BookPublisher: 2012Subject(s): Department of Pharmaoclogy & ToxicologyDDC classification: 1468,T Dissertation note: This project was designed to study the chemical equivalence of various brands of Oxytetracycline hydrochloride (long acting, short acting & PVP) approved by the ministry of health and available in the local market for veterinary use. Oxytetracycline was measured by HPLC method developed and standardized in the laboratory. Limit of detection (LOD) and limit of quantification (LOQ) of the Oxytetracycline by HPLC assay method were determined. From stock solution of working standard (Oxytetracycline hydrochloride) different concentrations 0.05, 0.1, 0.5, 1.0, 10, 25, 50 and 100µg per ml were prepared for the determination of LOD. The LOD calculated was 0.100(µg/ml) and LOQ was 0.5 (µg/ml). Correlation coefficient was 0.99994050. Concentration of the active ingredient (Oxytetracycline hydrochloride) in all preparations was same as mentioned on the label except Oxytetracycline (74%), Terrasym PVP-100 (81%), and Onyx-LA (72%).
MIC of Oxytetracycline hydrochloride against following bacterial isolates determined by micro-broth dilution test was Bacillus subtilis (50µg), Staphylococcus aureus (100µg), Eschericiha coli (50µg), Salmonella enterica (1000µg) and Pasturella multocida (50µg).It showed that all these bacterial cultures have developed resistance against Oxytetracycline hydrochloride.
