The effect of divalproex sodium on HIV replication in vivo.

In vitro data suggest valproate activates HIV replication. This study prospectively assesses whether divalproex sodium causes an increase in HIV replication in patients. Eight participants had their HIV viral load measured over approximately 1 month. The largest increases in viral load occurred in patients without antiretroviral medication. No patients had an increase in Log10 HIV viral load > or = 0.5. Further study is needed to understand implications.
