Meromer SB 1.5gm Injection is an antibiotic medication that contains two active ingredients called Meropenem and Sulbactam. It belongs to the medication class known as carbapenem antibiotics. It is used to treat various bacterial infections caused by susceptible organisms. Also, it is used to treat pneumonia, urinary tract infections, intra-abdominal infections, gynaecological infections, skin infections, meningitis, and sepsis. Harmful bacteria release toxins that harm tissues and cause illness. This medicine works by preventing bacteria from forming their protective cover, which is crucial for their survival. Sulbactam inhibits bacterial enzymes that can deactivate Meropenem. Meropenem may be used to manage neutropenic patients with fever suspected to be due to a bacterial infection.
