Faropenem sodium is primarily used as an antibiotic to treat various bacterial infections. It is effective against a wide range of gram-positive and gram-negative bacteria, making it useful in treating respiratory tract infections, such as bronchitis and pneumonia, as well as urinary tract infections, skin and soft tissue infections, and ear infections. Its broad-spectrum activity allows it to target bacteria that may be resistant to other antibiotics. Additionally, it is often prescribed for community-acquired infections due to its efficacy and relatively low risk of side effects. The drug is typically administered orally, making it convenient for outpatient treatment.
