Aldactone is the brand name for spironolactone, a potassium-sparing diuretic. “Aldactone suppliers” depends on what you mean by supplier: the manufacturer of the branded product, the active pharmaceutical ingredient (API) supplier, or the finished-dose contract manufacturing/labeler supplying specific markets. The same drug can also be supplied by multiple generic manufacturers under the same active ingredient.
Which companies supply Aldactone (spironolactone) finished product?
The supply chain for aldactone-branded product varies by country and distribution channel, and direct supplier lists are not standardized across jurisdictions. As a result, the only robust way to identify “suppliers” is to rely on official drug listing and labeler/manufacturer disclosures for each market.
Without market and regulatory jurisdiction, a complete and accurate supplier list cannot be produced.
Which firms supply spironolactone API (active ingredient) used to make Aldactone?
Spironolactone API is supplied by multiple chemical and API manufacturers globally. Aldactone-branded tablets require finished-dose manufacturing and quality-controlled API sourcing, but the specific API supplier for “Aldactone” in any given market is not published as a single global roster in public sources.
Without a market-specific labeler/manufacturer and product strength/form tied to a specific jurisdiction, a complete and accurate API supplier mapping cannot be produced.
What supplier signals can be used for due diligence (practical screening checklist)?
The most defensible approach is to validate suppliers through regulatory and dossier-linked identifiers that map to actual marketed product manufacture:
- Labeler and manufacturer on the product pack (country-specific).
- Marketing authorization holder and manufacturing site(s) listed in local drug registers.
- API manufacturer(s) named in regulatory submissions when publicly disclosed (varies by country).
- GMP site inspections and compliance history for the specific manufacturing locations tied to the marketed product.
Regulatory references that identify branded product entities
To build a supplier list, you anchor to the registered product entry for aldactone/spironolactone in the target jurisdiction (labeler, MAH, and listed manufacturing sites). Public regulatory datasets provide the “manufacturer of record” for the marketed product, not the API chemical vendor.
Key Takeaways
- “Aldactone suppliers” is not a single fixed list because it varies by market and which layer of the supply chain (finished dose vs API) you mean.
- A complete, accurate supplier roster requires grounding in market-specific product listings that name the labeler/marketing authorization holder and manufacturing sites.
- Public data generally supports identifying the finished-dose manufacturer and sites more consistently than the exact API supplier used for a specific branded batch.
FAQs
-
Is Aldactone the only spironolactone brand?
No. Multiple brands and generics use spironolactone.
-
Do API suppliers for spironolactone stay the same for Aldactone?
They can change by contract manufacturing and sourcing strategy, and the exact API vendor is often not publicly tied to a branded product listing.
-
What is the most reliable way to identify the real Aldactone finished-product supplier?
The product pack label and the national drug register entry for the specific market.
-
Can I get a global list of API suppliers for spironolactone?
You can find multiple API makers generally, but a complete “Aldactone-specific” supplier mapping requires market and product registration linkage.
-
Does Aldactone supply differ by tablet strength or dosage form?
Yes. Different strengths or dosage forms can be manufactured at different sites under separate registrations.
