What are the suppliers for VISIPAQUE 320 (io visipaque 320 mg iodine/mL)?
VISIPAQUE 320 is a branded iodinated contrast medium. The drug is supplied to the market by its marketing authorization holder and distributor(s), with manufacturing typically performed by contracted or affiliated facilities under that holder’s global supply chain.
Who is the marketing authorization holder / primary supplier?
VISIPAQUE (iohexol) brand registrations for contrast products are held by GE Healthcare entities and supplied through GE HealthCare distribution networks in multiple countries, with local wholesalers and distributors used for dispensing in-market.
How does sourcing work in practice (manufacturer vs. distributor)?
For injectable contrast media like VISIPAQUE 320, supply is usually structured in three layers:
- Marketing authorization holder (brand owner and label supplier)
- Contract or corporate manufacturing sites that produce and release iohexol and fill-finish the product
- Local distributors/wholesalers that deliver packaged product to hospitals, imaging centers, and pharmacies
What suppliers provide the underlying active ingredient and material?
VISIPAQUE 320 contains iohexol. The direct supply chain typically includes:
- Iohexol API suppliers (active ingredient)
- Halting/sterility and fill-finish suppliers (aseptic processing, container closure systems)
- Imaging-grade packaging suppliers (vials/syringes, rubber closures, seals)
- Quality testing laboratories (release testing, stability programs, sterility/endotoxin testing)
What are the packaging formats that drive the supplier network?
The supplier list depends on the presentation:
- Vials (multi-dose or single-dose depending on market)
- Prefilled syringes
- Hospital pack configurations
Each presentation changes the set of component suppliers (container closure, labels, syringe assemblies) even when the active ingredient is the same.
Where do investors and R&D teams find the legally binding supplier lists?
For pharmaceutical products, the legally binding supplier structure is typically evidenced by:
- Marketing authorization / product label (Summary of Product Characteristics)
- Regulatory dossiers and inspection records (manufacturing and testing sites)
- Local tender documents used by national hospital procurement systems
- Distribution authorization filings for import and wholesale supply
What suppliers are most likely implicated for VISIPAQUE 320?
Given the product class (injectable iodinated contrast media) and brand ownership structure, the supplier universe that matters for business decisions is:
- GE HealthCare as brand owner and primary market supplier
- Iohexol API manufacturing partners (specialty chemical manufacturers of iodinated contrast APIs)
- Aseptic fill-finish contractors or affiliated manufacturing plants
- Container closure system suppliers meeting injectable sterility standards
Key due-diligence checklist used to identify the exact named suppliers
When validating the exact named suppliers in a specific country and presentation, the supplier names should be pulled from:
- Product label “Manufactured for/By” and “Distributed by” statements
- Regulatory “Marketing authorization holder” and “Release/testing site” listings
- Hospital procurement specs listing “manufacturer and packer”
Key Takeaways
- VISIPAQUE 320 is supplied through GE HealthCare’s brand and distribution system, with manufacturing performed at contracted or affiliated fill-finish and API supply sites.
- The supplier list is presentation-specific (vial vs prefilling), because packaging and aseptic fill-finish components differ.
- The only supplier list that supports high-stakes contracting or investment diligence is the one taken from label/regulatory manufacturing and distribution statements and country-specific procurement documents.
