Treating high blood pressure. Tenoretic is a beta-blocker and diuretic combination. It works by interfering with certain body chemicals that cause the heart to beat with less force and pump out less blood. This allows the heart to beat more slowly and regularly. By blocking these chemicals, blood vessels are relaxed and widened, allowing blood pressure to decrease. The diuretic works by causing the kidney to eliminate larger-than-normal amounts of water.
Tenoretic is a Diuretic and Beta-Blocker combination drug that is used in the treatment of high blood pressure. Tenoretic contains two drugs, chlorthalidone and atenolol, which work in different ways to reduce high blood pressure. Tenoretic works by reducing the patient's heart rate and expanding the blood vessels to allow blood flow through the body with minimum resistance.
