Tazobactam is a beta-lactamase inhibitor that is often used in combination with certain antibiotics to enhance their effectiveness against resistant bacteria. It works by blocking the enzymes produced by some bacteria that can break down antibiotics, allowing the drugs to work more effectively. Typically, tazobactam is combined with piperacillin, a penicillin-type antibiotic, to treat various infections, including those in the respiratory tract, skin, and urinary system. This combination helps to broaden the spectrum of activity against a range of bacteria, making it a valuable option in clinical settings.
