Pharmacokinetics of dexamethasone and its phosphate ester. 1987

P Rohdewald, and H Möllmann, and J Barth, and J Rehder, and H Derendorf

Dexamethasone in form of its phosphate was given intravenously in two different doses (1.5 mg kg-1 and 15 mg). Plasma levels of the ester and dexamethasone were measured and pharmacokinetic parameters were calculated. The results indicate no dose-dependency of the pharmacokinetic parameters in the investigated range for dexamethasone. Conversion from the prodrug to the active form was rapid; maximum dexamethasone plasma concentrations were reached after 10 min. The results were verified by dexamethasone level monitoring in patients after chronic dosing. Predicted and achieved steady state levels agreed well.
