Norfloxacine Biogaran (Norfloxacin)

Norfloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, and repair. By blocking these targets, the drug prevents the supercoiling and resealing of DNA strands, leading to accumulation of DNA breaks and ultimately bacterial cell death. This mechanism provides concentration‑dependent bactericidal activity against a range of Gram‑negative and some Gram‑positive organisms.

The specific dose and treatment duration are determined by the prescribing clinician based on the infection type, severity, patient age, renal function, and local resistance patterns. Norfloxacin is typically prescribed as an oral regimen for adults, but exact dosing instructions must be obtained from a qualified healthcare professional.

Safety data for norfloxacin during pregnancy and lactation are limited. The drug is generally avoided unless the potential benefit to the mother outweighs the possible risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternative therapies with their healthcare provider.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, and will request verification of trade or institutional credentials. After confirmation, the team provides pricing, availability, shipping details (including any cold‑chain requirements), and assists with import documentation.

Norfloxacin shares the class‑wide mechanism of DNA gyrase inhibition with other fluoroquinolones such as ciprofloxacin and levofloxacin. Compared with ciprofloxacin, norfloxacin has a similar spectrum against many Gram‑negative pathogens but may have slightly lower activity against Pseudomonas aeruginosa. Choice of agent often depends on local susceptibility patterns, patient tolerance, and specific infection site.

Store the product at room temperature, below 25 °C, in its original packaging. Protect it from moisture, excessive heat, and direct sunlight. Keep the container tightly closed and out of reach of children. No special refrigeration is required for this oral formulation.

Norfloxacine Biogaran is administered orally, usually with a full glass of water. It may be taken with or without food, but if antacids or mineral supplements are required, they should be spaced at least two hours apart to avoid reduced absorption. Patients should follow the prescribing clinician’s instructions regarding timing and duration.

The most serious adverse events include tendon rupture or tendinitis, especially in older adults or those on corticosteroids; peripheral neuropathy; QT interval prolongation leading to cardiac arrhythmias; severe allergic reactions such as anaphylaxis; and Clostridioides difficile‑associated colitis. Prompt medical attention is required if any of these symptoms develop.

Patients with a known hypersensitivity to norfloxacin, other fluoroquinolones, or any component of the formulation should avoid the drug. It is also contraindicated in pregnant or nursing women unless no safer alternative exists, and it should be used with caution in children, the elderly, and individuals with a history of tendon disorders or cardiac arrhythmias.
