Meropenem + Sulbactam
Uses of Meropenem + Sulbactam
Meropenem + Sulbactam is a combination antibiotic used in hospital settings to treat severe and life-threatening bacterial infections caused by difficult-to-treat or multi-drug-resistant bacteria. It belongs to the carbapenem and beta-lactamase inhibitor group of medicines.
This combination is commonly used for:
- Hospital-acquired pneumonia and ventilator-associated pneumonia: Treats serious lung infections in hospitalised or ventilated patients caused by resistant bacteria.
- Complicated urinary tract infections: Manages severe kidney and bladder infections that have not responded to other antibiotics.
- Intra-abdominal infections: Treats serious infections inside the abdominal cavity, including peritonitis and complicated appendicitis.
- Septicaemia (bloodstream infection): Used in intensive care settings to treat bacterial infections that have entered the bloodstream.
- Gynaecological infections: Treats severe pelvic infections and postpartum infections caused by susceptible bacteria.
- Meningitis: Used in selected cases of bacterial meningitis when other options are not suitable.
- Skin and soft tissue infections: Treats deep, complicated wound and skin infections caused by multi-drug-resistant organisms.

How Meropenem + Sulbactam works
- Meropenem + Sulbactam works through two complementary antibacterial mechanisms to treat bacterial infections.
- Meropenem is a carbapenem antibiotic. It works by interfering with the synthesis of the bacterial cell wall. Bacteria need a strong cell wall to survive; Meropenem binds to penicillin-binding proteins (PBPs) that are essential for building this wall. Without an intact cell wall, bacteria cannot maintain their structure and die.
- Sulbactam is a beta-lactamase inhibitor. Some bacteria produce enzymes called beta-lactamases that can break down beta-lactam antibiotics, reducing their effectiveness. Sulbactam irreversibly inhibits these enzymes, helping protect Meropenem from degradation and maintaining its antibacterial activity.
- Together, the two components provide broader antibacterial coverage and help overcome certain resistance mechanisms.
