US Food and Drug Administration (FDA) has approved a drug to treat the deleterious effects of radiation exposure following a nuclear incident. Originally, the drug was used to treat side effects of chemotherapy.
The drug, Neupogen, is the first ever approved for the treatment of acute radiation injury and the approval came as a result of research performed by the University of Maryland School of Medicine (UM SOM) scientists, claims a study.
Chemotherapy Drugs
Chemotherapy drugs perform like 'magic bullets' to destroy cancer cells in the body.

The investigators did their research in a non-human clinical model of high-dose radiation.
"Our research shows that this drug works to increase survival by protecting blood cells. That is a significant advancement, because the drug can now be used as a safe and effective treatment for the blood cell effects of severe radiation poisoning," said Thomas MacVittie, one of the researchers.
![Chemotherapy]( "Chemotherapy")
''Chemo'' means medicine or ''drug'', ''therapy'' means ''treatment''. Chemotherapy refers to the use of cytotoxic drugs in the treatment of cancer.
Radiation damages the bone marrow, and as a result decreases production of infection-fighting white blood cells. Neupogen counteracts these effects.
The drug, which is made by Amgen Inc., was first approved in 1991 to treat cancer patients receiving chemotherapy.
Although doctors may use it "off label" for other indications, the research and the resulting approval would speed up access to and use of the drug in the event of a nuclear incident, the study noted.
The research builds on 40 years of work that MacVittie and his team have conducted in the field of radiation research, during which they have helped to define the field.
