In terms of pharmacological intervention, what medication is commonly used to treat anthrax exposure?

• A. Amoxicillin or azithromycin
• B. Ciprofloxacin or doxycycline
• C. Vancomycin or penicillin
• D. Rifampicin or cephalexin

Answer: (B)

The commonly used medications to treat anthrax exposure are ciprofloxacin and doxycycline. These antibiotics are effective against Bacillus anthracis, the bacterium that causes anthrax, as they are part of the recommended post-exposure prophylaxis guidelines. Ciprofloxacin is a fluoroquinolone antibiotic that works by inhibiting bacterial DNA gyrase, thus preventing bacterial replication. Doxycycline is a tetracycline antibiotic that inhibits protein synthesis in bacteria, rendering them unable to grow and reproduce. Both of these antibiotics are preferred due to their ability to penetrate various tissues and their good oral bioavailability, making them effective in both prevention and treatment of anthrax, particularly when administered promptly after exposure. In the case of inhalational anthrax or other serious forms of the infection, these medications can be combined with additional treatments to ensure a comprehensive therapeutic approach. Other medications mentioned, such as amoxicillin or azithromycin, have lesser roles in anthrax treatment protocols due to resistance concerns or are not the first choices in such scenarios. Vancomycin usually targets Gram-positive bacteria, and cephalexin may not provide adequate coverage for anthrax. Rifampicin is typically used for specific bacterial infections and is not first-line for anthrax exposure.
