Zoxan OZ Tablet is a combination antibiotic formulation containing Ciprofloxacin 500 mg and Ornidazole 500 mg, indicated for the treatment of mixed bacterial and protozoal infections. Ciprofloxacin, a fluoroquinolone antibiotic, exhibits broad-spectrum activity against Gram-negative and some Gram-positive bacteria by inhibiting bacterial DNA gyrase and topoisomerase IV, thereby preventing DNA replication and transcription. Ornidazole, a nitroimidazole derivative, is effective against anaerobic bacteria and protozoa by causing DNA strand breakage and inhibiting nucleic acid synthesis. This synergistic combination is particularly useful in managing infections such as gastrointestinal infections, intra-abdominal infections, pelvic inflammatory disease, and certain dental infections where both aerobic and anaerobic pathogens are implicated. Zoxan OZ Tablet should be administered as prescribed by a healthcare professional, typically twice daily, with the duration depending on the severity and type of infection. Caution is advised in patients with a history of hypersensitivity to fluoroquinolones or nitroimidazoles, and it is contraindicated in pregnancy and lactation unless clearly necessary. Common adverse effects may include gastrointestinal disturbances, dizziness, and headache. Proper adherence to the prescribed regimen is essential to prevent resistance development and ensure therapeutic efficacy.
