Limited research exists to support the extrapolation of the analgesic efficacy of pregabalin from one neuropathic pain condition to another. This retrospective analysis evaluated similarities in the efficacy of pregabalin for treating neuropathic pain associated with post-herpetic neuralgia (PHN), diabetic peripheral neuropathy (DPN), and spinal cord injury (SCI) in a Japanese population, as a basis for considering the extrapolation of these data to other neuropathic pain conditions. ⋯ NCT00394901, NCT00553475, NCT00407745, NCT00424372, NCT00553280, NCT01202227.

Review Meta Analysis
Umeclidinium Plus Vilanterol Versus Placebo, Umeclidinium, or Vilanterol Monotherapies for Chronic Obstructive Pulmonary Disease: A Meta-Analysis of Randomized Controlled Trials.
The role of umeclidinium plus vilanterol as a combination therapy for chronic obstructive pulmonary disease (COPD) has not yet been clearly defined. ⋯ Compared with the other three groups, i.e. placebo, umeclidinium and vilanterol, umeclidinium plus vilanterol improves lung function and quality of life in patients with COPD, reduces the use of albuterol, and does not increase the incidence of adverse events and serious adverse events.

Hydrocodone bitartrate extended-release (Hysingla® ER; referred to hereafter as hydrocodone ER) was the first single-entity hydrocodone formulation recognized by the US FDA as having abuse-deterrent properties. It is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Once-daily oral hydrocodone ER provides consistent plasma hydrocodone concentrations and sustained analgesia over the 24-h dosing interval. ⋯ Hydrocodone ER was generally well tolerated, with a safety profile consistent with that seen with other μ-opioid analgesics. However, like other opioids, it is associated with risks of addiction, abuse/misuse and serious adverse events (AEs), including respiratory depression, withdrawal, physical dependence and overdose. Although large postmarketing studies are needed to determine whether the abuse-deterrent properties of hydrocodone ER result in meaningful reductions in abuse, misuse and related adverse clinical outcomes, current evidence indicates that hydrocodone ER is a useful treatment option for patients with chronic pain.
