Piperacillin is a semisynthetic penicillin with wide spectrum of antimicrobial activity, particularly pseudomonas strains. Piperacillin is a broad-spectrum antibiotic belonging to the penicillin class. It works by inhibiting bacterial cell wall synthesis, leading to the elimination of various bacterial infections. Often combined with tazobactam, it provides an extended spectrum of activity against both Gram-positive and Gram-negative bacteria.
