The combination of meropenem (above structure)  with clavulanate (right structure-potassium salt)  has high antimycobacterial  activity in vitro against extensively drug-resistant Mycobacterium  tuberculosis strains. Researchers report the successful use of this combination  in association with linezolid (below structure)  in the management of an advanced  extensively drug-resistant tuberculosis disease with complex second-line  drug resistance in a 14-year-old teenager.
