Furosemide is a powerful diuretic that acts on the kidneys to increase urination.
Often it is administered for people who have some form
of kidney failure, heart failure or to remove water
accumulation from tissues (in rare cases). It is also
used to remove mammary tissue in dogs suffering from
false pregnancy.
Recently, furosemide made headlines when two
rhythmic gymnasts tested positive for the drug at the
2001 Goodwill Games.
