What type of treatment is Raxibacumab used for?

Raxibacumab is a monoclonal antibody specifically designed for the treatment of inhalational anthrax, which is caused by the bacterium Bacillus anthracis. This treatment works by binding to protective antigen component of anthrax toxin, thereby neutralizing the effects of the toxin and helping the body to fight off the infection effectively.

In the context of anthrax exposure, particularly in cases where it may lead to severe respiratory disease, Raxibacumab can be a crucial part of the therapeutic strategy, especially in conjunction with appropriate antibiotic therapy. This makes it the correct choice in the given options, as it directly addresses the specific bacterial infection known as anthrax, rather than other infections or conditions listed.
