Steady state pharmacokinetics of oral treatment with 13-cis-retinoic acid or all-trans-retinoic acid in male and female adult rats.

Male and female Sprague-Dawley rats were orally gavaged with 13-cis-retinoic acid (7.5 or 15 mg/kg) or all-trans-retinoic acid (10 or 15 mg/kg) for 7 consecutive days. Blood was collected out to 8 hr after the last gavage on day 7. HPLC serum concentrations of 13-cis-retinoic acid, all-trans-retinoic acid, and 13-cis-4-oxo-retinoic acid were subjected to model independent pharmacokinetic analyses. Peak serum levels of 563 to 1640 ng/ml were observed for rats treated with 13-cis-retinoic acid at 1.5-2 hr after gavage. Peak serum levels of 183 to 267 ng/ml at 1.5 hr after gavage were observed for all-trans-retinoic acids. The elimination half-life of 13-cis-retinoic acid was about 1.5 hr while the elimination half-life of all-trans-retinoic acid was slightly longer. There were no sex differences for any parameter. Serum levels resulting from the 7.5 mg/kg 13-cis-retinoic acid were similar to those of human Accutane users.[1]
