Yes. Many of the "post-acute withdrawal" symptoms - anxiety, sleeplessness, craving for alcohol, may be reduced by acamprosate, which reduces the level of a chemical in the brain (glutamate) which appears to be responsible for many of these symptoms. However, it does not prevent seizures, elevated blood pressure, or delirium, and other medications are necessary for this.
