Popis: The pharmacokinetics of folic acid, and resultant metabolites thereof, have been determined after administration orally and intravenously at 25 mg/m2 and 125 mg/m2. Saturation behavior was observed for uptake of folic acid into plasma and with regard to metabolism to methylenetetrahydrofolate and tetrahydrofolate as well as methyltetrahydrofolate. Repetitive oral administration every 6 hours resulted in consistently elevated levels of each metabolite pool with the same general saturation behavior as observed with single dose administration. This repetitive oral administration is concluded to be a suitable means to provide uniform elevation of metabolites that could offer protection from undesirable toxic effects of drugs such as MTA.
