Sulbactam/durlobactam, sold under the brand name Xacduro, is a co-packaged medication used to treat bacterial pneumonia caused by Acinetobacter baumannii-calcoaceticus complex.[1] It is given by injection into a vein over 3 hours.[1] The other primary treatment for this condition is colistin.[2]
Common side effects include liver problems, low red blood cells, diarrhea, and low potassium.[1] Other side effects may include allergic reactions and Clostridioides difficile-associated diarrhea.[1] It contains sulbactam, a beta-lactam antibacterial and beta-lactamase inhibitor; and durlobactam, a beta-lactamase inhibitor.[1]
Sulbactam/durlobactam was approved for medical use in the United States in 2023.[1] It was not currently available commercially as of August 2023, but was expected to become available in later 2023 in the United States.[3]
Medical uses
Sulbactam/durlobactam is indicated for the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia, caused by susceptible isolates of Acinetobacter baumannii-calcoaceticus complex.[1][4]
Dosage
The typical dose is 1 gram sulbactam and 1 gram durlobactam four times per day.[1]
History
The efficacy of sulbactam/durlobactam was established in a multicenter, active-controlled, open-label (investigator-unblinded, assessor-blinded), non-inferiority clinical trial in 177 hospitalized adults with pneumonia caused by carbapenem-resistant A. baumannii.[4] Participants received either sulbactam/durlobactam or colistin (a comparator antibiotic) for up to 14 days.[4] Both treatment arms also received an additional antibiotic, imipenem/cilastatin, as background therapy for potential hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia pathogens other than Acinetobacter baumannii-calcoaceticus complex.[4] The primary measure of efficacy was mortality from all causes within 28 days of treatment in participants with a confirmed infection with carbapenem-resistant A. baumannii.[4] Of those who received sulbactam/durlobactam, 19% (12 of 63 participants) died, compared to 32% (20 of 62 participants) who received colistin; this demonstrated that sulbactam/durlobactam was noninferior to colistin.[4]
