Step-by-step explanation:
Broad spectrum antipseudomonal penicillin are a group of antibiotics that have a wide range of activity against both gram-positive and gram-negative bacteria, including many strains that produce β-lactamase, an enzyme that can render some antibiotics ineffective.
Examples of broad spectrum antipseudomonal penicillin include piperacillin and tazobactam, which possess strong activity against Pseudomonas aeruginosa and other multidrug-resistant bacteria.
These antibiotics are often used in the treatment of severe infections, such as pneumonia, urinary tract infections, and intra-abdominal infections.
