Hepatobiliary pruritus: what are effective treatments?

Pruritus is a common symptom in patients with hepatobiliary disease. Numerous treatments have been attempted. We review published therapeutic trials for hepatobiliary pruritus and utilize statistical analysis to evaluate treatment results. Randomized placebo-controlled studies show cholestyramine, rifampin, naloxone, S-adenosylmethionine, prednisolone, and propofol to be effective. Suggestions for future studies of the treatment of hepatobiliary puruitus are proposed.
