Responses to pharmacotherapy for acute and chronic pain are highly variable, and efficacy is often compromised by some form of toxicity. To increase our understanding of complexities of pharmacotherapy, the authors discuss an approach to identify analgesic responder subgroups and predictors of response. Additionally, analgesic efficacy and toxicity were combined in a single risk-benefit index (utility function) to quantify the probability of side effects in high- vs low-analgesic responders. ⋯ An important observation was that, irrespective of dose, low-analgesic responders to fentanyl had a greater probability of respiratory depression than analgesia while the reverse was true for high-analgesic responders. These data show dissociation between 2 μ-opioid end-points and explain the danger of treating poor analgesic responders with increasingly higher opioid doses. Apart from being valuable in drug development programs, the outlined approach can be used to determine the choice of drug and dose in the treatment of pain in patients with potent and toxic analgesics.

Intravenous nonopioid analgesic drugs in chronic low back pain patients on chronic opioid treatment: A crossover, randomised, double-blinded, placebo-controlled study: Retraction.
The authors of the 2014 article "Intravenous nonopioid analgesic drugs in chronic low back pain patients on chronic opioid treatment: A crossover, randomised, double-blinded, placebo-controlled study" wish to retract the article as Dr Kozek-Langenecker did not consent to its submission and publication.

Chronic pain affects both psychological and physical functioning, and is responsible for more than $60 billion in lost productivity annually in the United States. Although previous studies have demonstrated racial disparities in opioid treatment, there is little evidence regarding disparities in treatment of chronic noncancer pain (CNCP) and the role played by physician specialty in these disparities. ⋯ Our findings suggest that, in our study population, black beneficiaries with CNCP are less likely than whites to fill prescriptions for opioid analgesics as a function of their provider's specialty. Although race-based differences in patients filling opioid prescriptions have been noted in previous studies, this is the first study that clearly demonstrates these disparities by provider specialty.

Despite recent advances in the knowledge of pain mechanisms and pain management, postoperative pain continues to be a problem. Inadequately managed postsurgical pain has both clinical and economic consequences such as longer recovery times, delayed ambulation, higher incidence of complications, increased length of hospital stay, and potential to develop into chronic pain. Generally, opioids are the mainstay option for pain management in patients with moderate-to-severe postsurgical pain; however, opioids have significant side effects and have abuse potential. ⋯ Utilizing a multi-modal approach may result in a greater reduction in pain vs. single therapies in addition to minimizing opioid use, thus reducing opioid related side effects. However, not all approaches may be effective for all types of patients and not all analgesics may be a viable option for outpatient settings, ambulatory surgery, or the fast-track surgical procedures. In this report, we present a review of the literature with a focus on intranasal ketorolac in order to provide a timely update regarding past, present, and future multi-modal treatment options for postoperative pain.
