This anhydrous form of imipenem is the active component used in combination antibiotic preparations (typically with cilastatin) to treat severe gram-negative and gram-positive bacterial infections. It works by binding to penicillin-binding proteins to inhibit bacterial cell wall construction. The anhydrous form refers to the compound without bound water molecules used in formulation.
