Metoprolol Z Hexal (Metoprolol Tartrate)

Metoprolol Z Hexal, a selective β1‑adrenergic blocker, is used in several cardiovascular conditions.

• Hypertension: lowers systolic and diastolic pressure, decreasing long‑term cardiovascular risk.
• Angina pectoris: reduces myocardial oxygen demand, relieving chest pain during exertion.
• Post‑myocardial infarction: improves survival by limiting adverse cardiac remodeling.
• Chronic heart failure: enhances ventricular function and reduces hospitalisation rates.
• Cardiac arrhythmias: controls heart rate in supraventricular tachyarrhythmias.

• Metoprolol Tartrate selectively antagonises β1‑adrenergic receptors in cardiac tissue, decreasing cyclic AMP formation. This leads to reduced intracellular calcium, slowing sino‑atrial node firing, lowering myocardial contractility and heart rate, and ultimately diminishing cardiac output and systemic blood pressure.

Metoprolol Z Hexal may cause a range of adverse reactions. Patients should be aware of both frequent and less common events.

Common Side Effects

• Fatigue: feeling of tiredness or lack of energy.
• Dizziness or light‑headedness, especially when standing quickly.
• Bradycardia: slower than normal heart rate.
• Cold extremities: reduced peripheral circulation.
• Gastrointestinal upset: nausea, abdominal discomfort.
• Headache: mild to moderate intensity.

Serious or Rare Side Effects

• Severe bradycardia or heart block requiring medical attention.
• Marked hypotension leading to fainting or shock.
• Bronchospasm in patients with reactive airway disease.
• Allergic reactions such as rash, itching, or angioedema.
• Depression or mood changes.
• Worsening of heart failure symptoms.

Before initiating therapy, several safety considerations should be reviewed.

• Dose adjustment in renal impairment: reduce the dose according to renal function.
• Monitor heart rate and blood pressure: regular checks are essential during titration.
• Avoid abrupt discontinuation: taper the dose under medical supervision to prevent rebound tachycardia.
• Caution in asthma or COPD: β1‑selectivity may still affect bronchial tone.
• Use with caution in diabetes: may mask typical hypoglycaemia symptoms.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Metoprolol Z Hexal can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Non‑selective beta blockers: additive bradycardia and hypotension.
• Calcium channel blockers (verapamil, diltiazem): increased risk of AV‑block.
• Clonidine: abrupt withdrawal may cause rebound hypertension.
• Insulin or oral hypoglycaemic agents: may mask hypoglycaemia signs.

Moderate Interactions (Monitor Closely)

• Diuretics: may enhance the hypotensive effect.
• ACE inhibitors or ARBs: additive blood‑pressure lowering.
• SSRIs or other antidepressants: possible increase in bradycardia.
