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]
Spironolactone is commonly used in the treatment of hirsutism in women, and is considered to be a first-line antiandrogen for this indication. [68] Spironolactone can be used in the treatment of female-pattern hair loss (pattern scalp hair loss in women). [69] There is tentative low quality evidence supporting its use for this indication. [70]
Here’s a little cheat sheet on androgenetic alopecia: ... other medications like spironolactone may be prescribed off-label for hair loss. This is typically only used in women and not in men ...
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. Patients with chronic kidney disease therefore require close monitoring when taking the drug. Spironolactone is also eliminated through feces (35-41%
[191] [62] However, spironolactone was introduced in 1959., [192] [193] although its antiandrogen effects were not recognized or taken advantage of until later and were originally an unintended off-target action of the drug. [194] In addition to spironolactone, chlormadinone acetate and megestrol acetate are steroidal antiandrogens that are ...
The Randomized Aldactone Evaluation Study (RALES) trial is a landmark clinical study that assessed the impact of spironolactone, an aldosterone antagonist, on morbidity and mortality in patients with severe heart failure due to systolic dysfunction. [1] The findings from this trial significantly influenced the treatment guidelines for heart ...
Indications and Usage - uses (indications) for which the drug has been FDA-approved (e.g. migraines, seizures, high blood pressure). Physicians legally can and often do prescribe medicines for purposes not listed in this section (so-called " off-label uses ").
Indications can impact the pricing of medications through Value-based Pricing, also known as indication specific pricing or indication value-based pricing.
