Which infection is Teflaro (ceftaroline) primarily used to treat?

Teflaro (ceftaroline) is primarily used to treat MRSA skin infections due to its unique pharmacological profile. Ceftaroline is a cephalosporin antibiotic that has a broad spectrum of activity, particularly effective against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). This characteristic makes it a valuable option in the treatment of complicated skin and skin structure infections caused by this pathogen.

While Teflaro does have some efficacy against certain Gram-negative bacteria, it is specifically designated as a treatment for MRSA, distinguishing it from other antibiotics that might target a wider array of Gram-negative infections. Furthermore, its use for bone infections is not its primary indication, and it is not recommended for pneumonia caused by Pseudomonas, where alternative antibiotics would typically be preferred due to their greater effectiveness against this organism. Therefore, its primary use cases revolve around combating MRSA, making option B the correct choice.
