Alkaline phosphatase and bilirubin remained normal throughout the hospital course. Gabapentin was the only new medication added before the onset of the elevation of liver enzymes, thus it was discontinued.

How does gabapentin calm nerves?

Neurotransmitters are chemicals that carry signals between nerve cells. The GABA neurotransmitter can help slow down neurons firing in the brain. Gabapentin works in a similar way; it can help quiet the brain and decrease pain transmission in your nerves.
