Meropenem Injection (500mg/1g)
Meropenem is a broad-spectrum carbapenem antibiotic used in the management of severe bacterial infections. It works by inhibiting bacterial cell wall synthesis, leading to the destruction of both Gram-positive and Gram-negative bacteria.
Due to its high potency, Meropenem is typically administered via intravenous (IV) infusion in a hospital or clinical setting.
Clinical Uses
Severe Pneumonia: Effective in treating hospital-acquired and community-acquired respiratory infections.
Complicated Urinary Tract Infections (cUTI): Useful against multi-drug-resistant organisms affecting the urinary system.
Intra-abdominal Infections: Treats serious conditions like peritonitis and complications of appendicitis.
Meningitis: Capable of crossing the blood-brain barrier to treat bacterial infections of the brain lining.
Skin and Soft Tissue Infections: Used for deep-seated, chronic, or post-surgical wound infections.
Administration
Route: Given via IV injection or infusion.
Timing: Usually administered every 8 hours, though frequency may vary based on infection severity and kidney function.
Complete the Course: Always finish the full prescribed course. Stopping early can lead to antibiotic resistance (“superbugs”).

Q: Is Meropenem available in capsule form?
A: No. It is available only as an injectable formulation because it is poorly absorbed orally.
Q: How soon does Meropenem start working?
A: Since it is administered directly into the bloodstream, it begins working rapidly. Clinical improvement is usually seen within 48–72 hours.
