Randomized Controlled Trial Multicenter Study
Hydromorphone extended release for neuropathic and non-neuropathic/nociceptive chronic low back pain: a post hoc analysis of data from a randomized, multicenter, double-blind, placebo-controlled clinical trial.
The aim of this study was to determine the efficacy and tolerability of hydromorphone extended release (ER) in patients with chronic low back pain (LBP) with or without a neuropathic component. ⋯ The results of this study indicate that hydromorphone ER is efficacious and generally well tolerated in the management of patients with non-neuropathic and neuropathic chronic LBP.
