Who Supplies Natroba (spinosad) and What Companies Matter in the Value Chain
Natroba is the brand name for spinosad topical suspension (used for scabies and other parasitic indications). Supply responsibility in pharma typically splits into (1) active pharmaceutical ingredient (API) manufacturers, (2) formulation/fill-finish and contract manufacturers, and (3) marketing authorization holders (MAHs) / branded product owners. Publicly available patent and regulatory records do not provide a single, definitive global “supplier list” for Natroba across all countries and product lifecycles; the supplier set changes with each product listing, label revision, and manufacturing site designation.
What entity owns the Natroba brand?
Revon Healthcare is the company name that appears in public listings associated with Natroba as the branded product in the US market (NDC listing and label-linked product records).
Who manufactures Natroba? (Regulatory manufacturing roles)
For US distribution, Natroba’s supply chain typically involves contract manufacturing and packaging arranged under the label holder’s product application. Public data points that usually identify the “who manufactures” include:
- US FDA labeling sections that list manufacturer and packager (site-level)
- NDC directory entries that link to labeler/manufacturer codes
- For generic or parallel products, separate application histories and sites
No complete, country-wide supplier list for Natroba can be produced from the information provided in this prompt alone.
Which companies supply the spinosad drug substance (API)?
Spinosad is a fermentation-derived insecticidal product whose API sourcing is commonly split across specialized fermentation and purification suppliers. In pharma supply chains, API supply for spinosad is typically handled by one or more dedicated fermentation chemistry manufacturers, then shipped to formulation sites.
A complete API supplier roster for Natroba requires site-specific linkage to the Natroba manufacturing application and current FDA listing codes. The prompt does not include those records, and no single “official supplier list” exists as one static entity list for all markets.
What matters most for procurement (how to identify the real suppliers)?
For R&D diligence or investment-grade vendor mapping, suppliers should be verified through the following:
- FDA label “Manufactured for” / “Packaged by” sections for Natroba (US)
- NDC directory manufacturer codes linked to the specific NDC strength and presentation
- ANDA/505(b)(2) application supplements (if a generic or reformulated version exists) and site manufacturing history
- Batch release and stability documentation requested from the label holder or authorized distributor (for the current manufacturing year)
Supplier map by role (practical segmentation)
Below is the supplier-role framework used in pharma diligence. It is the correct structure to populate with verified company names once the NDC/label/manufacturing-site records are matched.
| Supply role |
What it controls |
What to verify in records |
| Brand owner / labeler (MAH) |
Regulatory responsibility, label, distribution rights |
NDC labeler name, label “manufactured for” references |
| Drug substance (spinosad API) supplier |
Fermentation and purification batch quality |
API manufacturer identity tied to the finished product application |
| Drug product formulator |
Formulation science and quality system for the suspension |
Finished product manufacturing site identity in label |
| Fill-finish and packaging contractor |
Bottle/tube fill, packaging components, labeling |
Packager listed on label and NDC manufacturing site |
| Secondary logistics and distribution |
Wholesaler and distribution lanes |
Authorized distributor network and lot supply cadence |
Key Takeaways
- Natroba is a branded topical spinosad product; supply chain responsibility splits across brand owner, API, formulation, and fill-finish roles.
- Revon Healthcare is the public-facing brand/labeling entity associated with Natroba in US listings.
- A defensible, named supplier roster for API and manufacturing cannot be completed from the prompt alone because supplier identity is site- and NDC-specific and changes across manufacturing years and markets.
FAQs
-
Is “Natroba supplier” the same as “spinosad API supplier”?
No. Brand product manufacturing (formulation, fill-finish, packaging) and API manufacturing are different roles with different suppliers.
-
Where do I find the real manufacturer of Natroba for a specific bottle?
The most direct proof is the Natroba label manufacturer/packager text and the corresponding NDC directory manufacturer code.
-
Do Natroba suppliers change over time?
Yes. Manufacturing sites, contractors, and sometimes packaging vendors can change while the label holder remains the same.
-
Can one company supply both API and the finished topical product?
It is possible, but uncommon in practice because API fermentation and finished topical suspension manufacturing typically run on different quality systems and facilities.
-
What is the fastest diligence path to identify suppliers for procurement?
Match the NDC to the labeler and manufacturer/packager entries, then confirm through batch documentation requests from the label holder or authorized distributor.
