Introduction
Sodium iodide I-123 is a radiopharmaceutical widely used in medical imaging, particularly for thyroid and parathyroid scans. This article provides an update on the clinical trials, market analysis, and future projections for this drug.
Clinical Trials and Applications
Diagnostic Imaging
Sodium iodide I-123 is primarily used as a contrast agent in thyroid scintigraphy and parathyroid imaging. Clinical trials have demonstrated its efficacy and safety in these applications. For instance, a phase-1 clinical study on high-specific-activity carrier-free 123I-iobenguane showed promising results in terms of organ distribution, whole-body retention, and imaging efficacy[3].
Therapeutic Applications
Beyond diagnostic imaging, sodium iodide I-123 has been explored in therapeutic contexts, particularly when combined with other treatments. For example, the sodium iodide symporter (NIS) gene transfer followed by the application of 131I or alternative radiopharmaceuticals has shown significant therapeutic responses in various cancers, including prostate, head and neck, and pancreatic cancers[1].
Recent Clinical Trials
A phase 1 trial involving 123I SPECT/CT scans in patients with myeloma showed modest iodide uptake in some lesions, although not all lesions demonstrated uptake. This trial highlighted the potential but also the challenges of using sodium iodide I-123 in certain types of cancer[1].
Market Analysis
Global Market Size and Growth
The global sodium iodide injection market, which includes sodium iodide I-123, is projected to grow significantly. By 2033, the market is estimated to reach USD 390 million, exhibiting a CAGR of 3.5% during the 2021-2026 forecast period[2].
Regional Dynamics
North America and Europe currently dominate the sodium iodide injection market due to the high prevalence of thyroid-related conditions and advanced healthcare infrastructure. However, the Asia Pacific region is expected to witness significant growth driven by the rising incidence of thyroid disorders and the expanding healthcare sector in countries like China and India[2].
Market Segments
The market is segmented based on application (hospital, clinic, others) and type (sodium iodide I-131 injection, sodium iodide I-123 injection). The sodium iodide I-131 injection segment holds the largest market share due to its wide application in thyroid imaging and therapy, but the sodium iodide I-123 injection segment is gaining popularity in the diagnostic field due to its lower radiation dose and improved image quality[2].
Market Projections
Future Growth
The global sodium iodide market, including I-123 formulations, is projected to reach a valuation of USD 304 million by 2034, with a CAGR of 5.8% between 2024 and 2034. This growth is driven by increasing demand for diagnostic imaging procedures and advancements in medical technology[5].
Key Drivers
- Increasing Demand for Diagnostic Imaging: The growing need for precise diagnostic tools in hospitals and clinics is a major driver.
- Advancements in Medical Technology: New radiopharmaceuticals and imaging techniques are fueling market expansion.

Industry Players and Collaborations
Key Industry Players
Companies such as Curium Pharma, BWXT Medical Ltd., PDRadiopharma Inc., Nova-Tech, Inc., and APP Pharmaceuticals, LLC are key players in the sodium iodide injection market. These companies are driving innovation through research and development collaborations with academic and research institutions[2].
Collaborative Research
Collaborations between industry players, research institutions, and academic organizations are crucial for accelerating innovation, discovering new applications, and improving product formulations and performance[5].
Challenges and Considerations
Thyroid Blockade
The use of thyroid blockade prior to 123I-mIBG scans has been a topic of debate. Studies suggest that thyroid blockade may not be necessary due to the low amount of free radioiodine in the preparation and the short half-life of 123I-mIBG. However, prompt communication between endocrinologists and nuclear medicine specialists is essential for clinical decision-making[4].
Other Applications of Sodium Iodide
Water Treatment and Aquaculture
Sodium iodide is also used in water treatment processes for disinfection and decontamination. Additionally, it plays a role in iodine supplementation for farmed fish and crustaceans, enhancing their health and growth[5].
Innovations in Packaging and Delivery
Stability and Convenience
Innovations in packaging materials and delivery systems are enhancing the stability, shelf life, and convenience of sodium iodide products. These advancements are expected to further boost market growth[5].
