Beta-lactam antibiotics are a class of medications used to treat bacterial infections. They work by inhibiting the synthesis of bacterial cell walls, which ultimately leads to the death of the bacteria. Common examples include penicillin, amoxicillin, and cephalosporins. These antibiotics are effective against a wide range of bacteria, making them a popular choice in medical treatments. Despite their effectiveness, some bacteria have developed resistance to beta-lactam antibiotics, making it crucial to use them appropriately. This resistance can occur through various mechanisms, such as producing enzymes that break down the antibiotic. Ongoing research aims to combat this resistance and improve treatment options for bacterial infections.
