Metoprololsuccinat Mylan (Metoprolol Tartrate)

Metoprolol tartrate selectively antagonises β1‑adrenergic receptors in the heart. By blocking the effects of adrenaline and noradrenaline, it slows the sinus node, reduces contractile force, and lowers cardiac output, which together lower systemic blood pressure and decrease myocardial oxygen consumption.

The appropriate dose is determined by the prescribing clinician based on the individual’s condition, age, renal function and response to therapy. Dosage may be started low and titrated upward, but exact regimens should only be set by a qualified healthcare professional.

Safety data are limited, and the pregnancy category is listed as unknown. Because β‑blockers can affect fetal growth and neonatal heart rate, the drug should only be used during pregnancy or lactation when the potential benefit justifies the potential risk and after consultation with a specialist.

Metoprolol is a cardio‑selective (β1‑specific) blocker, offering fewer respiratory side effects than non‑selective agents such as propranolol. It is commonly preferred for patients with hypertension or heart failure who also have mild asthma or COPD, whereas non‑selective blockers may be chosen for migraine prophylaxis or essential tremor.

Store the tablets at ambient temperature, preferably below 25 °C, in the original container to protect from moisture and light. Keep out of reach of children and do not use after the expiry date printed on the packaging.

The medication is taken orally, usually with a glass of water. It may be taken with or without food, but consistency with meals helps maintain stable absorption. Patients should follow the prescriber’s instructions regarding timing and whether the dose is taken once or twice daily.

Serious adverse events include severe bradycardia, heart block, marked hypotension, bronchospasm in susceptible individuals, and rare allergic reactions such as anaphylaxis. Patients should seek immediate medical attention if they experience fainting, severe shortness of breath, chest pain, or signs of an allergic response.

Metoprolol is contraindicated in patients with known hypersensitivity to the drug, those with severe bradycardia (heart rate < 45 bpm), second‑ or third‑degree atrioventricular block without a pacemaker, cardiogenic shock, and uncontrolled asthma or severe chronic obstructive pulmonary disease.
