A Study to Compare QUTENZA With Pregabalin for the Treatment of Peripheral Neuropathic Pain (PNP) After 8 Weeks of Treatment

This study is comparing the efficacy and tolerability of Qutenza with that of pregabalin in patients suffering from peripheral neuropathic pain. Treatment allocation will be to one of these treatments and the duration of the study will be about 10 weeks (assuming that from screening to treatment allocation takes 2 weeks). Participants will be asked to complete questionnaires about various aspects relating to their condition throughout the study. This study will include subjects suffering from Postherpetic Neuralgia, Peripheral Nerve Injury or Non Diabetic peripheral polyneuropathy.
