Cefodizime, a new 2-aminothiazolyl cephalosporin: physicochemical properties, toxicology and structure-activity relationships.

Cefodizime is a 2-aminothiazolyl cephalosporin for parenteral use. Cefodizime has a bisubstituted thiothiazole moiety in position 3 of the cephem nucleus. The presence of this moiety does not alter the in-vitro antibacterial activity, or safety in animal studies, which are similar to those of cefotaxime, but results in an apparent long elimination half-life in rodents and dogs, and in novel immunological properties.
