What does Azithromycin do in the treatment of CF?

  1. Improves kidney function

  2. Disrupts biofilm production

  3. Increases heart rate

  4. Enhances carbohydrate breakdown

The correct answer is: Disrupts biofilm production

Azithromycin is commonly used as an antibiotic to treat various bacterial infections, including respiratory tract infections seen in patients with cystic fibrosis (CF). It works by inhibiting the production of certain proteins that are necessary for bacteria to grow and multiply. This disruption of biofilm production makes it easier for the body's immune system to fight off the infection. Option A, improving kidney function, is incorrect because Azithromycin does not have any direct effect on the kidneys. Option C, increasing heart rate, is incorrect because Azithromycin does not have any direct effect on the heart. Option D, enhancing carbohydrate breakdown, is incorrect because Azithromycin does not have any direct effect on metabolism or digestion.
