Other molecules FDA puts in Aldosterone Antagonist, with whether each is in shortage right now. Same class is not the same drug — substitution is a clinical decision, and this is a supply picture, not a recommendation.
Common questions

- What does Spironolactone cost?
- The typical pharmacy pays about $0.0846 per unit, based on the most recent CMS NADAC survey of actual acquisition costs. That is what the pharmacy pays for the drug itself — not the cash price, and not what an insurer is billed.
