Narrow-spectrum antibiotics are medications designed to target specific types of bacteria. Unlike broad-spectrum antibiotics, which affect a wide range of bacteria, narrow-spectrum antibiotics are more selective, making them effective against particular strains. This targeted approach helps minimize the impact on beneficial bacteria in the body. Using narrow-spectrum antibiotics can reduce the risk of developing antibiotic resistance, a growing concern in medicine. By focusing on specific bacteria, these antibiotics can effectively treat infections while preserving the body's natural microbiome. Examples of narrow-spectrum antibiotics include penicillin and vancomycin, which are used to treat specific bacterial infections.
