A carbapenem derivative antibacterial agent that is more stable to renal dehydropeptidase I than IMIPENEM, but does not need to be given with an enzyme inhibitor such as CILASTATIN. It is used in the treatment of Gram-positive and Gram-negative bacterial infections including intra-abdominal infections, acute gynecological infections, complicated urinary tract infections, skin infections, and respiratory tract infections. It is also used to prevent infection in colorectal surgery.

4 Drug and Medication Information
4.1 Drug Indication

* Treatment:

Treatment of the following infections when caused by bacteria known or very likely to be susceptible to ertapenem and when parenteral therapy is required:

- intra-abdominal infections;

- community-acquired pneumonia;

- acute gynaecological infections;

- diabetic foot infections of the skin and soft tissue.

* Prevention:

Invanz is indicated in adults for the prophylaxis of surgical site infection following elective colorectal surgery.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.
