NCIt definition : A synthetic thymidine analogue with potent antiviral activity against herpes simplex
and varicella zoster viruses. Sorivudine is phosphorylated into triphosphate form
within the cells; this metabolite interferes with viral DNA replication by inhibiting
DNA polymerase activity without been incorporated into elongating viral DNA. Due to
the dangerous effects of drug-drug interactions via its metabolite, sorivudine has
been removed from the market.;
