[Experience with vaginal suppositories containing chemotherapeutic agents (author's transl)]

The authors determined the release of chloramphenicol, oxytetracycline, neomycin and sulphadimidine from different bases (polyoxethene mass, solid fat, 95% solid fat +5% Span 20). The diffusion of chloramphenicol and sulphadimidine was best from hydrophilic bases; that of oxytetracycline and neomycin, from emulsifier-containing lipophil bases. This may be explained by the solubilities of the pharmaca and by interactions between base and active substance.
