How Flagyl Works?

Flagyl belongs to the nitroimidazole class of antibiotics, it can interact with the DNA of the microorganism. Binding to DNA causes strand breaks and cross-linking of DNA molecules. This disrupts the normal structure and function of DNA, ultimately inhibiting the replication and transcription processes necessary for the survival and growth of the microorganism.
