L-Cin 500 Tablet contains Levofloxacin 500 mg, 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. L-Cin 500 is indicated for the treatment of respiratory tract infections such as community-acquired pneumonia, acute bacterial sinusitis, and chronic bronchitis exacerbations, as well as urinary tract infections including pyelonephritis, skin and soft tissue infections, and prostatitis. The tablet should be administered orally, usually once daily, with or without food, as prescribed by a healthcare professional. Dosage adjustments may be necessary in patients with renal impairment. Common adverse effects include gastrointestinal disturbances, headache, dizziness, and photosensitivity. Serious but rare side effects may involve tendonitis, tendon rupture, peripheral neuropathy, and central nervous system effects. Caution is advised in patients with a history of seizures or QT prolongation. L-Cin 500 should not be used in children, pregnant, or lactating women unless clearly indicated. Proper adherence to prescribed dosage and duration is essential to prevent resistance development.
