Arbekacin

(M. Kurebe et al.) Chemical name of Arbekacin is "1-N[(S)-4-amino-2-hydroxybutyl]-3',4'-dideoxykanamycin B".(Yusuke Tanigawara et al.) It is a derivative of "Dibekacin". (M. Inoue et al.)Arbekacin works good against methicillin resistant staphylococcus aureus (MRSA), which are even resistant to other types of good aminoglycosides. (M. Kurebe et al.)It is less toxic to ear than amikacin and dabekacin.

Dosage and administration:
(Yusuke Tanigawara et al.) Its usual dose for adults is 150-200 mg/day. It is administered IV or IM in divided doses.

Pharmacokinetics:

Elimination:
(Yusuke Tanigawara et al.) It is eliminated in the urine.
