Introduction
Technetium Tc-99m exametazime kit, also known as Hexamethylpropyleneamine oxime (HMPAO) kit, facilitates the preparation of Tc-99m labeled exametazime for cerebral and other organ imaging in nuclear medicine. As a critical diagnostic tool, its availability hinges on a reliable supply chain involving manufacturers that produce radiopharmaceutical kits compliant with stringent regulatory standards. This article provides an in-depth overview of current suppliers worldwide, focusing on manufacturing capabilities, market presence, and future supply considerations to aid healthcare providers, distributors, and stakeholders in strategic procurement planning.
Understanding the Technical and Regulatory Landscape
The Tc-99m exametazime kit's core function is to label the HMPAO compound with technetium-99m, a widely used radioisotope with a 6-hour half-life. The process requires specialized manufacturing facilities adhering to Good Manufacturing Practice (GMP) standards, and suppliers must secure approvals from regulatory authorities like the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), or equivalent bodies.
Key considerations for procurement include:
- Manufacturing accreditation and compliance
- Supply chain reliability
- Market reach and scalability
- Regulatory approvals for various territories
Major Suppliers of Tc-99m Exametazime Kits

Note: Their global distribution network is expanding to serve non-Indian markets more effectively.
4. Other Regional Manufacturers
Multiple regional players, primarily in Europe and Asia, manufacture Tc-99m exametazime kits under licensing agreements or through proprietary formulations. These include:
- Eckert & Ziegler (Germany): Provides radiopharmaceuticals and kits with regional distribution.
- Lantheus Medical Imaging (USA): Known for a range of radiopharmaceuticals, occasionally supplies exametazime kits through collaborations.
Market Dynamics: Regional manufacturers often hold a strong position within their territories, but limited international distribution capacity makes diversification advisable for global healthcare systems.
Emerging Suppliers and Supply Chain Challenges
Market consolidation, manufacturing bottlenecks, and the increasing demand for nuclear imaging agents have put pressure on the supply chain. Notable factors include:
- Shortage of molybdenum-99, the parent isotope for Tc-99m, affecting overall radiopharmaceutical availability.
- Regulatory hurdles imposing delays in approving new manufacturing facilities.
- Cold chain logistics complexities due to the short half-life of Tc-99m affecting distribution.
Emerging players and SMEs are investing in new GMP-compliant facilities, aiming to mitigate shortages and diversify supply.
Supply Security and Procurement Strategies
Healthcare organizations should consider multi-supplier sourcing, inventory buffering, and engaging with licensed distributors of radiopharmaceutical kits to manage supply risks effectively. Continuous monitoring of the regulatory landscape and evolving manufacturer capacities remains essential.
Regulatory Considerations
Suppliers must maintain active regulatory approvals in target markets. Changes in licensing status or manufacturing compliance can disrupt supply chains. Due diligence and supplier qualification processes should include:
- Validation of GMP compliance
- Confirmation of recent regulatory approvals
- Assessment of distribution capabilities
Conclusion
The primary supplier of Tc-99m exametazime kits is Jubilant Radiopharma (DraxImage), with increasingly regional manufacturers supplementing supply. Market shifts, regulatory dynamics, and supply chain constraints necessitate strategic sourcing and diversified procurement approaches. Stakeholders should prioritize suppliers with proven regulatory compliance, production scalability, and reliable distribution channels to ensure uninterrupted diagnostic capabilities.
