Penicillins

Penicillins are a group of antibiotics that help fight bacterial infections by preventing bacteria from building their cell walls, which are essential for their survival. This action kills or halts the growth of bacteria, allowing the immune system to eliminate the infection. Penicillins are effective against a variety of bacterial diseases, including sore throats, skin infections, and pneumonia. They were among the first antibiotics discovered and have saved countless lives. However, some bacteria have developed resistance, making it important to use them appropriately under medical supervision.
