Primary Outcome Measures:
  • Severity of pruritus [ Time Frame: one week ] [ Designated as safety issue: No ]
    The primary endpoint is the severity of pruritus as measured on the visual analogue scale.


Secondary Outcome Measures:
  • Quality of life [ Time Frame: one week ] [ Designated as safety issue: No ]
    The secondary endpoint is the quality of life as measured on the Dermatology Quality of Life Index (DLQI).


Estimated Enrollment: 16
