Uses / Indications

Aten 100mg Tablet is prescribed for:

• Hypertension (High Blood Pressure) – especially in patients not controlled by lower doses.

• Angina (chest pain due to reduced oxygen supply to the heart)

• Arrhythmias (irregular heartbeat)

• Migraine prevention (off-label use)

• Anxiety-related palpitations & tremors (off-label use)

Mechanism of Action

• Atenolol is a Beta-1 Selective Blocker.

• Slows down the heart rate & reduces the force of contraction → lowers BP.

• Reduces oxygen demand of the heart → relieves angina.

• Controls abnormal rhythms and prevents cardiac complications.

• Provides long-term cardiovascular protection.

Dosage & Administration

• Usual adult dose: 25–100 mg once daily (may be given in divided doses).

• 100 mg once daily is the maximum usual dose for hypertension and angina.

• Should be taken at the same time daily.

• Can be taken with or without food.

• Do not discontinue abruptly – may cause rebound hypertension, angina, or arrhythmias.
