Life threatening infections (use rapidly absorbed products). Any time oral route is inappropriate (vomiting, absorption affected by Gl disease, in ruminants). |

pharmacokinetics |
Concentration profiles for IM and SC are very similar (on average) but SC is more variable. Expect less variability with rapidly absorbed products. The anatomic site influences absorption rate: M. serratus ventralis cervicis > M.biceps > M.pectoralis > M gluteus (decreasing availability – procaine pen G) |
