Comparative StudyComparison of pain outcomes between two anti-GD2 antibodies in patients with neuroblastoma.
Addition of anti-GD2 antibody ch14.18 to the treatment of neuroblastoma has improved outcomes. The most common side effect of ch14.18 is neuropathic pain, which may in part be complement-mediated. Hu14.18K322A is a humanized anti-GD2 antibody designed to diminish complement activation and induce less pain. We compare the pain outcomes in patients treated with ch14.18 and those treated with hu14.18K322A, and explore dose-dependent relationships between pain scores, opioid requirements, and complement levels in patients treated with hu14.18K322A. ⋯ In this retrospective analysis, hu14.18K322A induced less pain than ch14.18 based on opioid requirements.

ReviewAbuse-deterrent formulations: part 1 - development of a formulation-based classification system.
Strategies have been implemented to decrease the large proportion of individuals misusing abusable prescription medications. Abuse-deterrent formulations (ADFs) have been grown to incorporate many different technologies that still lack a systematic naming and organizational nomenclature. Without a proper classification system, it has been challenging to properly identify ADFs, study and determine common traits or characteristics and simplify communication within the field. ⋯ Drug products using opioid antagonists and aversive agents have been seen over the past few decades to discourage primarily overuse and injection. However, innovation in formulation development has introduced products capable of deterring multiple forms of tampering and abuse. Often, this is accomplished using known excipients and manufacturing methods that are repurposed to prevent crushing, extraction and syringeability.

Benzodiazepines (BZDs) are commonly used by chronic pain patients, despite limited evidence of any long-term benefits and concerns regarding adverse events and drug interactions, particularly in older patients. This article aims to: describe patterns of BZDs use; the demographic, physical, and mental health correlates of BZD use; and examine if negative health outcomes are associated with BZD use after controlling for confounders. ⋯ CNCP patients using BZDs daily represent a high-risk group with multiple comorbid mental health conditions and higher rates of emergency health care use. The high prevalence of BZD use is inconsistent with guidelines for the management of CNCP or chronic mental health conditions.

Impact of abuse-deterrent OxyContin on prescription opioid utilization.
We quantified the degree to which the August 2010 reformulation of abuse-deterrent OxyContin affected its use, as well as the use of alternative extended-release and immediate-release opioids. ⋯ The market debut of abuse-deterrent OxyContin was associated with declines in its use after accounting for the simultaneous contraction of the generic extended-release oxycodone market. Further scrutiny into the effect of abuse-deterrent formulations on medication use and health outcomes is vital given their popularity in opioid drug development.

Single- and multiple-dose pharmacokinetics of a hydrocodone bitartrate extended-release tablet formulated with abuse-deterrence technology in healthy, naltrexone-blocked volunteers.
A hydrocodone extended-release (ER) formulation was developed to provide sustained pain relief with twice-daily dosing. Developed using the CIMA abuse-deterrence technology platform (CIMA Labs Inc, Brooklyn Park, Minnesota), this formulation also provides resistance against rapid release of hydrocodone when tablets are comminuted and resistance against dose dumping when tablets are taken with alcohol. Two open-label studies evaluated hydrocodone ER pharmacokinetics (PK) after single- and multiple-dose administration in healthy, naltrexone-blocked subjects. ⋯ The PK profile of hydrocodone ER was qualitatively similar after single- and multiple-dose administration. The steady-state profile demonstrated sustained exposure with limited swing and fluctuation. Single and multiple doses of hydrocodone ER (45 and 90 mg) were generally well tolerated in healthy subjects receiving naltrexone; however, exposure to naltrexone may have confounded the interpretation of safety findings.
