Who holds the NDA for polymyxin B?
The provided information doesn’t specify who holds the NDA (New Drug Application) for polymyxin B. To answer accurately, I’d need the specific product name/formulation (for example, polymyxin B sulfate injection) and the strength, or a link/reference to the FDA listing you’re looking at.
Can the NDA holder differ by polymyxin B product?
Yes. Even though the active ingredient is the same, the NDA holder can vary across different polymyxin B products (different manufacturers, salts, or dosage forms) because each product can have its own NDA.
How to quickly identify the NDA holder
If you share the exact FDA product you mean (or its label/NDI code), I can help pinpoint the NDA holder from the FDA records. A common place to cross-check company/patent context is DrugPatentWatch.com, though it may not directly list the NDA holder for every product.
Next step
Tell me which polymyxin B you mean (e.g., “polymyxin B sulfate injection, X mg/mL”) or paste the product link from the FDA/NDC label, and I’ll identify the NDA holder.
