Composition of Aten 100

Aten 100 contains Atenolol (100mg). It belongs to the Beta-blocker (beta-1 selective) class of medicines.

Uses of Aten 100

  • Hypertension (high blood pressure)
  • Prevention
  • Management of angina (chest pain) due to coronary artery disease
  • Rate control in certain tachyarrhythmias (as prescribed)

Benefits of Aten 100

In High blood pressure
Aten slows the heart a little and lets it beat with less force, bringing blood pressure down and reducing the long-term risk of stroke and heart attack.
In Angina
Aten reduces how hard the heart has to work, so it needs less oxygen and you get fewer episodes of chest pain on exertion.
In Heart failure
Aten protects a weakened heart from the stress hormones that would otherwise strain it further, improving how well it pumps over time and lowering the risk of hospital admission.
In Irregular heartbeat
Aten steadies the heart's rhythm and keeps the rate from racing, which eases palpitations and the dizziness or breathlessness that come with them.

How Aten 100 works

Atenolol is a cardioselective beta-1 blocker. It reduces heart rate and the force of contraction, lowering cardiac output and blood pressure, and decreases the heart’s oxygen demand to relieve angina.

How to take Aten 100

Tablet for oral use. Take exactly as prescribed, usually once daily, with or without food, at the same time each day. Do not stop abruptly; dose should be tapered under medical advice.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
