[Pharmaokinetics of beta-escin after administration of various Aesculus extract containing formulations].

Abstract

With a specific radioimmunoassay the pharmacokinetics and relative bioavailability of escin was measured after administration of different formulations containing Aesculus-extract. Of special interest was the relative bioavailability of escin after administration of a newly developed film-coated tablet with sustained release in comparison to a reference formulation. In a cross-over steady-state study in 24 volunteers bioequivalence of test and reference preparation could be demonstrated. The 90% confidence interval of the AUC (O-tau) was 98.3 to 120.9%.
