Atenolol with diuretics is a combination preparation of atenolol, which is a beta-blocker, with one or more diuretics or 'water tablets'. It is used to treat hypertension (high blood pressure).

Atenolol works by blocking chemical messages to the heart which slows down the activity of the heart, decreasing blood pressure.

The diuretic removes excess water from the body by increasing how much and how often you pass water. This removal of fluid reduces the blood pressure.
