Information About Aten Tablet (Atenolol)

Aten Tablet, also known as Atenolol, is a medication that belongs to the class of beta-blockers. It is commonly prescribed for the management of various cardiovascular conditions. Atenolol works by blocking the action of certain natural substances in the body, such as adrenaline, which helps to reduce heart rate and lower blood pressure.

Atenolol is primarily used to treat hypertension (high blood pressure) and angina (chest pain). It can also be prescribed to prevent heart attacks, treat irregular heart rhythms, and manage symptoms related to hyperthyroidism. Tenormin is a brand name for the generic medication Atenolol. It is one of the most commonly prescribed formulations of Atenolol available on the market. Tenormin shares the same active ingredient, Atenolol, and provides the same therapeutic effects. It is manufactured by various pharmaceutical companies and is widely used for the treatment of cardiovascular conditions.

Atenolol Tablet Benefits:

Blood pressure management: Atenolol helps to lower blood pressure, reducing the strain on the heart and improving overall cardiovascular health.

Angina relief: Atenolol can alleviate chest pain associated with angina by improving blood flow to the heart muscles.

Prevention of heart attacks: Atenolol may be prescribed to individuals who are at risk of a heart attack to help reduce the likelihood of a cardiovascular event.

Treatment of irregular heart rhythms: Atenolol can help regulate abnormal heart rhythms, such as atrial fibrillation, by slowing down the heart rate.

Symptom management in hyperthyroidism: Atenolol may be used in combination with other medications to manage symptoms caused by an overactive thyroid gland.

It is important to note that the use of Atenolol should be under the guidance of a healthcare professional, as they will determine the appropriate dosage and duration of treatment based on individual needs and medical history.

Dosage of Atenolol Tablet:

The dosage of Atenolol tablet can vary depending on the specific condition being treated and individual patient factors. It is essential to follow the prescribed dosage instructions provided by a healthcare professional. The usual recommended starting dose for hypertension is 50 mg taken orally once daily. However, the dosage can range from 25 mg to 100 mg per day, depending on the individual's response and medical condition.

For the treatment of angina or to prevent heart attacks, the typical dosage is also 50 mg taken orally once daily. Again, the dosage can be adjusted based on the individual's response and the guidance of the healthcare provider. It is important not to exceed the recommended dosage unless advised by a healthcare professional. Abruptly stopping the medication can be harmful, and it is generally recommended to gradually reduce the dosage under medical supervision when discontinuing Atenolol.

How Atenolol Tablet Works:

Atenolol belongs to a class of medications called beta-blockers. It works by blocking the effects of adrenaline (epinephrine) and other stress hormones on the beta receptors in the body. This action primarily affects the beta-1 receptors located in the heart, leading to the following effects:

Reduced heart rate: Atenolol slows down the heart rate, which helps in reducing the workload on the heart and improving its efficiency.

Decreased contractility: Atenolol reduces the force of contraction of the heart muscles, resulting in a decrease in the amount of oxygen the heart requires and a reduction in the workload on the heart.

Lowered blood pressure: Atenolol relaxes and widens the blood vessels, allowing blood to flow more easily. This helps to lower blood pressure by reducing the resistance against which the heart pumps blood.

It is important to note that the mechanism of action of Atenolol is specific to beta receptors, and it does not affect other receptors or hormones in the body. The exact dosage and treatment plan should be determined by a healthcare professional based on the individual's specific condition, medical history, and response to the medication.
