(Prussian Blue insoluble capsules) (Ferric(III)-hexacyanoferrate(II))
Hard Capsules

Heyltex Corporation is the exclusive US distributor of Radiogardase® (Prussian Blue insoluble capsules). Radiogardase® is the only FDA-approved antidote indicated for treatment of patients with known or suspected internal contamination with radioactive Cesium and/or radioactive or non‐radioactive Thallium to increase their rates of elimination. Cesium, which is found in hospital materials and construction sites, would pose a major health risk if dispersed through a “dirty bomb.”

Since the FDA approval of Radiogardase® in 2003, Heyltex has been delivering product to the Strategic National Stockpile on a regular basis.

(Trisodium zinc pentetate)
Solution for injection for intravenous injection or infusion

According to the US FDA, Calcium-based DTPA (Ca-DTPA) and Zink Trinatrium-based DTPA (Zn-DTPA) have been under investigational use for over 40 years for their ability to provide a long-term treatment for internal poisoning, be it intentional or accidental, caused by radioactive materials such as americium, plutonium and curium. In its two forms, Ca-DTPA and Zn-DTPA work by tightly binding to radioactive elements such as plutonium, americium, and curium which are then passed from the body in the urine.



Heyl SD®-1: Advanced Skin Decontamination is a breakthrough innovation in personnel and surface decontamination of a wide spectrum of chemical threat agents. SD-1 is also effective against anthrax, mycobacteria, fungal spores and viruses.

Heyl SD®-1 achieves a new level of efficacy through its ability to neutralize or degrade threat agents without water supply, mechanical preparation, or scrubbing.

HEYL SD®-1 was designed with the warfighter and military applications in mind but is equally well suited to civilian applications including use by law enforcement and emergency medical personnel.
