Recent clinical experience with famciclovir--a "third generation" nucleoside prodrug.
Antiviral chemistry & chemotherapy(2004)
摘要
The herpesviruses continue to produce considerable morbidity in man. Once infected with herpes simplex (HSV), the virus remains dormant within the nervous system and may reactivate if provoked by stress, trauma and/or other factors. To date, there is no cure, but antiviral medication can reduce duration and severity of symptoms and prophylaxis can suppress recurrent episodes of disease. The second-generation guanosine nucleosides, acyclovir and penciclovir, are effective inhibitors with low toxicity; both, however, have relatively low oral bioavailability. Subsequently, the orally bioavailable prodrugs valaciclovir and famciclovir have been introduced. These compounds offer high oral bioavailabilty and deliver acyclovir and penciclovir, respectively, to the target cells by means of more convenient dosing schedules. This short review points to recent experience with famciclovir in the management of HSV and varicella-zoster virus.
