Apramycin is an aminocyclitol antibiotic with a chemical structure very similar to that of the aminoglycosides but different enough to leave it unaffected by many aminoglycoside inactivating enzymes. Apramycin is active against Staphylococcus aureus, many gram-negative bacteria, and some mycoplasma strains.
Absorption: Apramycin is rapidly and well absorbed from intramuscular (IM) and subcutaneous (SC) routes of administration. It is poorly absorbed from oral administration in adult birds.
