Bupropion for fatigue and as a tumor necrosis factor-α lowering agent in primary biliary cirrhosis

Primary biliary cirrhosis (PBC) is a chronic cholestatic disease which can often be severe, progressive and necessitate liver transplantation. The cause of PBC is not known, and treatments other than liver transplantation are often not effective. Among the more common and troublesome symptoms of PBC is fatigue. The etiology of fatigue in PBC is not well-understood, and there is no known treatment for it. Here, we suggest that for a number of reasons that the safe and commonly used oral antidepressant bupropion might be effective for fatigue in PBC: (1) increased monoaminergic and dopaminergic tone to combat fatigue, (2) treatment of concomitant depression, (3) in general for PBC as a tumor necrosis factor-α (TNF) lowering agent, if TNF is eventually found to play a role in PBC pathogenesis.
