DNA single strand-breaks were examined in lymphocytes of patients treated with metronidazole (CAS 443-48-1) for trichomonas vaginalis infection before, on day one, and day seven of treatment. Recommended dosage of metronidazole induces DNA single strand-breaks. Single strand-breaks were repaired after therapy. No irreversible DNA damage remains. The DNA repair mechanisms are genetically determined. Therefore a mutagenic effect of metronidazole must be discussed in patients with DNA repair defects.
