Zanocin 200 Tablet contains Ofloxacin 200mg, a broad-spectrum fluoroquinolone antibiotic effective against a wide range of Gram-positive and Gram-negative bacterial infections. It acts by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination, thereby preventing bacterial cell division and leading to cell death. Zanocin 200 is indicated for the treatment of respiratory tract infections, urinary tract infections, skin and soft tissue infections, gastrointestinal infections, and 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 age and renal function. Common side effects may include gastrointestinal disturbances, headache, dizziness, and photosensitivity; serious adverse effects are rare but may involve tendonitis or central nervous system effects. Caution is advised in patients with a history of hypersensitivity to fluoroquinolones, epilepsy, or cardiac arrhythmias. It is contraindicated during pregnancy and lactation unless clearly necessary. Patients should complete the full prescribed course to prevent resistance development. Zanocin 200 should be stored at room temperature, away from moisture and light, and kept out of reach of children.
