Opioid medications are an important tool in the management of pain and have been used in clinical practice for centuries. However, due to the highly addictive nature of this class of medications coupled with the life-threatening side effect of respiratory depression, opioid misuse has become a significant public health crisis worldwide. Children and adolescents are at risk for opioid misuse, and early detection is imperative to facilitate treatment and improve outcomes. This review will address the current state of opioid misuse and treatment in children and adolescents in the United States.

Understanding the molecular biology of opioid analgesia is essential for its proper implementation and mechanistic approach to its modulation in order to maximize analgesia and minimize undesired effects. By appreciating the molecular mechanisms intrinsic to opioid analgesia, one can manipulate a molecular target to augment or diminish a specific effect using adjuvant drugs, select an appropriate opioid for opioid rotation or define a molecular target for new opioid drug development. In this review, we present the cellular and molecular mechanisms of opioid analgesia and that of the associated phenomena of tolerance, dependence, and hyperalgesia. The specific mechanisms highlighted are those that presently can be clinically addressed.

Children represent a patient demographic composed of multiple, unique subpopulations differentiated by rapidly changing age-related physiology, which includes the means of metabolizing opioids. Opioids are an important part of the pharmacological treatment of both acute and chronic pain. In both clinical medicine and clinical research, it is necessary to understand the differences in drug handling by age cohort in order to appropriately dose children to effect, and to avoid exacerbating deleterious adverse events with potentially grave sequelae. ⋯ Understanding how these variables change the pharmacokinetics and pharmacodynamics of each opioid is critical to the successful and safe management of pain in children.

The increase in opioid-related deaths in the United States (and other countries) has prompted a national debate in medicine about the appropriateness of opioids for the treatment of acute and chronic pain, and specifically in children, if medical opioid use causes or increases the risk of opioid use disorder (OUD) later in life. Some in the medical community and in government advocate withholding opioids from children after an arbitrary number of days of treatment, regardless of diagnosis. Here, I argue that opioid experimentation and misuse is no more common in children and adolescents today than 2 or 3 decades ago, that there is no compelling evidence that appropriate medical use of opioids leads to OUD, and that the epidemic of inadequately treated pain in children remains the more compelling issue.

The entire field of medicine, not just anesthesiology, has grown comfortable with the risks posed by opioids; but these risks are unacceptably high. It is time for a dramatic paradigm shift. ⋯ Furthermore, there are a myriad of alternative analgesic strategies that provide superior analgesia, decrease recovery time, and have fewer side effects and risks associated with their use. In this article the negative consequences of opioid use for pain, appropriate alternatives to opioids for analgesia, and the available evidence in pediatric populations for both are described.
