Used as a prodrug to improve the lipophilicity and cellular uptake of ceftazidime, enhancing its penetration into bacterial cells. This modification increases the efficacy of the antibiotic against resistant strains, particularly in treating severe Gram-negative infections. Commonly applied in research settings to develop more effective delivery methods for beta-lactam antibiotics. Shows promise in pulmonary delivery systems for treating respiratory infections in cystic fibrosis patients due to improved stability and absorption.
