Tigecycline is the first commercially available antibiotic of the glycylcycline class, which are a new family based on tetracyclines, but with molecular modifications to evade some, but not all, tetracycline resistance mechanisms. [1] Tetracycline resistance... [2]
Its labeled indications are:[3]

Mechanism of action
The drug evades the Tet(A-E) efflux pumps[4] which account for most acquired resistance to tetracycline and minocycline in Enterobacteriaceae and Acinetobacter spp.; also the Tet(K) pumps, which occur widely in staphylococci conferring resistance to tetracycline though not minocycline or doxycycline.[2] It binds to bacterial ribosomes that have been modified by the Tet(M) protein,Cite error: Closing </ref> missing for <ref> tag
Administration
It is given intravenously, but should not be administered simultaneously, through common tubing, with amphotericin B, chlorpromazine, methylprednisolone, or voriconazole.
