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 for healthcare providers to choose the right antibiotic based on the specific infection. Proper use and adherence to prescribed treatments can help reduce the risk of antibiotic resistance.
