Durlobactam Injection and Sulbactam Injection

The combination of durlobactam injection and sulbactam injection is used to treat certain types of pneumonia that developed in adults who are on ventilators or who were already in a hospital. Sulbactam is in a class of medications called penicillin-like antibiotics. It works by stopping the growth of certain bacteria. Durlobactam is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying sulbactam.

Antibiotics such as durlobactam and sulbactam injection will not work for colds, flu, or other viral infections. It works by stopping the growth of bacteria. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

The combination of durlobactam and sulbactam injection comes as a powder to be mixed with liquid and injected intravenously (into a vein). It is usually infused (injected slowly) intravenously over a period of 3 hours every 6 hours for 7 to 14 days. The length of treatment depends on your general health and how well you respond to the medication.
