Brief summary
The Summary of product characteristics (SmPC) for QUTENZA advises that topical anaesthetic is applied prior to the application of QUTENZA. This is a multi-center, randomized, assessor-blinded study which will investigate the use of an oral analgesic as an alternative form of pre-treatment for QUTENZA.
Detailed description
All patients will be treated with QUTENZA for 60 minutes. Patients will be randomized to one of two arms- application of topical anaesthetic (lidocaine cream) or an oral analgesic (tramadol oral tables) prior to application of QUTENZA. Patients will be followed up for 7 days to monitor pain scores and tolerability.
