[medical citation needed] The most common use of spironolactone is in the treatment of heart failure. [36] On its own, spironolactone is only a weak diuretic because it primarily targets the distal nephron ( collecting tubule ), where only small amounts of sodium are reabsorbed, but it can be combined with other diuretics to increase efficacy.
Spironolactone has been identified as an inhibitor of NRG1‐ERBB4 signaling. [142] Spironolactone has been found to act as a potent inhibitor of the pannexin 1 channel, and this action appears to be involved in its antihypertensive effects independently of MR antagonism. [143] Spironolactone has been found to block hERG channels. [144]
However, spironolactone is metabolized to three active metabolites, which give it prolonged activity (13.8 – 16. 5 hours). Spironolactone has a long half-life and is excreted 47-51% through kidneys.

Spirolactones are a class of functional group in organic chemistry featuring a cyclic ester attached spiro to another ring system. The name is also used to refer to a class of synthetic steroids, called steroid-17α-spirolactones, 17α-spirolactosteroids, or simply 17α-spirolactones, which feature their spirolactone group at the C17α position.
