<p>Eslicarbazepine acetate is converted into the anti-epileptic medicine Eslicarbazepine in the body. Epilepsy is caused by excessive electrical activity in the brain. For electrical impulses to travel along nerves there needs to be a rapid movement of sodium into the nerve cells. Eslicarbazepine acetate is thought to work by blocking &lsquo;voltage-gated sodium channels&rsquo;, which stops sodium entering the nerve cells. This reduces the activity of the nerve cells in the brain, reducing the intensity and the number of seizures.</p>
