Abstract

A process for the preparation of hypoallergenic hetacycline or a non-toxic salt thereof, which method consists of subjecting a commercial form of hetacilin or a non-toxic salt thereof to at least one purification process based on differences in molecular weight or of dimensions, either during the manufacture of the hetacycline or after, to separate therefrom the antigen material of at least 1000 molecular weight, inherently present in the hetacycline.
