title: A pilot study of BW A515U (6-deoxyacyclovir) in chronic hepatitis B virus infection.
abstract: BW A515U (6-Deoxyacyclovir) is a pro-drug of acyclovir and almost 100% is absorbed orally. 250 mg orally 6-hourly for 10 days was given to 4 hepatitis B surface antigen/e antigen-positive carriers. No consistent effect on productive viral replication, as determined by serum DNA polymerase and DNA levels was observed. The changes that occurred in these markers and transaminases in 1 patient were attributed to a spontaneous depression of productive viral replication.
