Co-amilofruse

Co-amilofruse (BAN) is a non-proprietary name used to denote a combination of amiloride and the formerly named frusemide (now the INN termed furosemide). Co-amilofruse in the treatment of fluid retension (oedema), either in the legs (peripheral edema) or on the lungs (pulmonary oedema). The stronger furosemide loop diuretic has a tendency to cause low potassium levels (hypokalaemia) that may be prevented by the potassium-sparing effects of amiloride.
