Nebivololo E Idroclorotiazide Accord (Hydrochlorothiazide, Nebivolol)

Nebivolol/Hydrochlorothiazide is used to manage high blood pressure and related cardiovascular risk factors.

• Essential hypertension: lowers systolic and diastolic pressure to reduce cardiovascular events.
• Secondary hypertension: assists in controlling blood pressure when caused by other medical conditions.
• Hypertension with fluid retention: combines beta‑blockade and diuresis to manage both pressure and excess fluid.

• Nebivolol selectively blocks β1‑adrenergic receptors, decreasing heart rate and myocardial contractility, while also stimulating endothelial nitric‑oxide release for vasodilation. Hydrochlorothiazide inhibits Na⁺/Cl⁻ reabsorption in the distal convoluted tubule, promoting diuresis, reducing plasma volume, and further decreasing peripheral vascular resistance, together achieving blood‑pressure reduction.

Nebivolol/Hydrochlorothiazide may cause a range of adverse reactions.

Common Side Effects

• Headache: mild to moderate discomfort.
• Dizziness or light‑headedness: especially on standing.
• Fatigue: general tiredness.
• Increased urination: due to diuretic effect.
• Electrolyte imbalance: low potassium or sodium.
• Cough: occasional irritation of the airway.

Serious or Rare Side Effects

• Severe hypotension: dangerously low blood pressure.
• Bradycardia: markedly reduced heart rate.
• Acute kidney injury: sudden decline in renal function.
• Hyperglycaemia: elevated blood glucose levels.
• Allergic reactions: rash, swelling, or anaphylaxis.
• Electrolyte disturbances: severe hyponatraemia or hypokalaemia.

Before initiating therapy, consider patient‑specific factors and monitor appropriately.

• Renal impairment: assess kidney function and adjust dosage if needed.
• Hepatic disease: use with caution in patients with liver dysfunction.
• Diabetes mellitus: monitor blood glucose as thiazides may raise glucose levels.
• Electrolyte disorders: check serum potassium and sodium regularly.
• Concomitant antihypertensives: avoid excessive blood‑pressure lowering.
• Pregnancy and lactation: safety not established; use only if benefits outweigh risks.
• Store at ambient temperature: keep below 25°C, retain in original packaging, protect from moisture.

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

Major Interactions (Avoid)

• Non‑selective β‑blockers: additive bradycardia and hypotension.
• Potassium‑sparing diuretics or supplements: risk of hyperkalaemia.
• Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): increase nebivolol plasma levels.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may enhance hypotensive effect.
• NSAIDs: can reduce diuretic efficacy and impair renal function.
• Lithium: thiazide may increase lithium concentrations.
• Antidiabetic agents: thiazide may elevate blood glucose, requiring dose adjustment.
