Herpes Zoster research study

What is the primary objective of this study?

Herpes Zoster is an infection that affects part of the nervous system caused by Varicella Zoster Virus. Herpes Zoster manifests as vesicular eruption in the dermatome, often associated with significant pain. There are effective oral prescription antiviral medicines available to reduce the discomfort of symptoms as famciclovir and aciclovir. This is a phase III, multicenter, randomized, parallel-group study to compare the efficacy and safety of treatment with Famciclovir (500 mg) comparing to Aciclovir (400 mg) in patients with Herpes Zoster.
