Ceftibuten is primarily used as an antibiotic to treat various bacterial infections. It is effective against respiratory tract infections such as bronchitis and pneumonia, as well as ear infections like otitis media. Additionally, it is prescribed for urinary tract infections caused by susceptible bacteria. The drug works by inhibiting bacterial cell wall synthesis, making it a valuable option for patients who require oral antibiotic therapy. Its broad-spectrum activity and convenient dosing regimen make it suitable for both adults and children in managing mild to moderate infections.
