Mechanism of Action
Levofloxacin is a broad-spectrum antibacterial agent. This enzyme acts by inhibiting DNA gyrase topoisomerase two and topoisomerase four. DNA gyrase creates a highly condensed structure of DNA that is a three-dimensional structure. By its nicking and closing activity and introducing negative supercoils to the DNA double helix. Doing levofloxacin inhibits DNA gyrase resulting in an abnormal association between open DNA and gyrase and impaired negative supercoiling. It inhibits the transcription of DNA in RNA and later protein synthesis.

Hypersensitivity to Levofloxacin and other Fluoroquinolones
Both oral and injectable fluoroquinolones are associated with side effects affecting the tendons, muscles, joints, nerves, and the central nervous system.
Fluoroquinolone is associated with inefficient and potentially irreversible serious adverse reactions that have occurred simultaneously: tendinitis and tendon rupture, peripheral neuropathy, and CNS effects
Discontinue the drug immediately and avoid the use of systemic fluoroquinolones in patients who experience any of these serious adverse reactions.
These side effects can range from a few hours to weeks after exposure to fluoroquinolones and may be permanent.
Breast Feeding: Contraindicated
The use of levofloxacin is acceptable in nursing mothers with infant monitoring for possible effects on the gastrointestinal flora, such as diarrhea or candidiasis (thrush, diaper rash). Breastfeeding should be avoided for 4 to 6 hours after a dose, which may reduce the infant’s exposure to levofloxacin.
Use with caution
