Pseudomonas aeruginosa infections bronchitis

Levofloxacin (1), the levo-isomer or the (5)-enantiomer of ofloxacin, received FDA approval in 1996 (Fish, 2003 Hurst et al., 2002 Mascaretti, 2003 Norrby, 1999 North et al., 1998). The initial approval covered community-acquired pneumonia, acute bacterial exacerbation of chronic bronchitis, acute maxillary sinusitis, uncomplicated skin and skin structure infections, acute pyelonephritis, and complicated urinary tract infections (North et al., 1998). Four years later, the levofloxacin indication list grew to include community-acquired pneumonia caused by penicillin-resistant Streptococcus pneumoniae. In addition, in 2002, nosocomial (hospital-acquired) pneumonia caused by methicillin-susceptible Staphylococcus aureus, Pseudomonas aeruginosa, Serratia marcescens, Haemophilus influenzae, Kliebsella pneumoniae, and Escherichia coli was added (Hurst et al., 2002). Finally in 2004, LVX was approved as a post-exposure treatment for individuals exposed to Bacillus anthracis, the microbe that causes anthrax, via inhalation (FDA, 2004). 

Lomefloxacin, a fluoroquinolone broad-spectrum antibiotic (400 mg p.o. daily for 10 to 14 days), is used in acute bacterial exacerbations of chronic bronchitis caused by Haemophilis influenzae or Moraxella (Branhamella) catarrhalis in uncomphcated urinary tract infections (cystitis) caused by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, or Staphylococcus saprophyticus, in complicated urinary tract infections caused by E. coli, K. pneumoniae, P. mirabilis, and Pseudomonas aeruginosa and it is possibly effective against infections caused by Citrobacter diversus or Enterobacter cloacae and for the prophylaxis of infections after transurethral surgical procedures (see also Figure 85).
