Worldwide, antibiotic resistance is a major contemporary public health threat due to rapid emergence of resistant bacteria and endangering the eicacy of antibiotics. There are signiicant number of reports on clinical failure of β-lactam and β-lactamase inhibitor combination and even carbapenems due to various carbapenem resistance mechanisms. The increasing rate of the antibiotic resistance and its impact on treatment failure encouraged us to study newly reported concept of antibiotic adjuvant entities (AAEs) by which the increasing failure rate of antibiotics can be controlled. These AAEs have been developed for both Gram-positive and Gram-negative multidrug-resistant (MDR) infections. Elores (ceftriaxone + sulbactam with adjuvant ethylenediaminetetraacetic acid (EDTA)) and Potentox (cefepime + amikacin with adjuvant potassium chloride) are the AAEs for Gram-negative MDR pathogens each catering to a diferent type of resistance and Vancoplus (ceftriaxone + vancomycin with adjuvant L-arginine), another AAE, can help us to last longer in the war against antibiotic-resistant Gram-positive bugs particularly which cause complicated lower respiratory tract infection (LRTI) leading to pneumonia. These new antibiotic additions (Elores, Potentox, and Vancoplus) to the current armamentarium to treat MDR infections, including pneumonia, can help us combat against antimicrobial resistance more eiciently.
