It has a slow onset time which lasts about 6 ~ 7min and the duration time of about 1.5 ~ 2h. It has a strong penetration capability through mucous membranes. Adrenaline has a slightly prolonged duration of action. PPB is 55% and T1/2 of about 1.5h. It is subject to liver metabolism with its metabolites nitroso toluidine being able to oxidize hemoglobin to form methemoglobin. It can be transported to the fetus through the placenta.
