What is this medication?

Atenolol+Chlorthalidone, Tenoretic
Antihypertensive; Beta-Blocker; Beta 1 Specific; Thiazide-Related Diuretic

Atenolol+Chlorthalidone, Tenoretic is officially indicated for the treatment of hypertension.

How does this medication work? 

Beta 1 receptor is activated by adrenaline and is involved with cardiac output by increasing the volume of each pump as well as increasing the heart rate.  Atenolol works by blocking this receptor and has the reverse effect thereby reducing heart rate and stroke volume.

Chlorthalidone inhibits sodium and chloride reabsorption in the distal convoluted tubule resulting in a diuretic effect.  Sulfonamide derived agent.

How should I take this medication? 

Oral: Initial: Atenolol 50 mg/chlorthalidone 25 mg once daily; if optimal blood pressure response not achieved, may increase to atenolol 100 mg/chlorthalidone 25 mg once daily.

How to Take: Follow instructions provided by physician/pharmacy label, take consistently at same times each day unless otherwise directed, store at room temperature. Preferably taken in the morning to avoid nocturia due to diuretic effect.

You Need to Avoid: Careful standing up too quickly as you may get dizzy.
Do not stop this medication abruptly to avoid rebound tachycardia, hypertension and in severe cases angina, heart attack, or arrhythmia.
