Abstract
The recurrence rates of pruritus after stopping nalfurafine hydrochloride are unknown in chronic liver disease. A prospective confirmatory trial was carried out to determine the recurrence rates of pruritus after cessation of nalfurafine hydrochloride in chronic liver disease. After pretreatment with nalfurafine hydrochloride for 4weeks or more, 15 consecutive Japanese patients, who confirmed the improvement of pruritus (decrease in the visual analogue scale (VAS) of ≥50mm), were enrolled in the present study. Patients were classified to the continuous group (continuation of nalfurafine hydrochloride for 4weeks) or the discontinuous group (cessation of nalfurafine hydrochloride) at the time of consent to study protocol, by self-determination. The recurrence rates (increase in VAS of ≥25mm after stopping nalfurafine hydrochloride) were 100% (5 of 5 patients) and 0% (0 of 10) in the discontinuous and continuous groups, respectively. In the discontinuous group, 3 patients selected retreatment with nalfurafine hydrochloride as salvage therapy, and they generally recovered to the levels of VAS at the discontinuation of treatment. The present prospective trial showed the high recurrence rates of pruritus after the stop of nalfurafine hydrochloride in chronic liver disease.
