Merrobe 0.5g Injection Merrobe 0.5g contains Meropenem, an ultra-broad-spectrum beta-lactam antibiotic belonging to the carbapenem subgroup. It functions by readily penetrating bacterial cell walls and binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan synthesis and causing bacterial cell wall breakdown and cell death. It is resistant to degradation by most bacterial beta-lactamases, including penicillinases and cephalosporinases. It is indicated for the treatment of severe or complicated bacterial infections in adults and pediatric patients, including intra-abdominal infections, severe community-acquired and hospital-acquired pneumonia, complicated skin and skin structure infections, complicated urinary tract infections, bacterial meningitis, and septicemia.
