Tenormin 25 mg 28 Tablets

Tenormin 25 mg (28 Tablets)

Active Ingredient:

• Atenolol 25 mg

Therapeutic Class:
Selective Beta₁-Adrenergic Blocker (Cardioselective Beta-Blocker)

Indications:

• Mild to moderate hypertension (high blood pressure)

• Angina pectoris (chronic chest pain)

• Cardiac arrhythmias (irregular heartbeats)

• Post-myocardial infarction (secondary prevention after heart attack)

• Sometimes used in anxiety-related tachycardia (off-label)

Dosage:

• Hypertension: Initial dose 25–50 mg once daily; may increase gradually to 100 mg/day if needed.

• Angina or arrhythmia: 25–50 mg once or twice daily, adjusted as required.

• Post-myocardial infarction: Often started with 25–50 mg twice daily, then 100 mg once daily maintenance.

• May be taken with or without food.

• Dosage adjustment is required in renal impairment.

Mechanism of Action:
Atenolol selectively blocks beta₁-receptors in the heart, leading to:

• Reduced heart rate and cardiac output

• Lowered blood pressure

• Decreased oxygen demand by the heart

• Stabilization of heart rhythm

Precautions:

• Contraindicated in:

  • Severe bradycardia or heart block

  • Cardiogenic shock

  • Uncontrolled heart failure

  • Known hypersensitivity to atenolol

• Use with caution in:

  • Diabetes mellitus (may mask low blood sugar symptoms)

  • Asthma or COPD (risk of bronchospasm)

  • Peripheral vascular disease (may worsen circulation)

  • Thyrotoxicosis (may mask tachycardia)

• Do not stop abruptly; taper gradually to avoid rebound angina or hypertension.

Possible Side Effects:

• Fatigue or dizziness

• Bradycardia (slow pulse)

• Cold hands and feet

• Nausea or mild gastrointestinal upset

• Hypotension (low blood pressure)

• Sleep disturbances or vivid dreams (uncommon)
