🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by entering susceptible microorganisms and undergoing reduction of its nitro group, which creates reactive intermediates that damage microbial DNA. This damage breaks the DNA strands and inhibits nucleic acid synthesis, leading to rapid cell death of anaerobic bacteria and protozoa. Because the activation occurs only in low-oxygen environments, the medicine is selective for anaerobic organisms and has little effect on normal human cells.
