What is “VOLTAREN ARTHRITIS PAIN” in patent-and-supply terms?
“VOLTAREN ARTHRITIS PAIN” is the consumer brand name used by GSK for diclofenac sodium topical products, most commonly marketed as diclofenac sodium 1% gel (US OTC and international equivalents), with the same core API: diclofenac sodium.
From a supplier perspective, the supply chain splits into:
- API supply: diclofenac sodium (manufactured to API specifications)
- Finished-dose product (FDP) supply: gel formulation, packaging, and release
- Packaging and distribution: tubes, cartons, labeling, and channel distribution
Who are the key suppliers?
Public-facing branding and listing data for diclofenac topical products points to the following supplier categories, with GSK as brand owner/marketer and API and contract manufacturing executed by upstream and toll/CMO partners.
Because your request is specifically “Suppliers for the pharmaceutical drug,” the actionable structure is the supplier map below: brand owner, API source type, and finished-dose manufacturing source type.

How does the supply chain work for diclofenac topical (practically)?
For diclofenac sodium 1% gel, supply typically follows a modular workflow:
- API procurement
- Diclofenac sodium is manufactured under GMP and supplied as API with analytical documentation.
- Formulation development and tech transfer
- Gel excipients (carbomer/gelling system, solvents, stabilizers, permeation enhancers where applicable) are mixed with diclofenac sodium to meet specification and release criteria.
- Finished-dose manufacturing
- Bulk gel is produced, filtered/deaerated as required, filled into tubes, labeled, and packaged.
- Batch release
- Quality control confirms assay, impurities, viscosity/rheology, uniformity, and microbial limits.
- Regulatory/quality oversight
- Brand owner controls release disposition through quality agreements and vendor qualification.
What can be stated with confidence from public regulatory and brand structure?
Brand ownership and marketed product
- VOLTAREN is marketed globally by GSK (brand owner/marketer for many diclofenac products). This is the entity behind the consumer-facing product line.
- “VOLTAREN ARTHRITIS PAIN” corresponds to topical diclofenac sodium formulations, most frequently 1% gel in OTC contexts.
API and CMO sourcing
- API is supplied by API manufacturers (or toll API suppliers) and CMO partners produce the finished gel. These sources vary by geography and contract year; the binding facts are the product composition (diclofenac sodium topical) and the brand owner (GSK), not a single universal supplier name for every market.
What is the core API and therefore the core supplier responsibility?
Active ingredient
The supplier responsibility for diclofenac sodium is to provide:
- GMP-compliant API
- Traceable CoA
- Impurity profile and stability support consistent with topical diclofenac sodium requirements
Market variants can change the manufacturing site, not the API
Even with the same “VOLTAREN ARTHRITIS PAIN” naming, finished-dose supply can shift due to:
- local regulatory requirements
- commercial manufacturing capacity allocations
- distribution footprint
The API stays diclofenac sodium; the finished-dose manufacturing and packaging vendors can change by region.
Key Takeaways
- VOLTAREN ARTHRITIS PAIN is a topical diclofenac sodium product, typically supplied as diclofenac sodium 1% gel.
- GSK is the brand owner/marketer for VOLTAREN in many markets.
- Supplier sourcing is structurally split into API suppliers (diclofenac sodium) and finished-dose manufacturers/packagers (1% diclofenac sodium gel and tubes).
- There is no single universal named supplier for all locations and batch cycles; the supply chain is governed by qualified API and CMO vendors under GSK quality oversight.
