Who Supplies CELESTONE SOLUSPAN (Betamethasone Acetate and Betamethasone Sodium Phosphate)?
CELESTONE SOLUSPAN is a branded corticosteroid combination injectable containing betamethasone acetate (microcrystalline) and betamethasone sodium phosphate (soluble). It is manufactured and distributed by Merck & Co., Inc. (U.S. labelholder for “Celestone” brands) under NDC 0009-0xxx lines. Distribution in the U.S. typically runs through Merck distribution channels; in other jurisdictions, supply is handled via local Merck affiliates and contract partners tied to branded product distribution.
Who is the labelholder/manufacturer of CELESTONE SOLUSPAN?
- Merck & Co., Inc.
- Brand: Celestone Soluspan
- Drug substance system: betamethasone acetate + betamethasone sodium phosphate
- Responsible party on U.S. labeling for the marketed product: Merck & Co., Inc. (or its U.S. operating entity referenced on the label)
Who supplies the active pharmaceutical ingredients (APIs)?
Public, source-level supply attribution for specific API plants (site-by-site) is not consistently disclosed in the product label, and firm supplier lists are typically protected under confidentiality, sourcing agreements, and non-public manufacturing disclosures. As a result, the only reliably assignable “supplier” in a compliance-ready way is the labelholder/manufacturer for the finished dosage form, not the named upstream API vendors.

What suppliers can be listed with defensible authority?
Defensible supplier (finished product / brand owner)
- Merck & Co., Inc.
- This is the correct “supplier” to cite when the requirement is a named party tied to the marketed branded injectable.
Non-defensible supplier (API site vendors)
- Upstream API manufacturers for betamethasone acetate and betamethasone sodium phosphate are generally not named in product labeling for branded corticosteroid injectables, and public patent and regulatory disclosures do not provide a consistent, site-specific roster suitable for a definitive supplier list.
CELESTONE SOLUSPAN market supply identifiers used to trace the branded product
The most direct way to validate supplier responsibility for the finished product is through U.S. label and NDC tracing on the specific dosage form:
- Product name on label: Celestone Soluspan
- Drug content: betamethasone acetate + betamethasone sodium phosphate
- Regulatory identity: NDC under Merck labelholder branding
- Regulatory category: corticosteroid injectable
(These identifiers are used by wholesalers, distributors, and channel partners to ensure they are handling the exact branded formulation under the Merck labelholder.)
Key Takeaways
- Merck & Co., Inc. is the defensible named supplier/labelholder for CELESTONE SOLUSPAN as marketed in the U.S.
- Upstream API supplier identity (specific plants/vendors for betamethasone acetate and betamethasone sodium phosphate) is not reliably public in a way that supports a definitive supplier list.
- For procurement, distribution, or regulatory documentation requiring named responsibility, the operative party is Merck tied to the branded NDC/labeled product.
