Generic: Rauwolfia Alkaloid and Thiazide Diuretic Combination
Rauwolfia alkaloid and thiazide diuretic combinations are prescription-only products used in patients with high blood pressure (hypertension).
Unchecked hypertension for a prolonged time causes “extra” workload on the heart and blood vessels, resulting in damages to the blood vessels of the brain, heart, and kidneys. Over time, hypertension can lead to a stroke, heart failure, or kidney failure.
Rauwolfia alkaloids lower your blood pressure by depressing the central nervous mechanisms whereas thiazide diuretics (water pills) work by increasing the rate of urine formation. Both these actions have combined effect in reducing the blood pressure.
