Primary Outcome Measures

Name	Time	Method
Main Objective: Valutare se l aggiunta di buprenorfina TDS alla terapia in corso determina un soddisfacente controllo del dolore definito come riduzione 30 dell intensita del dolore valutato con la VAS in pazienti affetti da dolore neuropatico cronico che non ha risposto in modo soddisfacente alla terapia iniziale. La tollerabilita di buprenorfina TDS sara valutata in tutti i pazienti, per l intera durata dello studio.;Secondary Objective: To verify if an adequate pain control can be obtained with buprenorphine TDS monotherapy,to define the optimal dose schedule and to get information on the possible occurrence of withdrawal symptoms and/or pain rebound during the follow up period immediately subsequent to BUP TDS treatment cessation.;Primary end point(s): Pain control reduction 30 of pain severity at VAS
