    • Chemical Class:

      Tetracycline in which the 5<stereo>beta</stereo>-hydrogen is replaced by a hydroxy group, while the 6<stereo>alpha</stereo>-hydroxy group is replaced by hydrogen. A semi-synthetic tetracycline antibio tic, it is used to inhibit bacterial protein synthesis and treat non-gonococcal urethritis and cervicitis, exacerbations of bronchitis in patients with chronic obstructive pulmonary disease (COPD), an d adult periodontitis.
