Abstract:Bioavailability of acetylated derivatives of digoxin tablets have been studied in healthy subjects after a single oral and intravenous dose as well as during maintenance therapy. alpha-acetyldigoxin shows a lower bioavailability than beta-acetyldigoxin even if the alpha-acetylated derivative is incorporated in a matrix of aerosil (SiO2). Moreover, beta-acetyldigoxin can be transferred to alpha-acetyldigoxin in alkaline solutions. This isomerisation leads to a decrease of the bioavailability of such fixed prepa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
