Are diuretics used for other purposes?
Diuretics have several other uses in addition treating edema.
- A diuretic may be used as part of the treatment program for patients with hypertension. (High blood pressure may be caused by salt retention, or caused by some antihypertensive medications). In fact, most medications that dilate the blood vessels and reduce blood pressure, except for ACE inhibitors and angiotensin receptor blockers, lead to secondary salt retention by the kidneys.
- Thiazide diuretics also have been used to prevent the formation ofkidney stones. These drugs reduce the urinary excretion of calcium, which is a component of the kidney stone.
- Acetazolamide (Diamox) taken a few days before going to high altitudes, appears to reduce the tendency for people to develop altitude sickness.
