Treatment of Staphylococcus aureus endocarditis using moxifloxacin.

The conventional treatment of staphylococcal endocarditis requires in-patient administration, is inconvenient, and is potentially toxic. Increasing experience with well-absorbed, well-tolerated and highly active agents such as the new quinolones has prompted interest in their use as therapeutic alternatives for the treatment of such infections. We describe a case of staphylococcal endocarditis which failed to respond to conventional therapy, but where the addition of moxifloxacin, an 8-methoxyquinolone, was curative.
