Oxycodone is increasingly being used in combination with pregabalin. Pregabalin use is prevalent in opioid-dependent individuals. A high number of deaths caused by the co-use of gabapentinoids and opioids occur. It is not known whether pregabalin affects concentrations of oxycodone or morphine in the central nervous system. ⋯ Pregabalin potentiated antinociceptive and sedative effects of oxycodone and morphine in acute nociception. Co-administration of pregabalin with the opioids did not affect the brain concentrations of oxycodone or morphine. Pregabalin did not prevent morphine tolerance.

Randomized Controlled Trial Multicenter Study Comparative Study
Capsaicin 8% patch versus oral pregabalin in patients with peripheral neuropathic pain.
Clinical trials have not yet compared the efficacy of capsaicin 8% patch with current standard therapy in peripheral neuropathic pain (PNP). ⋯ The capsaicin 8% patch provided non-inferior pain relief to an optimized dose of pregabalin in PNP, with a faster onset of action, fewer systemic side effects and greater treatment satisfaction.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of nicoboxil/nonivamide ointment for the treatment of acute pain in the low back - A randomized, controlled trial.
Until now, nonivamide/nicoboxil ointment has not been tested in a randomized trial for the treatment of acute non-specific low back pain. ⋯ Nicoboxil/nonivamide ointment is an effective, well-tolerated medication for the treatment of acute non-specific low back pain.

Randomized Controlled Trial Multicenter Study
Factors associated with pain and disability reduction following exercise interventions in chronic whiplash.
Some studies support the prescription of exercise for people with whiplash-associated disorders (WAD); however, the response is highly variable. Further research is necessary to identify factors which predict response. ⋯ Factors associated with treatment response after exercise interventions differ in the short and long term and differ depending on whether neck pain or disability is considered as the primary outcome. Participation in a neck-specific exercise intervention, in contrast to general physical activity, was the only factor that consistently indicated higher odds of treatment success. These results support the prescription of neck-specific exercise for individuals with chronic WAD.

Pain and sensory abnormalities are present in a large proportion of Parkinson disease (PD) patients and have a significant negative impact in quality of life. It remains undetermined whether pain occurs secondary to motor impairment and to which extent it can be relieved by improvement of motor symptoms. The aim of this review was to examine the current knowledge on the mechanisms behind sensory changes and pain in PD and to assess the modulatory effects of motor treatment on these sensory abnormalities. ⋯ However, there is no direct correlation between sensory/pain changes and motor improvement, suggesting that motor and non-motor symptoms do not necessarily share the same mechanisms. Whether dopamine and DBS have a real antinociceptive effect or simply a modulatory effect in pain perception remain uncertain. These data may provide useful insights into a mechanism-based approach to pain in PD, pointing out the role of the dopaminergic system in pain perception and the importance of the characterization of different pain syndromes related to PD before specific treatment can be instituted.
