What is narrow range spectrum antibiotics?

Narrow-spectrum antibiotics are medications that specifically target a limited range of bacteria, usually either Gram-positive or Gram-negative organisms, rather than a broad array of bacterial species. This targeted approach helps minimize the impact on the body's normal flora and reduces the risk of developing antibiotic resistance. They are often used when the specific type of infection-causing bacteria is known, allowing for precise treatment. Examples include penicillin, which primarily affects Gram-positive bacteria.
