What is the primary use of cefoperazone?

Cefoperazone is primarily utilized in the treatment of infections caused by Pseudomonas aeruginosa, a common pathogen known for its resistance to many antibiotics. This cephalosporin antibiotic is particularly effective against Gram-negative bacteria, making it suited for severe infections where Pseudomonas is involved. It is often chosen in clinical settings for patients with conditions like pneumonia or other infections in which this organism is suspected or confirmed.

The other options, while they may be relevant for other antibiotics, do not represent the primary focus of cefoperazone's prescribing practices. For instance, cefoperazone is not typically the first-line treatment for respiratory, skin, or genital infections, as other antibiotics are more commonly utilized for those types of infections. Thus, its specific activity against Pseudomonas makes it a key drug in combating these challenging infections.
