Pefloxacin Action Pathway

Haemophilus influenzae

Drug Action Pathway

Pefloxacin is an antibiotic used to treat a variety of bacterial infections. Pefloxacin inhibits DNA gyrase (topoisomerase II) and topoisomerase IV. These proteins prevent supercoiling in bacterial DNA. The inhibition of DNA gyrase (topoisomerase II) and topoisomerase IV causes supercoiling of the bacterial DNA. This prevents DNA replication.
