Piperacillin is a type of antibiotic that belongs to the penicillin group. It is primarily used to treat various bacterial infections, including those affecting the lungs, skin, and urinary tract. Piperacillin works by interfering with the bacteria's ability to form cell walls, ultimately leading to their destruction. This medication is often combined with tazobactam, a beta-lactamase inhibitor, to enhance its effectiveness against resistant bacteria. Piperacillin/tazobactam is commonly administered in hospitals, especially for serious infections. It is important to use this antibiotic only under medical supervision to prevent antibiotic resistance.
