Increased opioidergic neurotransmission in the brain appears to contribute to the pruritus that complicates cholestasis and certain non-cholestatic chronic liver diseases. Opiate antagonists have been shown to decrease scratching activity in patients with the pruritus of cholestasis. ⋯ The infusion rate of naloxone should initially be very low; it should be increased gradually and stopped when a rate known to be associated with opioid antagonist effects has been attained. Oral therapy with an opiate antagonist can then be initiated.
