摘要: Crystallized cephalosporin salts, particularly crystalline addition salt of pivaloyloxymethyl 7.beta.-[2-(2-aminothiazol-4-yl)acetamido]-3-[[[1-(2-dimethylaminoethyl)-1H-tetrazol-5-yl]thio]methyl]ceph-3-em-4-carboxylate with hydrochloric acid, tartaric acid or citric acid, which is very stable and is readily adsorbable through intestinal tract, with little individual differences, when the salt is applied orally.
