M-Cin Tablet contains Moxifloxacin 400 mg, a broad-spectrum fluoroquinolone antibiotic indicated for the treatment of various bacterial infections. Moxifloxacin exerts its bactericidal effect by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination. This action results in the disruption of bacterial DNA processes, leading to cell death. M-Cin is effective against a wide range of Gram-positive and Gram-negative pathogens, including strains resistant to other antibiotics. It is commonly prescribed for respiratory tract infections such as community-acquired pneumonia, acute bacterial sinusitis, and chronic bronchitis exacerbations, as well as skin and soft tissue infections, intra-abdominal infections, and uncomplicated skin infections. The recommended dosage for adults is typically one 400 mg tablet once daily, with or without food, for a duration determined by the severity and type of infection. M-Cin should be used with caution in patients with a history of hypersensitivity to fluoroquinolones, and it is contraindicated in individuals with known tendon disorders related to quinolone use. Adverse effects may include gastrointestinal disturbances, headache, dizziness, and, rarely, tendonitis or QT interval prolongation. It is essential to complete the full prescribed course to prevent resistance development.
