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.

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.

Randomized Controlled Trial
Exposure-Efficacy Analyses of Ombitasvir, Paritaprevir/Ritonavir with Dasabuvir ± Ribavirin in HCV Genotype 1-Infected Patients.
The three-direct-acting antiviral (DAA) combination regimen of ombitasvir, paritaprevir (coadministered with ritonavir [paritaprevir/ritonavir], and dasabuvir (the 3D regimen) ± ribavirin for treatment of HCV genotype 1-infected patients demonstrated efficacy and safety in Phase II and Phase III clinical trials. The relationships between the steady-state exposure (area under the concentration-time curve at steady state and trough concentration at steady state) of the three DAAs and ribavirin with sustained virologic response at 12 weeks after treatment (SVR12) following administration of the 3D regimen in six Phase II/III studies were examined. ⋯ The results of these analyses indicate that the doses selected for the 3D regimen were optimal, achieving high SVR12 rates across the range of exposures observed in the Phase III studies.

Type 2 diabetes mellitus (T2DM) is a chronic progressive disease that has been spread worldwide over the past three decades and associated with increased morbidity and mortality resulting in considerable socioeconomic implications for national healthcare systems. Effective management of disease is highly needed ensuring patients receive the best possible care within the available budget. The objective of this study was to evaluate the long-term cost-effectiveness of dapagliflozin, a sodium-glucose co-transporter-2 (SGLT-2) inhibitor, compared with a sulfonylurea (SU) or a dipeptidyl-peptidase-4 inhibitor (DPP-4i), when added to metformin, in T2DM patients inadequately controlled on metformin alone in Greece. ⋯ Dapagliflozin in combination with metformin was shown to be a cost-effective treatment alternative for patients with T2DM whose metformin regimen does not provide sufficient glycemic control in a Greek healthcare setting.

Based on earlier literature, etoricoxib may have a delayed analgesic effect in postoperative setting when analgesic efficacy of nonselective nonsteroidal anti-inflammatory drug dexketoprofen is rapid. This may be caused by slow penetration of etoricoxib into the central nervous system (CNS). Therefore we decided to determine the plasma and cerebrospinal fluid (CSF) pharmacokinetics and pharmacodynamics of dexketoprofen and etoricoxib in patients with hip arthroplasty. ⋯ Dexketoprofen and etoricoxib entered the CNS readily, already at 30 min after administration dexketoprofen was detected in the CSF in most subjects and etoricoxib after 60 min. A single dose of dexketoprofen and etoricoxib provided a similar anti-inflammatory and analgesic response after major orthopaedic surgery.
