Nebivolol Macleods Pharma Uk (Nebivolol)

Nebivolol is a selective β1‑adrenergic antagonist used in cardiovascular therapy. It is employed for the following recognised indications:

• Hypertension: lowers systolic and diastolic blood pressure to reduce cardiovascular risk.
• Heart failure: improves left‑ventricular ejection fraction and alleviates symptoms of chronic heart failure.
• Post‑myocardial infarction (when indicated): helps prevent adverse cardiac remodeling and recurrent events.

• Nebivolol selectively blocks β1‑adrenergic receptors in cardiac tissue, decreasing heart rate and myocardial contractility, which reduces cardiac output and blood pressure. In addition, it stimulates endothelial nitric oxide synthase, enhancing nitric oxide release and causing peripheral vasodilation, further contributing to its antihypertensive effect.

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

Common Side Effects

• Headache: mild to moderate intensity.
• Dizziness or light‑headedness: especially on standing.
• Fatigue or tiredness: often transient.
• Nausea or abdominal discomfort.
• Bradycardia: resting heart rate below 60 bpm.
• Peripheral edema: mild swelling of ankles or feet.

Serious or Rare Side Effects

• Severe bradycardia or heart block requiring medical attention.
• Marked hypotension leading to syncope.
• Bronchospasm in patients with asthma or COPD.
• Allergic reactions such as rash, pruritus, or angio‑edema.
• Hepatic dysfunction: elevated liver enzymes.
• Cardiogenic shock in patients with decompensated heart failure.

Nebivolol should be used with careful clinical monitoring.

• Blood pressure monitoring: check regularly to avoid excessive hypotension.
• Heart rate monitoring: assess for bradycardia, especially in patients with conduction disorders.
• Hepatic impairment: dose adjustment may be required in moderate to severe liver disease.
• Asthma/COPD: use with caution as β‑blockade can precipitate bronchospasm.
• Abrupt discontinuation: taper gradually to prevent rebound hypertension.
• Storage: Store below 25°C: keep in the original container, protect from moisture and direct sunlight.

Nebivolol may interact with several drug classes; clinicians should review patient medication lists.

Major Interactions (Avoid)

• Other beta‑blockers: additive negative chronotropic effects.
• Strong CYP2D6 inhibitors (e.g., paroxetine, quinidine): may increase nebivolol plasma concentrations.
• Non‑dihydropyridine calcium‑channel blockers (verapamil, diltiazem): can exacerbate bradycardia and AV‑node block.

Moderate Interactions (Monitor Closely):\n- ACE inhibitors or ARBs: may enhance antihypertensive effect, requiring BP monitoring.

• Diuretics: risk of orthostatic hypotension; adjust dose as needed.
• NSAIDs: may blunt antihypertensive response.
• Digoxin: monitor for bradyarrhythmias.
• Antidiabetic agents: possible enhancement of hypoglycaemic effect.
