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.
