Nebivolol Sandoz (Nebivolol)

• Nebivolol is a selective β1‑adrenergic antagonist indicated for cardiovascular conditions that benefit from beta‑blockade.
• Hypertension: lowers elevated blood pressure and reduces cardiovascular risk.
• Heart failure (NYHA class II‑III): improves symptoms and functional capacity in patients with reduced ejection fraction.
• Chronic stable heart failure: helps to manage long‑term heart failure symptoms and may reduce hospitalisation.

• Nebivolol selectively blocks β1‑adrenergic receptors in cardiac tissue, decreasing heart rate and myocardial contractility, which lowers cardiac output and blood pressure. In addition, it stimulates endothelial nitric oxide release, causing vasodilation and further contributing to its antihypertensive effect without significant β2‑receptor antagonism.

Nebivolol may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects

• Headache: mild to moderate pain in the head region.
• Dizziness: sensation of light‑headedness, especially on standing.
• Fatigue: general tiredness or lack of energy.
• Bradycardia: slower than normal heart rate.
• Nausea: feeling of queasiness or urge to vomit.
• Peripheral edema: swelling of the lower limbs.

Serious or Rare Side Effects

• Severe bradycardia: markedly low heart rate requiring medical attention.
• Symptomatic hypotension: significant drop in blood pressure causing faintness.
• Bronchospasm: narrowing of airways, particularly in asthmatic patients.
• Heart block: impaired electrical conduction in the heart.
• Allergic reactions: rash, itching, or swelling.
• Hepatic dysfunction: abnormal liver enzyme elevations.

• Before prescribing Nebivolol, clinicians should evaluate patient‑specific factors and monitor for potential risks.
• Cardiovascular assessment: check baseline heart rate and blood pressure.
• Renal impairment: adjust therapy if significant kidney dysfunction is present.
• Asthma or COPD: use with caution due to possible bronchoconstriction.
• Concomitant medications: review for interactions that may enhance bradycardia or hypotension.
• Pregnancy and lactation: safety not established; avoid unless benefits outweigh risks.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Nebivolol can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Non‑selective beta blockers: additive bradycardia and hypotension.
• Calcium channel blockers (verapamil, diltiazem): increased risk of AV block.
• Clonidine abrupt withdrawal: rebound hypertension.

Moderate Interactions (Monitor Closely)

• ACE inhibitors: may cause excessive blood pressure lowering.
• Diuretics: potential electrolyte disturbances and volume depletion.
• Antidiabetic agents: may mask hypoglycemia symptoms.
