What is the main function of antibiotics?

Antibiotics serve the primary purpose of preventing or treating infections caused by bacteria. They work by either killing bacteria or inhibiting their growth, which helps the body's immune system to manage and eliminate the infection effectively. This function is crucial in healthcare, as bacterial infections can lead to severe complications if not treated appropriately.

While other medications may address different health concerns—such as lowering blood pressure or acting as muscle relaxants—these functions do not relate to the role of antibiotics. Similarly, treating depression falls under the purview of psychiatric medications, not antibiotics. Understanding the specific role of antibiotics is essential for anyone in the medical field, particularly medication aides, as it involves administering medications that can significantly impact patient care and recovery.
