    Product Description

    Ertapenem is a long-acting, broad-spectrum antibiotic that is in the β-lactam subclass known as carbapenems.1,2,3 It inhibits the synthesis of bacterial cell walls by attaching to penicillin-binding proteins. Ertapenem is effective against Gram-positive and Gram-negative bacteria.4,5 Resistance to ertapenem results from the expression of certain β-lactamases and carbapenemases.6

    WARNING This product is not for human or veterinary use.
