Absorption GI absorption is poor. Any obstructions or factors which impair GI motility may increase the absorption of the drug from the digestive tract. In addition, any structural damage, such as lesions or ulcerations, will tend to increase drug absorption. For intramuscular (IM) injection, the absorption is rapid.<unk>  will reach peak plasma concentration within one hour following IM injection. The in-vitro and in-vivo activities parallel those of neomycin. Distribution Information not available. Elimination Almost 100% of the oral dose is eliminated unchanged via feces.
