title: [Stability of antilipidemic etofibrate and its metabolites towards gastrointestinal and blood hydrolases (author's transl)].
abstract: Etofibrate is preferentially cleaved in its clofibrinic acid ester group by the hydrolases of the blood. The formed nicotinic acid 2-hydroxyethyl ester is considerably more stable than the 2-(4-chlorophenoxy)-2-methylpropionic acid (2-hydroxyethyl)-ester. Against artificial gastric and intestinal juice (USP XIX), the nicotinic acid 2-hydroxyethyl ester is almost completely stable. Etofibrate is bound to plasma albumin substantially more tightly than is clofibrate.
