Kiocef-O Tablet is a combination antibiotic formulation containing Cefixime 200 mg and Ofloxacin 200 mg, indicated for the treatment of a wide range of bacterial infections. Cefixime, a third-generation cephalosporin, exerts its bactericidal action by inhibiting bacterial cell wall synthesis, thereby effectively targeting susceptible Gram-positive and Gram-negative organisms. Ofloxacin, a fluoroquinolone antibiotic, inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication and transcription, providing broad-spectrum activity against various aerobic Gram-negative and Gram-positive pathogens. The synergistic effect of these two agents enhances the antimicrobial spectrum and reduces the likelihood of resistance development. Kiocef-O is commonly prescribed for infections such as urinary tract infections, respiratory tract infections, otitis media, gonorrhea, and skin and soft tissue infections caused by susceptible bacteria. It is essential to complete the full prescribed course to prevent the emergence of resistant strains. Caution is advised in patients with hypersensitivity to cephalosporins or fluoroquinolones, and use during pregnancy and lactation should be under medical supervision. Adverse effects may include gastrointestinal disturbances, headache, dizziness, and hypersensitivity reactions. Kiocef-O Tablet should be used strictly as directed by a healthcare professional to ensure optimal therapeutic outcomes.
