Metoprolol Hexal Z Hexal (Metoprolol Tartrate)

Metoprolol Tartrate is a selective β1‑adrenergic blocker that acts on the cardiovascular system to control pressure and rhythm.

• Hypertension: lowers systolic and diastolic blood pressure by reducing heart rate and cardiac output.
• Angina pectoris: decreases myocardial oxygen demand, relieving chest pain during exertion.
• Post‑myocardial infarction: improves survival by limiting ventricular remodeling and reducing recurrent ischemic events.
• Chronic heart failure: enhances left‑ventricular function and reduces hospitalisation risk.
• Cardiac arrhythmias: controls ventricular rate in atrial fibrillation and other supraventricular tachyarrhythmias.

• Metoprolol Tartrate selectively antagonises β1‑adrenergic receptors in cardiac tissue, inhibiting catecholamine‑induced stimulation of adenylate cyclase. This reduces intracellular cyclic AMP, leading to decreased calcium influx, slower sino‑atrial node firing, reduced myocardial contractility, and lower cardiac output, ultimately lowering blood pressure and heart rate.

Metoprolol Tartrate may cause a range of adverse reactions, from mild to serious.

Common Side Effects

• Fatigue or tiredness
• Dizziness or light‑headedness
• Bradycardia (slow heart rate)
• Cold extremities
• Gastrointestinal upset (nausea, abdominal discomfort)
• Sleep disturbances or vivid dreams

Serious or Rare Side Effects

• Severe bradycardia or sinus arrest
• High‑grade atrioventricular block
• Symptomatic hypotension
• Bronchospasm in patients with reactive airway disease
• Allergic reactions (rash, angioedema, anaphylaxis)
• Depression or mood changes

Before prescribing Metoprolol Tartrate, clinicians should evaluate patient‑specific factors and monitor for adverse events.

• Cardiovascular assessment: check baseline heart rate, blood pressure, and conduction abnormalities.
• Respiratory caution: avoid in patients with severe asthma or chronic obstructive pulmonary disease.
• Diabetes monitoring: be aware that beta‑blockade may mask hypoglycaemia symptoms.
• Concomitant medications: review for drugs that also lower heart rate or blood pressure.
• Pregnancy and lactation: use only if potential benefit justifies potential risk, as safety data are limited.
• Store at ambient temperature: keep below 25°C in the original container, protect from moisture and direct sunlight.

Metoprolol Tartrate can interact with several 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 and severe bradycardia.
• Clonidine: abrupt discontinuation may precipitate rebound hypertension.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may enhance hypotensive effect, requiring dose adjustment.
• Diuretics: risk of electrolyte disturbances and excessive blood pressure reduction.
• Antidiabetic agents (insulin, sulfonylureas): beta‑blockade can mask hypoglycaemia signs, necessitating closer glucose monitoring.
