What two drugs make up the combination known as Unasyn?

• A. Ampicillin and Sulbactam
• B. Piperacillin and Tazobactam
• C. Trimethoprim and Sulfamethoxazole
• D. Ciprofloxacin and Metronidazole

Answer: (A)

Unasyn is a combination antibiotic that specifically includes ampicillin and sulbactam. Ampicillin is a penicillin antibiotic that is effective against a variety of bacterial infections by inhibiting bacterial cell wall synthesis. However, certain bacteria produce enzymes known as beta-lactamases that can deactivate ampicillin. This is where sulbactam comes in; it is a beta-lactamase inhibitor that protects ampicillin from being broken down by these enzymes. Together, they enhance the effectiveness of ampicillin by broadening its spectrum of activity against resistant strains of bacteria. The other options consist of different antibiotic combinations or distinct antibiotics not relevant to Unasyn. Piperacillin and tazobactam, for instance, is another combination but is labeled as Zosyn, while trimethoprim and sulfamethoxazole form a different antibiotic used for other infections. Ciprofloxacin and metronidazole are separate antibiotics that serve different purposes and do not combine to form Unasyn. Thus, the choice that correctly identifies the components of Unasyn is ampicillin and sulbactam.
