Opioid analgesics are commonly and increasingly prescribed by physicians for the management of chronic pain. However, strong evidence supports the need for strategies that reduce opioid use. The objective of this review is to outline limitations associated with opioid use and discuss therapeutic techniques that can be adopted to optimize the use of opioids in the management of chronic nonmalignant pain. ⋯ Appropriate patient selection through identification of risk factors, urine drug testing, and access to prescription monitoring programs has been shown to effectively improve care. Structured opioid therapy in a multimodal platform, including use of a low initial dose, prescription of alternative non-opioid analgesics including non-steroidal anti-inflammatory drugs and acetaminophen, as well as development of written care agreements to individualize and guide therapy has also been shown to improve patient outcomes. Implementation of opioid allocation strategies has the potential to encourage appropriate opioid use and improve patient care.

A growing number of studies have shown that opioid craving (i.e., the perceived need or desire to consume opioids) is one of the strongest determinants of prescription opioid misuse in patients with chronic pain prescribed opioid therapy. To date, however, the factors that are associated with craving in patients with pain remain largely unexplored. Based on previous research, there is reason to believe that catastrophizing might be associated with heightened opioid craving. ⋯ Our preliminary findings provide valuable new insights into the determinants of craving in patients with pain. The finding that catastrophizing was associated with craving even after controlling for a host of demographic, psychological, medical, and medication regimen variables is particularly striking, and raises questions concerning the factors that underlie the association between catastrophizing and craving in patients prescribed opioid therapy.

ReviewSite and mechanism of morphine tolerance in the gastrointestinal tract.
Opioid-induced constipation is a major clinical problem. The effects of morphine, and other narcotics, on the gastrointestinal tract persist over long-term use thus limiting the clinical benefit of these excellent pain relievers. The effects of opioids in the gut, including morphine, are largely mediated by the μ-opioid receptors at the soma and nerve terminals of enteric neurons. ⋯ Here, we review the mechanisms by which tolerance develops in the small but not the large intestine. The regional differences lie in the signaling and regulation of the μ-opioid receptor in the various segments of the gastrointestinal tract. The differential role of β-arrestin2 in tolerance development between central and enteric neurons defines the potential for therapeutic approaches in developing ligands with analgesic properties and minimal constipating effects.

The aim of this study was to determine the frequency and nature of physician, nurse, and pharmacist verbal counseling at the time of a new prescription for an opioid-acetaminophen containing medication as recalled by patients. ⋯ Patients infrequently recall counseling from providers on topics that are important to prevent harm from opioid-acetaminophen prescriptions. Future patient-centered clinical research should target identifying optimal strategies to convey these critical messages.

Due to rising rates of opioid addiction and overdose among individuals on chronic opioid therapy, aberrant drug-related behaviors (ADRBs) are an important and challenging issue. Our objective was to qualitatively investigate the documentation of ADRBs in the medical record. ⋯ The impact of including emotional language in the medical record is unknown. Development of instruments that can be used to facilitate ADRB documentation, as well as evidence-based approaches to addressing ADRBs, is needed.
