Amifostine is the generic name for a drug that is marketed using the name Ethyol. This medicine is supposed to protect against the damaging effects of radiation. The medicine was originally developed by the military that was working on a medicine that would protect soldiers from exposure from a radioactive “dirty” bomb. It was ultimately licensed by the pharmaceutical industry for medical uses.
The drug is supposed to be a free radical scavenger. Since radiation creates free radicals that subsequently damage DNA, a free radical scavenger would theorectically mitigate some of this effect. The drug is believed to be preferentially taken up by normal tissues instead of the tumor, which is why amifostine shouldn’t protect the tumor.
