Treatment of Hypertension or High Blood Pressure

Atenolol Chlorthalidone is a combination medicine prescribed by most doctors for the treatment of hypertension or high blood pressure. It is made up of Atenolol, a beta-blocker, and Chlorthalidone, a diuretic. Atenolol affects the circulation of the blood while Chlorthalidone helps prevent the body from absorbing too much salt.

It’s one of the most commonly used beta-blockers/ diuretic. It’s a first-choice treatment for heart attack recovery and angina pectoris particularly to those with kidney problems and heart diseases. At a lower dose, this medication has fewer side effects compared with other drugs of its kind. The combination was approved for medical use by the FDA since 1984.

What condition does Atenolol Chlorthalidone treat?

Atenolol is used for the treatment of high blood pressure. High blood pressure or hypertension is a common condition that nearly half of American adults have it. It occurs when your blood pressure increases to an abnormal and unhealthy level. High blood pressure typically develops over the course of several years oftentimes without symptoms. Even without symptoms, damage to your blood vessels and heart continues.
