Abstract
There is described a product which is a highly pure substantially amorphous form of cefuroxime axetil (cefuroxime 1-acetoxyethyl ester) which is stable, which has increased absorption via the gastro-intestinal tract and has a correspondingly high level of bioavailability on oral or rectal administration. Methods of preparing the product are also described which involve the recovery of the product from a solution thereof. A preferred method is the use of spray drying techniques, though roller drying, solvent precipitation or freeze-drying are also described. Also disclosed are pharmaceutical compositions containing the product and methods for its use in medicine.
