Antibiotics: Explanation and Study Guide

Explanation

Antibiotics are medicines used to treat bacterial infections. They work by targeting and killing the bacteria that are causing the infection. It's important to note that antibiotics are not effective against viral infections such as the common cold or flu.

There are different classes of antibiotics, each with its own mechanism of action and spectrum of activity. Some common classes of antibiotics include penicillins, cephalosporins, tetracyclines, macrolides, and fluoroquinolones.

When taking antibiotics, it's crucial to follow the prescribed dosage and complete the full course of treatment, even if you start feeling better before the medication is finished. This helps to prevent the development of antibiotic resistance.
