Documented Uses

• For the treatment of bacterial infections of the respiratory tract (chronic bronchitis) and urinary tract, and as a pre-operative prophylactic to prevent urinary tract infection caused by: S.pneumoniae, H.influenzae, S.aureus, P.aeruginosa, E. cloacae, P. mirabilis, C. civersus, S. asprphyticus, E.coli, and K.pneumoniae.
• Breast Feeding; Lactation; Milk, Human; Anti-Infective Agents; Antibacterial Agents; Quinolones; Fluoroquinolones
• Avoid multivalent ions. Separate the administration polyvalent ions, including magnesium and aluminum-containing antacids, from lomefloxacin by at least 4 hours before and 2 hours after lomefloxacin dosing.
• Take with or without food. The rate and extent of absorption may be reduced when lomefloxacin is taken with food.
• Substances that inhibit the growth or reproduction of BACTERIA.
• Compounds that inhibit the activity of DNA TOPOISOMERASE II. Included in this category are a variety of ANTINEOPLASTIC AGENTS which target the eukaryotic form of topoisomerase II and ANTIBACTERIAL AGENTS which target the prokaryotic form of topoisomerase II.
