Introduction: Addressing the Core User Need – From Limited ARS Treatment Options (Supportive Care, Bone Marrow Transplant) to Radioprotective (Amifostine), Radionuclide Decorporation (Prussian Blue (Cesium-137, Thallium), DTPA (Plutonium, Americium, Curium)), Thyroid Blocking (Potassium Iodide (KI) for Radioactive Iodine (I-131)), and Cytokine (Filgrastim (G-CSF) for Neutropenia, Thrombocytopenia) Therapies for Mass Casualty Management Following Nuclear Reactor Meltdowns (Chernobyl (1986), Fukushima (2011)), Dirty Bombs (Radiological Dispersal Devices, RDD), Nuclear Detonations, and Occupational Exposure (Nuclear Power Plant Workers, Medical Radiation Accidents)
Nuclear radiation refers to the various microscopic particles (alpha (α), beta (β), neutron (n)) and electromagnetic radiation (gamma (γ), X-ray) or energy released during nuclear reactions such as fission and decay of atomic nuclei. This radioactive material exists in large quantities in nuclear explosions (atomic bomb, hydrogen bomb), nuclear leakage accidents (Chernobyl (1986, iodine-131, cesium-137, strontium-90), Fukushima Daiichi (2011, iodine-131, cesium-134, cesium-137, strontium-90)), and nuclear waste (spent fuel reprocessing, nuclear fuel cycle). Anti-nuclear radiation drugs commonly used in clinical practice include thiol drugs (amifostine (Ethyol) – radioprotector, scavenges free radicals, DNA repair), cytokine drugs (filgrastim (G-CSF), pegfilgrastim (Neulasta), sargramostim (GM-CSF) – accelerates neutrophil recovery, reduces neutropenia duration), hormone drugs (potassium iodide (KI), potassium iodate (KIO₃) – thyroid blocking, prevents radioactive iodine (I-131) uptake), metal complexing agents (Prussian blue (potassium ferric hexacyanoferrate) – decorporation of cesium-137 (Cs-137), thallium (Tl); diethylenetriamine pentaacetate (DTPA, Ca-DTPA, Zn-DTPA) – decorporation of plutonium (Pu-238, Pu-239, Pu-240), americium (Am-241), curium (Cm-242, Cm-244)), and Chinese herbal medicines (research stage). The development prospect of anti-nuclear radiation medicine depends to a large extent on the development trend of global nuclear energy. If global nuclear power generation continues to increase (2025 global nuclear capacity 420GW, 10% of electricity generation, IAEA), market demand for nuclear radiation protection drugs may increase accordingly (stockpiling, emergency preparedness). At present, the global anti-nuclear radiation drug market has been researched and developed by some major pharmaceutical companies and biotechnology companies (Amgen (filgrastim, Neupogen), Bayer (Prussian blue (Radiogardase)), GSK (amifostine (Ethyol)), Pfizer (DTPA (Zinc-DTPA, Calcium-DTPA)), Novartis, Teva, Sun, Merck). The main types of anti-nuclear radiation drugs include stable iodine (potassium iodide (KI), potassium iodate (KIO₃)), Prussian blue (Radiogardase), zinc/calcium lozenges (DTPA, Ca-DTPA, Zn-DTPA), complement activators (research), antibiotics (infection prophylaxis in neutropenic patients), anti-radiation drugs (amifostine), etc. Among them, stable iodine (KI) and Prussian blue are the most commonly used drugs for the prevention and treatment of acute radiation exposure (thyroid blocking, cesium/thallium decorporation). Although the market size of nuclear radiation protection drugs is relatively small (US1.1Bin2025,projectedUS1.1Bin2025,projectedUS 1.8B in 2032, 9.5% CAGR), it is expected to maintain rapid growth in coming years. This is primarily attributable to heightened concern over nuclear radiation incidents (Fukushima wastewater release (2023-2024, ALPS treated water, tritium), Ukraine Zaporizhzhia nuclear plant shelling (2022-2023, IAEA monitoring), North Korea nuclear tests (2006-2017, 6 tests), Iran nuclear program (uranium enrichment, Natanz, Fordow), China nuclear expansion (20 new reactors by 2030)) and increased need for prevention and treatment of radiation exposure. However, the development and application of anti-nuclear radiation drugs still face some challenges. For example, anti-nuclear radiation drugs currently on the market are mainly aimed at a specific type or dose of radiation (acute (high dose, short duration) vs chronic (low dose, long duration) exposure), rather than being widely applicable. In addition, due to the rarity of nuclear radiation incidents, there are certain difficulties in clinical trials (randomized controlled trials, RCTs, ethical issues, lack of exposed patients) and applications (stockpiling, shelf life, distribution logistics) of these drugs. In general, the development prospects of anti-nuclear radiation drugs seem bright, but continued in-depth research and development (novel radioprotectors (Ex-Rad, BIO 300, CBLB502), decorporation agents (HOE-9, FBC-321)), stockpiling (SNS (Strategic National Stockpile), EU RescEU, Japan Nuclear Emergency Preparedness, China Strategic Reserve), and regulatory approval (FDA Animal Rule (for biodefense, radiation countermeasures, accelerated approval), EMA PRIME (PRIority MEdicines)) are needed to overcome existing technical and market challenges.

5. Risk note
Anti-nuclear radiation drugs have limited efficacy for high-dose radiation exposure (>8 Gy, LD100 (lethal dose 100%)) – bone marrow failure (pancytopenia), gastrointestinal (GI) syndrome (nausea, vomiting, diarrhea, dehydration, electrolyte imbalance, GI bleeding, sepsis), cardiovascular collapse, multi-organ failure. Supportive care (blood transfusion (RBC, platelets, FFP), antibiotics (prophylaxis, neutropenic fever), IV fluids (normal saline, Ringer’s lactate), electrolyte replacement (K, Mg, Ca, PO₄), antiemetics (ondansetron, metoclopramide), antidiarrheals (loperamide, atropine/diphenoxylate), pain management (morphine, hydromorphone), burn care (radiation dermatitis, mucositis), psychological support) may be required. Additionally, adverse effects: potassium iodide (KI) – GI upset (10-20%), rash (5-10%), salivary gland swelling (sialadenitis, 5-10%), metallic taste (2-5%), allergic reaction (iodism, 1-2%). Prussian blue – constipation (10-20%), blue discoloration of stool (2-5%). DTPA – nausea (5-10%), vomiting (5-10%), diarrhea (5-10%), headache (5-10%), fever (2-5%), rash (2-5%), thrombophlebitis (1-2%). Filgrastim (G-CSF) – bone pain (20-30%, medullary cavity expansion), splenomegaly (2-5%), splenic rupture (rare, <0.1%). Amifostine – hypotension (15-20%, IV infusion over 15 minutes, hydration (500mL normal saline pre-infusion)), nausea, vomiting (10-15%, antiemetic (ondansetron, granisetron, dolasetron, palonosetron) pre-medication). Finally, shelf life – stockpiled drugs (KI, Prussian blue, DTPA, filgrastim, amifostine) expire (2-5 years). Rotate stock (FEFO first-expired-first-out), test potency (accelerated stability study, 40°C/75% RH, 6 months), replace expired units.
