title: Bioavailability of methyl-14C CDP-choline by oral route.
abstract: In this work, the bioavailability of the 14C-methyl-labelled cytidine diphosphate choline (CDP-Choline, citicoline, Somazina), has been studied by oral route, leading to the result that it is slowly and completely absorbed, with a very low urinary and fecal elimination, thus producing maintained blood levels. The bioavailability related to oral route compared with intravenous route is practically the same.
