Mode of Action
Metronidazole 400mg UK works by disrupting the DNA of susceptible microorganisms. After entering the microbial cell, the drug is reduced by intracellular transport proteins found in anaerobic bacteria and protozoa. This reduction process creates reactive nitro radicals, which bind to DNA and cause strand breaks. The damaged DNA cannot be replicated or repaired, leading to cell death.
