Pharmacokinetics
With intravaginal use, systemic absorption of metronidazole is minimal. The half-life of metronidazole that has entered the systemic circulation is 8-10 hours. Less than 20% of metronidazole binds to blood proteins. There is a rapid and pronounced diffusion into the lungs, kidneys, liver, bile, cerebrospinal fluid, skin, saliva and vaginal secretions. It crosses the placenta and is excreted in breast milk. It is metabolized in the liver to form two unconjugated oxidized active metabolites (5-30% activity). Excretion of the drug occurs mainly by the kidneys: 35-65% is excreted in the urine unchanged and in the form of metabolites.
