Ertapenem is a type of antibiotic belonging to the carbapenem class, which is used to treat a variety of bacterial infections. It works by inhibiting the growth of bacteria, making it effective against many strains that are resistant to other antibiotics. Ertapenem is typically administered through an injection and is often used in hospital settings. This medication is particularly useful for treating infections in the abdomen, skin, and respiratory tract. It is important to use ertapenem only under the guidance of a healthcare professional to ensure its effectiveness and to minimize the risk of developing antibiotic resistance.
