Mode of action Levofloxacin is the L-isomer of the racemate, ofloxacin, a quinolone antibiotic. The antibacterial activity of ofloxacin resides primarily in the L-isomer. The mechanism of action of levofloxacin and other fluoroquinolone antimicrobials involves the inhibition of bacterial topoisomerase IV and DNA gyrase (both of which are Type II topoisomerases), enzymes required for DNA replication, transcription, repair, and recombination. As the S (-) enantiomer of the fluoroquinolone, ofloxacin, levofloxacin, inhibits DNA-gyrase in susceptible organisms thereby inhibits relaxation of supercoiled DNA and promotes breakage of DNA strands. DNA gyrase (topoisomerase II), is an essential bacterial enzyme that maintains the superhelical structure of DNA and is required for DNA replication and transcription, DNA repair, recombination, and transposition. can i buy retin a over the counter Both ofloxacin and ciprofloxacin are fluoroquinolones with similar properties. However, antibiotics differ in their antimicrobial activity, clinical uses, pharmacokinetic and interaction profiles. Ciprofloxacin has better activity against Gram-negative bacilli. Ofloxacin has a longer half-life and higher serum levels. Ofloxacin does not significantly alter theophylline concentrations. Urinary tract infections Ciprofloxacin and ofloxacin are equally effective in women with complicated lower urinary tract infection Gonorrhea Single dose cefuroxime axetil is as effective as a single dose of ciprofloxacin in the treatment of uncomplicated gonorrhea caused by penicillinase-producing Neisseria gonorrhoeae (PPNG). However cefuroxime appears to be less effective than ciprofloxacin in treating urethral gonococcal infections in men, although both are highly effective in treating cervical gonococcal infections in women Skin infections Oral ciprofloxacin may be more effective than parenteral cefotaxime in the treatment of infections of the skin and skin structure.

Both ofloxacin and ciprofloxacin are fluoroquinolones with similar properties. However, antibiotics differ in their antimicrobial activity, clinical uses, pharmacokinetic and interaction profiles. Ciprofloxacin for Urinary Tract Infections Antibiotics are the mainstay treatment for complicated and uncomplicated urinary tract infections (UTIs). The choice of antibiotic and length of treatment depend on the patient's history and the urine tests that identify the offending bacteria. The sensitivity test is especially useful in helping select the most effective medication. Escherichia coli is the leading cause of UTIs, followed by Staphylococcus saprophyticus, Proteus spp., and Klebsiella spp. Fluoroquinolones are the standard alternatives to Sulfonamides (TMP-SMX), and sometimes are preferred antibacterials for UTI. Ciprofloxacin is very effective for the treatment of acute or complicated UTIs. This antibiotic is frequently used to treat urinary infections because of its excellent activity against majority of urinary tract pathogenic bacteria, and particularly E. In fact, ciprofloxacin urinary concentrations are 10-50 fold higher than plasma. This includes bone and joint infections, intra abdominal infections, certain type of infectious diarrhea, respiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others. Ciprofloxacin is used to treat a wide variety of infections, including infections of bones and joints, endocarditis, gastroenteritis, malignant otitis externa, respiratory tract infections, cellulitis, urinary tract infections, prostatitis, anthrax, and chancroid. Ciprofloxacin only treats bacterial infections; it does not treat viral infections such as the common cold. For certain uses including acute sinusitis, lower respiratory tract infections and uncomplicated gonorrhea, ciprofloxacin is not considered a first-line agent. Ciprofloxacin occupies an important role in treatment guidelines issued by major medical societies for the treatment of serious infections, especially those likely to be caused by Gram-negative bacteria, including Pseudomonas aeruginosa. For example, ciprofloxacin in combination with metronidazole is one of several first-line antibiotic regimens recommended by the Infectious Diseases Society of America for the treatment of community-acquired abdominal infections in adults. In other cases, treatment guidelines are more restrictive, recommending in most cases that older, narrower-spectrum drugs be used as first-line therapy for less severe infections to minimize fluoroquinolone-resistance development.
