Who supplies the active ingredient for EPIDIOLEX?
EPIDIOLEX is a branded cannabidiol (CBD) oral solution. The active pharmaceutical ingredient is pharmaceutical-grade CBD sourced from cannabis/hemp supply chains under regulated controls. The specific named raw-material suppliers used across EPIDIOLEX commercial production are not consistently disclosed in public filings at the granularity of “vendor name to dosage form lot.”
Who manufactures EPIDIOLEX drug product (oral solution)?
Public corporate and regulatory records identify the commercial manufacturing party for EPIDIOLEX drug product, but do not reliably publish an exhaustive supplier list (every sub-supplier in the formulation chain) in one place.
The following are the key, publicly documented manufacturing roles most investors and R&D teams use to map the supply chain for branded oral cannabis medicines:
| Supply-chain layer |
Role in EPIDIOLEX |
Supplier identification in public sources |
| API (CBD) supply |
CBD raw material for drug substance |
Public sources confirm CBD sourcing exists but typically do not list named CBD vendors at full supply-chain depth |
| Drug product (filled oral solution) manufacturing |
Final formulation, filling, packaging |
Public records identify manufacturing sites/companies, but do not always expose every upstream component supplier |
| Packaging components |
Bottles, caps, droppers, labels |
Public sources typically do not list named packaging vendors in a single consolidated list |
What manufacturing entities are tied to EPIDIOLEX in regulator-facing documents?
The most defensible way to identify EPIDIOLEX suppliers is via regulatory labels, drug establishment listings, and corporate manufacturing disclosures that name facilities and manufacturing organizations. Those documents generally identify:
- Drug product manufacturing site(s) and the legal manufacturer responsible for release.
- Roles such as packaging, labeling, and secondary packaging.
- Quality system responsibility for commercial lots.
Without direct access to the specific regulator-facing “supplier-of-record” tables for each market (US FDA label history, EMA EPAR annexes, and local drug establishment listings), a complete, vendor-name-by-vendor-name supplier roster cannot be produced without risking inaccuracies.
What can be concluded from the supply-chain structure for EPIDIOLEX?
For EPIDIOLEX, supplier discovery is built around four procurement buckets:
- Pharmaceutical-grade CBD (drug substance)
- Excipients used in the oral solution (solubilizers, sweeteners, flavorants, pH adjusters)
- Manufacturing and filling at GMP sites
- Packaging components compatible with dosing accuracy and stability requirements
These buckets mirror how cannabis-derived medicines are built in GMP documentation. Public disclosures generally name the accountable manufacturing organizations, while upstream raw-material supplier names are often controlled as trade/process information and vary by lot.
Key Takeaways
- EPIDIOLEX is an oral solution of cannabidiol (CBD), so the primary supplier question is the pharmaceutical-grade CBD (API) supply chain plus GMP drug-product manufacturing.
- Public sources consistently confirm the existence of regulated CBD sourcing and identify accountable manufacturing roles, but they do not provide a single, complete, vendor-name supplier list for every upstream component in the formulation and packaging chain.
- A defensible supplier map for EPIDIOLEX is facility- and role-based (API source category, drug product manufacturer, packaging/labeling roles), derived from market regulator filings and GMP listings rather than informal or marketing-level references.
FAQs
-
Is EPIDIOLEX supplied by a single CBD manufacturer?
Public disclosures typically confirm CBD supply under controlled sourcing, but do not always list a single named CBD vendor for all production runs.
-
Are packaging suppliers named for EPIDIOLEX in public documents?
Packaging and labeling component vendors are often not published as a consolidated supplier list for commercial cannabis medicines.
-
Where do you identify the drug-product manufacturer for EPIDIOLEX?
In regulator-facing documents tied to marketing authorization and GMP manufacturing listings, which identify the accountable manufacturing organization and site.
-
Can excipient suppliers be confirmed publicly for EPIDIOLEX?
Excipients used in the oral solution are generally listed in regulatory labeling, but upstream excipient vendor identities are often not enumerated.
-
What is the most reliable approach to mapping EPIDIOLEX suppliers?
Use regulator filings and GMP establishment listings to identify manufacturing sites and responsible parties, then map upstream categories (API, excipients, packaging) to the controlled supply chain.
