Abstract:Ribavirin (RBV), a guanosine analog for treatment of hepatitis C, is a substrate of a nucleoside transporter, solute carrier family 29 member 1 (SLC29A1). To clarify the impact of SLC29A1 on the pharmacokinetics of RBV, an open-label, crossover study of single-dose RBV (200 mg, p.o.) with and without coadministration of dipyridamole (DP), an inhibitor of SLC29A1, was performed. Plasma and erythrocyte concentrations of RBV in the control phase and DP phase (25 mg, 3 times daily for 4 days) were compared in 10 h… 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.
