Aten 100 mg Tablet

Aten 100 mg Tablet is a prescription tablet that contains 100 mg of atenolol in each tablet. Atenolol is a beta-blocker used to help manage high blood pressure, angina (chest pain), and certain heart rhythm problems, and it may also be used after a heart attack in some patients. Aten 100 mg Tablet is a higher-strength option, so it is generally chosen for people whose doctor has already assessed their response to lower strengths such as Aten 25 mg Tablet or Aten 50 mg Tablet. This 100 mg tablet is meant to provide a fuller dose in a single tablet when that is appropriate for the treatment plan.

How it works: Atenolol in Aten 100 mg Tablet works by blocking beta receptors in the heart, which slows the heart rate and lowers the force of each heartbeat. As a tablet, it is swallowed and absorbed into the body to help reduce blood pressure and decrease the heart's workload over time.

Aten 100 mg Tablet delivers twice the amount found in Aten 50 mg Tablet and four times the amount found in Aten 25 mg Tablet, so it is not the usual starting strength for many patients. Doctors may choose Aten 100 mg Tablet for people who need stronger blood pressure or heart-rate control and who have already tolerated lower doses well. Because it is a higher-strength atenolol tablet, it may have a stronger effect on pulse rate and blood pressure, so it should be used only as directed.

• High blood pressure
• Angina (chest pain)
• Certain fast or irregular heart rhythms
• After heart attack in selected patients

• Swallow Aten 100 mg Tablet whole with a glass of water; do not crush or chew unless your prescriber specifically tells you to.
• Take it at the same time each day to help maintain a steady effect.
• It may be taken with or without food, but taking it the same way each day can help consistency.
• Do not stop taking Aten 100 mg Tablet suddenly, because stopping beta-blockers abruptly can worsen chest pain or raise heart rate.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up.
• Follow your doctor’s directions exactly, especially because this is the 100 mg strength and may be too strong for people who have not been titrated up.

Aten 100 mg Tablet provides 100 mg of atenolol in each tablet. Depending on the condition being treated, it may be taken once daily or divided into two doses, but the exact schedule is set by the doctor. The maximum daily dose depends on the patient and the reason for treatment, so do not change the amount or frequency on your own.
