Answer

Answer

The bioavailability of acyclovir is approximately 8%. The bioavailability of famciclovir and valacyclovir is approximately 50%. Now that famciclovir and valacyclovir have been approved, choosing either agent seems advisable when switching from intravenous acyclovir to an oral agent.
