ABSTRACT:
The present invention relates to a sterile, stable dosage forms suitable for reconstitution and parenteral administration to a patient, said dosage form comprising an amorphous aminoalkyl dihydrogen phosphorothioate, and of amifostine in particular. The invention further relates to a method of preparing such a dosage form, which typically exhibits enhanced thermal stability as compared to existing vacuum dried amorphous amifostine.
