Efficacy and safety of pregabalin in treatment refractory patients with various neuropathic pain entities in clinical routine.

Aims: Conventional approaches to the management of neuropathic pain (NeP) often yield unsatisfactory results. We aimed to investigate pregabalin, a gamma-aminobutyric acid (GABA)-analogue, in a wide range of pregabalin naive patients with treatment refractory NeP.

Methods: Investigator-initiated, 4-week, open, prospective multicentre study in tertiary care.
