VECTICAL (Calcitriol) Suppliers: Who Manufactures and Supplies the Drug and APIs?
VECTICAL is a brand of calcitriol indicated for psoriasis. Supplier identification depends on the specific manufacturer/marketer listed on the FDA label and the latest FDA listing (NDC/labeler); without those identifiers, a complete and accurate “who supplies what” map cannot be produced.
Who supplies VECTICAL (calcitriol) in the US?
Answer: VECTICAL supply is tied to the NDC labeler shown on the FDA product label (DailyMed/FDA label) and the listed drug manufacturer(s) associated with those NDCs. Those entries determine the commercial supply chain.
What entities typically appear as suppliers
- Finished-dose manufacturer (site that manufactures VECTICAL drug product)
- Labeler/marketer (sells under the brand and appears on NDC labeling)
- Private-label and relabeling distributors (if applicable)
- API supplier for calcitriol (often multiple, but typically not fully disclosed publicly)
Which companies manufacture calcitriol used in VECTICAL?
Answer: Multiple industrial calcitriol API producers typically exist, but the specific API supplier(s) used for a given VECTICAL NDC can only be confirmed from:
- FDA labeling that discloses the applicant/manufacturer chain for that NDC, or
- supplier qualification documentation (commercial)
Without the specific VECTICAL NDC(s) and corresponding labeler/manufacturer entries, a definitive named list cannot be generated.
What does the FDA label list as VECTICAL suppliers and manufacturers?
Answer: The controlling public record is the prescribing information for the VECTICAL product tied to each NDC. It lists:
- Applicant/holder (marketing authorization holder in the US context)
- Manufacturer for distribution and/or drug product manufacture
- Sometimes packaging/distribution details
Which NDCs and labelers define VECTICAL supply?
Answer: VECTICAL’s “supplier” set can change by:
- Strength (mcg per gram)
- Formulation type (ointment base)
- Package size
- Revisions to manufacturer/labeler over time
A supplier list is only complete when it is mapped to the exact NDCs currently marketed.
What contract manufacturing model does VECTICAL use?
Answer: Topical dermatology brands often use:
- In-house operations by the labeler, or
- Contract manufacturing organizations (CMOs) for drug product fill/finish and packaging
The actual model for VECTICAL must be confirmed from label/manufacturer statements for each NDC.
How can you validate VECTICAL suppliers for procurement or licensing?
Answer: Validate using:
- NDC labeler and manufacturer in the approved labeling (DailyMed and FDA product listing)
- Lot and site details on current packaging
- Drug establishment registration for listed facilities (for production confirmation)
- Quality agreements (for API and excipient sourcing)
Are there multiple manufacturers for VECTICAL across regions or time?
Answer: Yes. Even within the US, suppliers can shift with:
- Site changes
- Label revisions
- Corporate transactions
A historically correct list for “current suppliers” requires tying to today’s NDC labeler/manufacturer records.
How strong is supply continuity risk for VECTICAL?
Answer: Supply continuity risk is driven by:
- Number of qualified sterile vs non-sterile sites (VECTICAL is topical, so not sterile, but the principle still applies)
- API sourcing concentration for calcitriol
- Regulatory and manufacturing changes at facilities
A quantified risk assessment requires the manufacturer count and current facility registration, which are NDC- and record-dependent.
Key Takeaways
- “Suppliers for VECTICAL” must be defined by NDC-specific FDA labeler/manufacturer listings.
- A complete supplier map requires the exact VECTICAL NDC(s) and their corresponding labeled manufacturer chain; otherwise any named supplier list would be incomplete.
