Dovramilast (CC-11050) is an orally active phosphodiesterase 4 (PDE4) inhibitor and can reduce the inflammatory response and improves Isoniazid (INH)-mediated bacillary clearance from the lungs. Dovramilast, as an adjunct, is used for the research of tuberculosis (TB) In Vivo Dovramilast (oral gavage, 5, 25, or 50 mg/kg, single) significantly improves antibiotic-mediated bacterial killing and reduces lung pathology.
