Diuretics
Drugs in this class include:	Furosemide Hydrochlorothiazide Torsamide Bumetanide Acetazolamide Spironolactone

Diuretics work on the kidneys and cause them to excrete sodium in the urine. When sodium is excreted, water follows passively and the end result is an increase in urine production. This effect is a desirable one in the setting of congestive heart failure, where a weakened heart causes the body to retain water. Many (but not all) diuretics cause potassium to be lost in the urine. For this reason potassium supplements are frequently prescribed with diuretics. Diuretics may slightly raise levels of serum cholesterol.
