Absorption: Rapidly absorbed after oral administration with an oral bioavailability of about 80%.
  • Distribution: 50% bound to plasma proteins. Crosses the blood brain barrier.
  • Metabolism: Undergoes intracellular metabolism to carbovir triphosphate which is the active metabolite.
  • Excretion: Elimination half-life: About 1.5 hr after a single oral dose. Elimination by hepatic metabolism mainly by alcohol dehydrogenase and glucuronidation. The metabolites are excreted mainly in the urine.
