Spectrum of bacterial coverage:


Piperacillin has an antimicrobial activity against a wide range of gm-ve organisms including K. pneumoniae, P. aeruginosa, Enterobacteriaceae and against gm+ve organisms eg E. faecalis and B. fragilis. Tazobactam is a penicillanic acid sulfone derivative with beta-lactamase inhibitory properties. In combination, tazobactam enhances the activity of piperacillin against beta-lactamase-producing bacteria.

This antibiotic is used for a variety of severe bacterial infections. Some of them are explained below-




Pnemonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing


Hospital-acquired pneumonia


Some people catch pneumonia during a hospital stay for another illness. Hospital-acquired pneumonia can be serious because the bacteria causing it may be more resistant to antibiotics and because the people who get it are already sick. People who are on breathing machines (ventilators), often used in intensive care units, are at higher risk of this type of pneumonia.




Septicemia is a life-threatening complication of an infection. Sepsis occurs when chemicals released in the bloodstream to fight an infection trigger inflammation throughout the body. This can cause a cascade of changes that damage multiple organ systems, leading them to fail, sometimes even resulting in death.
