| Description | Norfloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria, which functions by inhibiting DNA gyrase.
Target: DNA gyrase; Antibacterial
Norfloxacin is a synthetic chemotherapeutic antibacterial agent occasionally used to treat common as well as complicated urinary tract infections. Norfloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV, enzymes necessary to separate bacterial DNA, thereby inhibiting cell division.There are currently three approved uses in the adult population (one of which is restricted) and the other ineffective due to bacterial resistance. Chibroxin (ophthalmic) is approved for use in children older than one year of age.
Norfloxacin is associated with a number of rare serious adverse reactions as well as spontaneous tendon ruptures and irreversible peripheral neuropathy. Tendon problems may manifest long after therapy had been completed and in severe cases may result in lifelong disabilities. Hepatoxicity resulting in fatalities has also been reported with the use of norfloxacin. References: | |||||

Preparation of biochar by simultaneous carbonization, magnetization and activation for norfloxacin removal in water.[Pubmed:28279909]
Bioresour Technol. 2017 Jun;233:159-165.
Activated magnetic biochar (AMB) was prepared with corn stalks, reed stalks, and willow branches by simultaneous carbonization, magnetization, and activation, and used for Norfloxacin removal in water. The exploration results showed that the zeta potential was positively charged at pH 2-10. These prepared activated magnetic biochars have a large specific surface area (>700m(2).g(-1)) and pore volume (>0.3cm(3).g(-1)). The quasi-second-order kinetic adsorption equation could better describe the adsorption of NOR on AMB. The Langmuir isotherm showed the better fitting results on AMB. The AMB showed the strong adsorption of NOR, and the saturated adsorption capacity of corn activated magnetic biochar was the highest, 7.6249mg.g(-1). The adsorption of NOR on AMB was a spontaneous endothermic process. The effect of pH on the adsorption behaviors of NOR on AMB was not obvious, and AMB had a good adsorption effect on NOR in a wide pH range.
Development and Validation of a Green Analytical Method for the Determination of Norfloxacin in Raw Material by FTIR Spectrophotometry.[Pubmed:28206879]
J AOAC Int. 2016 Nov 1;99(6):1533-1536.
Norfloxacin is a broad-spectrum antimicrobial agent, widely used in humans and animals for the treatment of urinary tract infections. It is a second-generation fluoroquinolone. Several analytical methods to analyze Norfloxacin have been described in the literature. However, most of them are complex and require the use of large amounts of organic solvents. This paper describes the development and validation of a green analytical method for the determination of Norfloxacin in raw material by FTIR spectrophotometry. This method does not require the use of organic solvents, minimizing waste generation in the process and its environmental impacts. The development of methods that promote the reduction, prevention, or elimination of waste generation has become highly attractive to the pharmaceutical industry because of the growing demand from civil society and government authorities for environmentally friendly products and services. The FTIR spectrophotometry method was validated according to International Conference on Harmonization guidelines, showing adequate linearity (r = 0.9936), precision, accuracy, and robustness. This validated method can be used as an environmentally friendly alternative for the quantification of Norfloxacin in raw material in QC routine analysis.
Pharmacokinetic changes of norfloxacin based on expression of MRP2 after acute exposure to high altitude at 4300m.[Pubmed:28292016]
Biomed Pharmacother. 2017 May;89:1078-1085.
BACKGROUND: This study was to investigate the influence of physiological changes and the expression of MRP2 efflux transporter on the pharmacokinetics of Norfloxacin after acute exposure to high altitude 4300m. METHODS AND RESULTS: The rats were randomly divided into high altitude group and plain group. Blood gas and biochemical analysis showed that the physiological parameters significantly changed at high altitude. The mRNA and protein expression of MRP2 in high altitude group were higher than plain group in rat small intestine and kidney, while was reduced in rat liver. The AUC, Ka and Cmax of Norfloxacin were significantly reduced in high altitude group (p<0.05). However, the MRT, CL, t1/2 and Vd were significantly increased (p<0.05). CONCLUSIONS: These results indicate that physiological indicators and expression levels of drug transporters MRP2 are changed in responded to high altitude, to severely affect Norfloxacin pharmacokinetics. These changes may provide basis and new ideas to adjust the dosage and administration, so as to promote rational drug use in the high altitude.
Metronidazole and Norfloxacin induced Generalized Fixed Drug Eruptions in an adult male patient - A Case Report.[Pubmed:28183241]
Curr Drug Saf. 2017 Feb 9. pii: CDS-EPUB-81652.
INTRODUCTION: Fluoroquinolones are most widely used for empirical treatment of gastrointestinal disease due to emergence of drug resistant strains to other antimicrobials. They are also indulged in cutaneous adverse drug reactions with varying form of severity. CASE PRESENTATION: A 43 year old male patient developed fixed drug eruptions after administration of tablet Norfloxacin and metronidazole for treatment of colicky abdominal pain with diarrhoea. Erythematous rashes involved whole body including buccal mucosa. Causative drugs were stopped and patient was managed by local as well as systemic therapy and was recovered after 20 days. CONCLUSION: Awareness among healthcare professionals regarding FDEs and its management is essential to prevent mortality and morbidity and counsel patient regarding future use of drugs causing reactions with physician's advice.
