What type of infections is Baxdela (Delafloxacin) primarily used to treat?

Baxdela (Delafloxacin) is primarily utilized for the treatment of acute bacterial skin infections. This medication belongs to the fluoroquinolone class of antibiotics and is specifically indicated to combat skin and soft tissue infections caused by susceptible bacteria. Its effective mechanism targets bacterial DNA synthesis, making it particularly useful in cases where other antibiotics might not be as effective due to resistance.

In the context of the other options, while upper respiratory infections, urinary tract infections, and gastrointestinal infections can also be caused by bacteria, they are not the primary focus for the use of Baxdela. This antibiotic is not specifically indicated for those types of infections, although it may have some activity against certain pathogens involved in them. However, its clinical utility is firmly established in treating acute bacterial skin and skin structure infections, which is why it is the correct response in this instance.
