Potassium canrenoate

Potassium canrenoate (INN, JAN) or canrenoate potassium (USAN) (brand names Venactone, Soldactone), also known as aldadiene kalium,[1] the potassium salt of canrenoic acid, is an aldosterone antagonist of the spirolactone group.[2] Like spironolactone, it is a prodrug, and is metabolized to active canrenone in the body.[3][4]

Potassium canrenoate is notable in that it is the only clinically used antimineralocorticoid which is available for parenteral administration (specifically intravenous)[4][5] as opposed to oral administration.[6]

In the UK it is unlicensed and only used for short term diuresis in oedema or heart failure in neonates or children under specialist initiation and monitoring.
