Which antibiotic is preferred in the management of tetanus?

• A. Ciprofloxacin
• B. Vancomycin
• C. Metronidazole
• D. Amoxicillin

Answer: (C)

Metronidazole is the preferred antibiotic in the management of tetanus due to its efficacy against Clostridium tetani, the bacterium responsible for the disease. This antibiotic works by disrupting the DNA synthesis of anaerobic bacteria, which includes the tetanus pathogen. Given that metronidazole is effective at lower doses and penetrates well into tissues, it is particularly well-suited for treating infections that require anaerobic coverage, such as tetanus. While other antibiotics listed have their uses in different contexts, they do not target Clostridium tetani effectively. Ciprofloxacin is primarily effective against aerobic Gram-negative bacteria and does not have significant activity against anaerobes. Vancomycin is important for treating infections caused by certain Gram-positive bacteria, especially methicillin-resistant Staphylococcus aureus, but it is not indicated for tetanus. Amoxicillin is a broad-spectrum penicillin, which may have some anaerobic coverage but is not the first choice for tetanus management. Thus, metronidazole stands out as the most appropriate option for treating tetanus, given its specific action against the causative organism.
