Zefu 500 Tablet contains Cefuroxime 500mg, a second-generation cephalosporin antibiotic effective against a broad spectrum of bacterial infections. Cefuroxime exerts its bactericidal action by inhibiting bacterial cell wall synthesis, leading to cell lysis and death. This medication is indicated for the treatment of respiratory tract infections such as bronchitis and pneumonia, urinary tract infections, skin and soft tissue infections, otitis media, and Lyme disease. Zefu 500 is particularly useful in infections caused by susceptible strains of Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, and Staphylococcus aureus. The tablet formulation allows for convenient oral administration with good bioavailability. Dosage and duration of therapy should be determined based on the severity and type of infection, as well as patient-specific factors including renal function. Common adverse effects may include gastrointestinal disturbances such as diarrhea, nausea, and abdominal discomfort, while hypersensitivity reactions, though less frequent, can occur in patients with a history of beta-lactam allergy. Caution is advised in patients with renal impairment, and concurrent use with other nephrotoxic drugs should be monitored. Zefu 500 Tablet should be used under medical supervision to ensure appropriate use and to minimize the development of antibiotic resistance.
