Ertapenem sodium is primarily used as an antibiotic to treat a variety of bacterial infections. It is effective against infections caused by both Gram-positive and Gram-negative bacteria, making it a versatile option in clinical settings. Commonly, it is prescribed for complicated intra-abdominal infections, skin and soft tissue infections, community-acquired pneumonia, and urinary tract infections. It is also used in the prevention of surgical site infections following certain procedures. Due to its broad-spectrum activity, it is particularly valuable in cases where the specific causative bacteria are not immediately known. The drug is administered intravenously or intramuscularly, ensuring rapid and effective delivery to the site of infection. Its use is often reserved for more severe infections or when other antibiotics have proven ineffective, helping to reduce the risk of antibiotic resistance.
