Ceftazidime is a third-generation cephalosporin antibiotic used to treat a wide range of bacterial infections, including serious infections such as pneumonia, urinary tract infections, and sepsis. It is particularly effective against Gram-negative bacteria and is commonly used in hospital settings. Ceftazidime is approved and widely used today.
Pharmacokinetics
