Abstract: The pharmacokinetics of tylosin after intramuscular administration at a dose of 1g kg-1 body weight was studied in eleven healthy desert sheep. A peak level of tylosin Cmax of 198�0.95 �g mL 1 was achieved after tmax of 0,9�0.13 h and the mean distribution half-life (t1/2 ) was 2�0.3 h and the apparent elimination half-life (t1/2 ) was 72.2�9.3 h. The volume of distribution (Vd) was found to be 53.299�3.907 L. The area under the curve (AUC�240) of tylosin was calculated as being 1947.8�177.8 �g mL 1 and the Area Under Maximum Concentration Curve (AUMC) was 74285.4�5420.75 �g/mL/h2. The total clearance (cl ) was 511.7�207 �l h 1 and the mean resident time was 30±9.83 h.
