Mero-O 200 Tablet contains Faropenem 200 mg, a broad-spectrum oral carbapenem antibiotic effective against a wide range of Gram-positive and Gram-negative bacterial infections. Faropenem exerts its bactericidal action by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins, leading to cell lysis and death. Mero-O 200 is indicated for the treatment of respiratory tract infections, urinary tract infections, skin and soft tissue infections, and other bacterial infections caused by susceptible organisms. It is particularly useful in cases where resistance to other beta-lactam antibiotics is a concern. The tablet is typically administered orally, with dosage and duration tailored according to the severity and type of infection, as well as patient-specific factors such as renal function. Mero-O 200 is generally well tolerated; however, potential side effects may include gastrointestinal disturbances such as nausea, diarrhea, and abdominal discomfort. Hypersensitivity reactions, although rare, may occur in patients with a history of beta-lactam allergy. Caution is advised in patients with renal impairment, and dosage adjustments may be necessary. As with all antibiotics, it is essential to complete the prescribed course to prevent the development of resistance. Mero-O 200 should be used under medical supervision following susceptibility testing where possible.
