Zenflox 400 Tablet contains Ofloxacin 400 mg, a broad-spectrum fluoroquinolone antibiotic used to treat a variety of bacterial infections. It is effective against both Gram-positive and Gram-negative bacteria by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination. Zenflox 400 is indicated for the treatment of respiratory tract infections, urinary tract infections, skin and soft tissue infections, prostatitis, and certain sexually transmitted infections caused by susceptible organisms. The tablet is administered orally, with dosage and duration determined by the severity and type of infection, as well as patient-specific factors such as renal function. Common side effects may include gastrointestinal disturbances like nausea, vomiting, diarrhea, and abdominal discomfort, as well as central nervous system effects such as dizziness and headache. Caution is advised in patients with a history of tendon disorders related to fluoroquinolone use, and it is contraindicated in individuals with known hypersensitivity to ofloxacin or other quinolones. Use during pregnancy and lactation should be avoided unless clearly necessary. Patients are advised to complete the full prescribed course to prevent resistance development and ensure eradication of the infection.
