Patients were given the placebo (n=20) or Nalterxone 50 mg (n=18) for a two-week period. During the study, pruritus scores were distinguished by a visual analogue scale (VAS) system and recorded in patients questionnaires three times, at the start of study, after 1 week, and after 2 weeks
Results: In the both groups VAS score were decreased, although Naltrexon was more effective than placebo in decreasing the VAS scores, both in 1st week week (P < 0.005) and 2nd week (P< 0.001).
