Carbapenems are a class of antibiotics that are effective against a wide range of bacteria, including many that are resistant to other antibiotics. They work by inhibiting bacterial cell wall synthesis, which ultimately leads to the death of the bacteria. Commonly used carbapenems include meropenem and imipenem. These antibiotics are often reserved for severe infections caused by multidrug-resistant organisms. Due to their broad-spectrum activity, carbapenems are crucial in treating infections in hospitalized patients, especially those with weakened immune systems. However, their use is carefully monitored to prevent the development of further antibiotic resistance.
