Ketek is an antibiotic drug approved to treat mild to moderate community-acquired pneumonia. Community-acquired pneumonia (CAP) is a type of pneumonia (inflammation of the lung) contracted by patients not confined in a health institution or has been confined for only a few days. CAP is a very common health problem, and it is the leading cause of death. CAP can be caused by viruses, bacteria, fungi or parasites.
Doctors prescribe Telithromycin to treat CAP caused by the bacteria Streptococcus pneumoniae (including multidrug-resistant isolates), Haemophilus influenzae, Moraxella catarrhalis, Chlamydophila (also known as Chlamydia) pneumoniae, or Mycoplasma pneumonia.
