Description

Lomefloxacin is a fluoroquinolone antibiotic, used to treat bacterial infections including bronchitis and urinary tract infections. It is also used to prevent urinary tract infections prior to surgery.

Indication

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.

Pharmacology

Lomefloxacin is a fluoroquinolone antibiotic used to treat chronic bronchitis, as well as complicated and uncomplicated urinary tract infections. It is also used as a prophylactic or preventative treatment to prevent urinary tract infections in patients undergoing transrectal or transurethral surgical procedures. Flouroquinolones such as lomefloxacin possess excellent activity against gram-negative aerobic bacteria such as E.coli and Neisseria gonorrhoea as well as gram-positive bacteria including S. pneumoniae and Staphylococcus aureus. They also posses effective activity against shigella, salmonella, campylobacter, gonococcal organisms, and multi drug resistant pseudomonas and enterobacter.

Toxicity

Adverse reactions include peripheral neuropathy, nervousness, agitation, anxiety, and phototoxic events (rash, itching, burning) due to sunlight exposure.

Affected Organisms

Biotransformation

Minimally metabolized although 5 metabolites have been identified in human urine. 65% appears as the parent drug in urine and 9% as the glucuronide metabolite.

Absorption

Rapid and nearly complete with approximately 95% to 98% of a single oral dose being absorbed.

Half Life

8 hours

Protein Binding

10%

Elimination

The urinary excretion of lomefloxacin was virtually complete within 72 hours after cessation of dosing, with approximately 65% of the dose being recovered as parent drug and 9% as its glucuronide metabolite.
