ABSTRACT:
The present invention relates to a sterile, stable vacuum dried crystalline amifostine composition and, optionally, pharmaceutically acceptable excipient(s). Typically, the crystalline compositions of the present invention exhibit enhanced stability at temperatures ranging from about 4.degree. C. to about ambient temperature for a period of at least 2 years relative to existing solid vacuum dried amorphous amifostine preparations. The reconstituted compositions of the present invention are suitable for administration to humans as a radio- or chemoprotecting agent.
