Invanz (Ertapenem) is a 1-beta-methyl carbapenem antibiotic that is designed to treat multi drug resistant bacterial infections such as intra-abdominal infections, skin and skin suture infections, community-acquired pneumonia, complicated urinary tract infections including pyelonephritis, acute pelvic infections, and can be used as a prophylactic measure prior to colorectal surgery. Invanz is an injectable antibiotic that can be administered intramuscularly [1][2].
