    Cefpodoxime, sold under the brand name Vantin among others, is an antibiotic used to treat middle ear infections, strep throat, sinusitis, urinary tract infections, and gonorrhea.[2] It is taken by mouth.[2]

    Common side effects include diarrhea, nausea, vaginal yeast infections, abdominal pain, and headache.[3] Other side effects may include allergic reactions and Clostridioides difficile infection.[2] While there is no evidence of harm with use in pregnancy, such use has not been well studied.[4] It is a third-generation cephalosporin and works by interfering with the bacterial cell wall.[1]

    Cefpodoxime was patented in 1980 and approved for medical use in 1989.[5] It is available as a generic medication.[2] In the United States 20 tablets of 200 mg costs about 36 USD as of 2021.[6]

    Medical uses

    Spectrum of activity

    Cefpodoxime has been used to fight pathogenic bacteria responsible for causing gonorrhoea, tonsillitis, pneumonia, and bronchitis. Representative pathogenic genera include Streptococcus, Haemophilus, and Neisseria. The following represents MIC susceptibility data for a few medically significant microorganisms.[7]

    • Haemophilus influenzae: ≤0.03 - 1 μg/ml
    • Neisseria gonorrhoeae: 0.004 - 0.06 μg/ml
    • Streptococcus pyogenes: ≤0.004 - 2 μg/ml

    Dosage

    It is used at a dose of 200 to 800 mg per day.[3] This may be take as a single dose or divided into two doses.[3] Treatment may vary from 5 to 14 days.[3]

    Mechanism of action

    Cefpodoxime inhibits cell wall synthesis by inhibiting the final transpeptidation step of peptidoglycan synthesis in cell walls. It has well established pharmacokinetic profile with absorption of 50%.
