergic receptors in the heart, reducing heart rate, myocardial contractility, and cardiac output. It also enhances nitric oxide release, promoting vasodilation.

Valsartan: Blocks angiotensin II type 1 (AT1) receptors, preventing vasoconstriction and aldosterone release, thereby reducing vascular resistance and sodium retention.

Clinical trials show additive blood pressure-lowering effects when combining these agents versus monotherapy.

Uses / Indications
Primary Use: Management of essential hypertension in adults.

Secondary Cardiovascular Benefits: Reduces risk of stroke, heart attack, and cardiovascular complications associated with high blood pressure.

Dosage & Administration
Typical Adult Dose:

Initial dose: 5 mg Nebivolol / 80 mg Valsartan orally once daily.

Dose may be adjusted based on clinical response and tolerability.

Can be taken with or without food.

Missed Dose: Take as soon as remembered unless it’s near the time for the next dose. Do not double dose.

Prescribing Information & Safety Guidelines
Not recommended in severe hepatic impairment.

Caution in patients with renal dysfunction, heart block, or history of bradycardia.

Gradual withdrawal is advised to avoid rebound hypertension or cardiac events.

Monitor blood pressure, heart rate, and renal function regularly.

Side Effects
Common:

Headache

Fatigue

Dizziness

Nausea

Less Common but Serious:

Hypotension

Bradycardia

Hyperkalemia

Renal impairment

Seek medical attention if you experience chest pain, difficulty breathing, or swelling of the face/lips.

Warnings & Cautions
Avoid in pregnancy – may cause fetal toxicity.

Contraindicated in severe bradycardia, AV block >1st degree, cardiogenic shock.

May mask symptoms of hypoglycemia in diabetic patients.

Avoid potassium supplements or salt substitutes unless prescribed.

Drug Classification
Therapeutic Class: Antihypertensive Combination

Pharmacologic Class: Beta-1 Adrenergic Blocker + Angiotensin II Receptor Blocker (ARB)

Drug Interactions (Clinical Evidence)
Other antihypertensives – additive BP-lowering effect.

NSAIDs – may reduce antihypertensive efficacy and impair renal function.

Potassium-sparing diuretics / supplements – increased risk of hyperkalemia.

Rifampin – may reduce valsartan plasma levels.
