Levofloxacin **0mg Tablets 1**0 Packing

Levofloxacin  is a broad spectrum antibiotic of the fluoroquinolone drug class. Its spectrum of activity includes most strains of bacterial pathogens responsible for respiratory, urinary tract, gastrointestinal, and abdominal infections, including Gram-(-) (Escherichia coli, Haemophilus influenzae, Klebsiella pneumoniae, Legionella pneumophila, Moraxella catarrhalis, Proteus mirabilis, and Pseudomonas aeruginosa), Gram-(+) (methicillin-sensitive but not methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae, Staphylococcus epidermidis, Enterococcus faecalis, and Streptococcus pyogenes), and atypical bacterial pathogens (Chlamydophila pneumoniae and Mycoplasma pneumoniae). Levofloxacin and other fluoroquinolones are valued for this broad spectrum of activity, excellent tissue penetration, and for their availability in both oral and intravenous formulations. (Many antibacterials used in serious infections must be dosed intravenously.) Levaquin is used alone or in combination with other antibacterial drugs to treat certain bacterial infections including pneumonia, urinary tract infections,and abdominal infections.

Levofloxacin is a chiral fluorinated carboxyquinolone. Investigation of ofloxacin, an older drug that is the racemic mixture, found that the (–)-(S) enantiomer (also known as the S isomer) is more active. This specific component is levofloxacin.
