Lanoc

Metoprolol tartrate, the active ingredient in Lanoc, is a beta‑adrenergic blocking agent presented as an oral tablet for oral administration. It reduces heart rate, myocardial contractility, and cardiac output, thereby lowering blood pressure, decreasing myocardial oxygen demand, and stabilising cardiac rhythm in adult patients with hypertension, angina, heart failure, or arrhythmias.

GNH USA supplies Lanoc as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation for global distribution.

Metoprolol tartrate is used to manage several cardiovascular conditions by modulating heart rate and blood pressure.

Hypertension: controls high blood pressure by reducing cardiac output. Angina pectoris: relieves chest pain by decreasing myocardial oxygen demand. Myocardial infarction: improves survival after heart attack by limiting cardiac workload. Heart failure: supports ventricular function by lowering heart rate and afterload. Cardiac arrhythmias: stabilises abnormal heart rhythms by blocking β1 receptors.

Metoprolol tartrate may cause a range of adverse reactions, which are classified by frequency and severity.

Common Side Effects: - Fatigue - Dizziness - Cold extremities - Bradycardia - Gastrointestinal discomfort

Serious or Rare Side Effects: - Severe bradycardia - Heart block - Hypotension - Bronchospasm - Depression or mood changes

Metoprolol tartrate requires careful assessment and monitoring to minimise risks.

Assess cardiovascular status: evaluate heart rate and blood pressure before initiating therapy. Monitor for bronchospasm: use cautiously in patients with asthma or COPD. Review renal and hepatic function: dose adjustments may be needed in impairment. Avoid abrupt discontinuation: taper gradually to prevent rebound tachycardia. Caution with diabetes: may mask hypoglycaemia symptoms. Store below 25°C: keep in the original container, protect from moisture.

Metoprolol tartrate can interact with several drug classes, necessitating vigilance.

Major Interactions (Avoid): - Concomitant use with non‑selective beta‑blockers: may cause excessive bradycardia. - Combined with calcium channel blockers (verapamil, diltiazem): risk of severe heart block. - Interaction with clonidine withdrawal: may precipitate hypertensive crisis.

Moderate Interactions (Monitor Closely): - Antihypertensive agents (ACE inhibitors, diuretics): monitor blood pressure. - Antidiabetic drugs (insulin, sulfonylureas): watch for concealed hypoglycaemia. - CYP2D6 inhibitors (paroxetine, fluoxetine): may increase metoprolol levels. - NSAIDs: may reduce antihypertensive effect.
