Norfloxacin

Absorption

Rapid

Description

Norfloxacin is the first of the third generation nalidixic acid analogs to reach the marketplace. It exhibits potent in vitro and in vivo activity against Pseudomonas, enteric gram-negative rods and gram-positive cocci. Norfloxacin is orally effective in the treatment of urinary tract infections, including those due to organisms refractory to many other agents.

The Uses of Norfloxacin

It finds it application as a fluorinated quinolone antibacterial. It is clinically used to treat urinary tract infections and prostatitis. In neutrophils from cirrhotic subjects, norfloxacin increases expression of IL-10 and heme oxygenase 1 (HO-1) and decreases expression of pro-inflammatory cytokines. Additionally, when complexed with gold(III), norfloxacin binds DNA and inhibits cellular proliferation in several cancer cell lines.

What are the applications of Application

Norfloxacin is a fluorinated quinolone antibacterial agent

Indications

For the treatment of urinary tract infection

Background

A synthetic fluoroquinolone (fluoroquinolones) with broad-spectrum antibacterial activity against most gram-negative and gram-positive bacteria. Norfloxacin inhibits bacterial DNA gyrase.

Pharmacokinetics

Norfloxacin is a quinolone/fluoroquinolone antibiotic. Norfloxacin is bactericidal and its mode of action depends on blocking of bacterial DNA replication by binding itself to an enzyme called DNA gyrase, which allows the untwisting required to replicate one DNA double helix into two. Notably the drug has 100 times higher affinity for bacterial DNA gyrase than for mammalian.

Metabolism

Via liver and kidney
