The present research is related to all degradation studies including  acidic, alkaline, thermal and photo stability on the drug substance according to International Conference on Harmonization  ICH  guidelines. In this study, the degradation profiles of macrolide antibiotics “roxithromycin  ROX , tilmicosin  TIL  and tylosin  TYL ”  under varied stress conditions were investigated. The behavior of these drugs under hydrolytic, oxidative, thermal and photolytic conditions were determined by high performance  liquid chromatography  HPLC .</p></abstract>
