Nebivolol + Hydrochlorothiazide

Indications

Essential hypertension

Pharmacology

The Combination of these ingredients has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone. This combination has mild vasodilating properties which reduces heart rate and blood pressure in hypertensive patients. Hydrochlorothiazide affects the renal tubular mechanisms of electrolyte reabsorption which directly increase the excretion of sodium and chloride in approximately equivalent amounts. The diuretic action of Hydrochlorothiazide reduces plasma volume, increases plasma renin activity and increases aldosterone secretion.

Dosage And Administration

Once daily, preferably at the same time every day.

Interaction

Nebivolol:

  • Class I & III Antiarrhythmics, Calcium channel blocker (Verapamil/Diltiazem)
  • Centrally-acting antihypertensives, Anaesthetics
  • Antipsychotics, Antidepressants, NSAIDs

Hydrochlorothiazide:

  • Drugs affecting Potassium & Calcium level
  • Non-steroidal anti-inflammatory drugs (NSAIDs)
  • Concomitant administration of this combination with Antipsychotics, Tricyclic Antidepressants & Barbiturates may enhance the hypotensive effect and lead to postural hypotension.

Contraindications

Hypersensitivity to the active substances, Liver function impairment. Severe renal insufficiency (Creatinine clearance < 30 ml/min.), Bradycardia, Hypotension.

Side Effects

Nebivolol: Headache, Dizziness, Tiredness, Diarrhoea, Constipation, Nausea etc.

Hydrochlorothiazide: Vertigo, Itchiness, Rash, Increased sensitivity of skin to sunlight etc.

Pregnancy And Lactation

This combination is not recommended during pregnancy. It is also not recommended for mothers who are breast-feeding.

Precautions And Warnings

Nebivolol: Beta-blockers should not be used in patients with untreated Congestive Heart Failure (CHF) & bradycardia. In patients with Chronic Obstructive Pulmonary Diseases (COPD), beta-blockers should be used with caution as airway constriction may be aggravated.

Hydrochlorothiazide: In patients with renal disease, thiazides may increase azotaemia. If progressive renal impairment becomes evident, careful reappraisal of therapy is necessary. Thiazides can cause fluid or electrolyte imbalance. Thiazides may decrease urinary calcium excretion and may cause slight elevation of serum calcium in the absence of known disorders of calcium metabolism.

Overdose Effects

No data are available on Overdosage. Overdosage with Hydrochlorothiazide is associated with electrolyte depletion and dehydration resulting from excessive diuresis.

Therapeutic Class

Combined antihypertensive preparations

Use in special populations

Use in children is not recommended.

Storage Conditions
