Macrolides are a class of antibiotics that are commonly used to treat various bacterial infections. They work by inhibiting bacterial protein synthesis, which prevents the bacteria from growing and multiplying. Macrolides are effective against a range of pathogens, including those that cause respiratory infections, skin infections, and some sexually transmitted diseases. Some well-known examples of macrolides include erythromycin, azithromycin, and clarithromycin. These medications are often preferred for patients who are allergic to penicillin or for those with specific infections where macrolides are particularly effective. While generally safe, they can have side effects and may interact with other medications.
