Description
A synthetic fluoroquinolone (fluoroquinolones) antibacterial agent that inhibits the supercoiling activity of bacterial DNA gyrase, halting DNA replication. PubChem (source: Drug Bank)
Indication
For the treatment of bacterial conjunctivitis caused by susceptible strains of the following organisms: <i>Corynebacterium</i> species, <i>Staphylococus aureus</i>, <i>Staphylococcus epidermidis</i>, <i>Streptococcus pneumoniae</i>, <i>Streptococcus</i> (Groups C/F/G), Viridans group streptococci, <i>Acinetobacter lwoffii</i>, <i>Haemophilus influenzae</i>, <i>Serratia marcescens</i>. (source: Drug Bank)
ATC Therapeutic Categories
- J01MA:Fluoroquinolones
- S01AX:Other antiinfectives
Pharmacology, Interactions, and Contraindications
Mechanism Of Action
Levofloxacin inhibits bacterial type II topoisomerases, topoisomerase IV and DNA gyrase. Levofloxacin, like other fluoroquinolones, inhibits the A subunits of DNA gyrase, two subunits encoded by the gyrA gene. This results in strand breakage on a bacterial chromosome, supercoiling, and resealing; DNA replication and transcription is inhibited. (source: Drug Bank)
Pharmacology
Levofloxacin, a fluoroquinolone antiinfective, is the optically active L-isomer of ofloxacin. Levofloxacin is used to treat bacterial conjunctivitis, sinusitis, chronic bronchitis, community-acquired pneumonia and pneumonia caused by penicillin-resistant strains of <i>Streptococcus pneumoniae</i>, skin and skin structure infections, complicated urinary tract infections and acute pyelonephritis.

Food Interactions
Take without regard to meals. Take with water, drink lliberally. Taking this product with orange juice can result in reduced quinolone plasma levels. (source: Drug Bank)
Absorption, Distribution, Metabolism, Elimination & Toxicity
Protein Binding
24-38% (to plasma proteins) (source: Drug Bank)
Absorption
Absorption of ofloxacin after single or multiple doses of 200 to 400 mg is predictable, and the amount of drug absorbed increases proportionately with the dose. (source: Drug Bank)
Toxicity
Side effects include disorientation, dizziness, drowsiness, hot and cold flashes, nausea, slurring of speech, swelling and numbness in the face (source: Drug Bank)
Isomeric SMILES Code:
C[C@H]1COC2=C3N1C=C(C(=O)C3=CC(=C2N4CCN(CC4)C)F)C(=O)O (source: Drug Bank)
