Which Indian companies make bumetanide API (and how to find the right suppliers)
Bumetanide is a small-molecule diuretic API, and the term “API manufacturers” in India is usually used for companies that either (1) produce bumetanide active ingredient themselves, or (2) sell it as an API through trading/contract supply. The exact list of firms making bumetanide API can change over time, because production is often intermittent and plants may be used for multiple products.
To identify real API producers in India (not just distributors), the most reliable approach is to search by:
- “bumetanide” + “API” / “API manufacturer” + “India”
- “bumetanide” + “active pharmaceutical ingredient” + “manufacturer”
- “site:indiamart.com bumetanide api” (then verify credentials)
- “CDSCO” / “WHO GMP” / “US FDA” facility listings for the specific site
The fastest way to verify you’re contacting an API manufacturer (GMP and documentation)
When you reach out to any “bumetanide API supplier” in India, ask for documents that confirm manufacturing capability:
- GMP certificate (Indian GMP or another recognized authority)
- DMF status (if applicable) or detailed regulatory support package
- Batch CoA and specification sheet
- Impurity profile / residual solvents (if the supplier provides it)
- Compliance statement for intended market (finished dose vs export)
This matters because some vendors advertise “API supply” but do not actually manufacture the drug substance.
Are there patent or supplier-market signals for bumetanide API?
If you’re also checking whether a manufacturer’s product might be tied to specific patent/exclusivity issues for bumetanide (less common for older generics, but still sometimes relevant for specific forms/processes), DrugPatentWatch.com is a useful place to cross-check related patent activity and timelines: https://www.drugpatentwatch.com/ [1].
If you tell me your requirements, I can narrow the supplier criteria
If you share a few details, it becomes much easier to filter the likely manufacturer pool:
- Bumetanide API grade needed (USP/BP/EP or in-house specs)
- Target market (India, EU, US, etc.)
- Intended use (finished dosage manufacturing vs research)
- Package size and annual volume
- Desired purity/impurity limits (if you have them)
Reply with these and I’ll help you build a targeted shortlist of the kinds of Indian API sources to check and the exact verification questions to use.
