Solving the Opioid Crisis: Respiratory Depression by Opioids as Critical Endpoint.

Summary of "Solving the Opioid Crisis: Respiratory Depression by Opioids as Critical Endpoint."

Opioid overdose is due to misuse of prescription pain killers such as oxycodone, as well as misuse of street drugs like heroin or fentanyl. Opioid overdoses are responsible for the deaths of over 50,000 persons annually in North America. Opioid drugs are highly addictive and can lead to respiratory depression and death. Although opioid addiction is a critical health issue, the morbidity and mortality associated with opioid overdoses are due to their respiratory depressant side-effects, and not addiction per se. Even though respiratory depression and complete respiratory arrest are the major causes of mortality with opioid overdose, there is currently a serious knowledge gap in our understanding of the underlying mechanisms of opioid pain relief and respiratory depression by opioids, and how these mechanisms differ from each other. We propose that there should be a greater research focus on these mechanisms in order to help develop safer opioid pain therapies with reduced respiratory side-effects. Here, we provide a brief overview of current research investigating the neural and molecular mechanisms underlying opioid-induced respiratory depression and analgesia. We focus our attention on the neural circuits of analgesia and respiratory depression, and the molecular pathways regulating opioid inhibition. We highlight the challenges in identifying distinct mechanisms that could be targeted to reduce respiratory depression without altering opioid analgesia. In conclusion, a better understanding of the underlying mechanisms linking pain relief with control of breathing is essential to identify pain therapies with minimal or no respiratory side-effects.

Medical and Biotech [MESH] Definitions

An opioid antagonist with properties similar to those of NALOXONE; in addition it also possesses some agonist properties. It should be used cautiously; levallorphan reverses severe opioid-induced respiratory depression but may exacerbate respiratory depression such as that induced by alcohol or other non-opioid central depressants. (From Martindale, The Extra Pharmacopoeia, 30th ed, p683)

Cell membrane proteins that bind opioids and trigger intracellular changes which influence the behavior of cells. The endogenous ligands for opioid receptors in mammals include three families of peptides, the enkephalins, endorphins, and dynorphins. The receptor classes include mu, delta, and kappa receptors. Sigma receptors bind several psychoactive substances, including certain opioids, but their endogenous ligands are not known.

A delta-selective opioid (ANALGESICS, OPIOID). It can cause transient depression of mean arterial blood pressure and heart rate.

Disorders related or resulting from abuse or mis-use of opioids.

Health care provided to a critically ill patient during a medical emergency or crisis.
