Ofloxacin is a synthetic 4-fluoroquinolone antibacterial agent with bactericidal activity against a wide range of Gram-negative and Gram-positive organisms. It is indicated for the treatment of the following infections when caused by sensitive organisms: Lower Respiratory Tract: Acute and chronic infections. Upper and Lower Urinary Tract: Acute and chronic lower urinary tract infections; acute and chronic upper urinary tract infections (pyelonephritis). Septicaemia. Skin and soft tissue infections. Microbiological results indicate that the following pathogens may be regarded as sensitive: Staphylococcus aureus (including methicillin resistant staphylococci), Staphylococcus epidermidis, Neisseria species, Escherichia coli, Citrobacter, Klebsiella, Enterobacter, Hafnia, Proteus (indole-negative and indole-positive strains), Salmonella, Shigella, Acinetobacter, Yersinia enterocolitica, Campylobacter jejuni, Aeromonas, Plesiomonas, Vibrio cholerae, Vibrio parahaemolyticus, Haemophilus influenzae, Chlamydiae, Legionella, Gardenerella. Variable sensitivity is shown by Streptococci, Serratia marcescens, Pseudomonas aeruginosa, Clostridium species and Mycoplasmas. Anaerobic bacteria (e.g. Fusobacterium species, Bacteroides species, Eubacterium species, Peptococci, Peptostreptococci) are normally resistant.
