Fentanyl-Induced Respiratory Depression and Locomotor ... - eNeuro

Opioid drugs act on μ-opioid receptors (MORs) in spinal and brainstem regions involved in pain, but also on regions regulating breathing (Stein, ...

Opioids depress breathing through two small brainstem sites - PMC

Here we show that two small brainstem sites are sufficient to rescue opioid induced respiratory depression in vivo. Between them, the preBötC is the critical ...

Current research in pathophysiology of opioid-induced respiratory ...

Respiratory depression (RD) is the primary cause of death due to opioids. Opioids bind to mu (µ)-opioid receptors (MORs) encoded by the MOR gene Oprm1, widely ...

Frontiers | Opioids, sleep, analgesia and respiratory depression

Despite challenges to resolve the neural substrates of respiratory malfunctions during opioid overdose, two main areas, the pre-Bötzinger ...

(PDF) Opioids depress breathing through two small brainstem sites

We find the critical brain site is the preBötzinger Complex, where the breathing rhythm originates, and use genetic tools to reveal that just 70-140 neurons in ...

Opioids and the control of respiration - ScienceDirect.com

The degree of respiratory depression varies between drugs, but there are currently no opioids available that are devoid of respiratory side-effects. Although ...

Understanding and countering opioid‐induced respiratory depression

Therefore, opioids compromise not only cortical and sensory drive but also the brainstem neurons that control breathing when arousal is low. Not ...

Opioids depress breathing through action on two brainstem sites

Here, I identify two primary changes to breathing after administering opioids. These changes implicate the brainstem's breathing circuitry.

Opioids and the control of respiration | BJA - Oxford Academic

Respiratory depression limits the use of opioid analgesia. Although well described clinically, the specific mechanisms of opioid action on respiratory control ...

Opioids Depress Cortical Centers Responsible for the Volitional ...

Although opioids are known to inhibit brainstem respiratory activity, their effects on cortical areas that mediate respiration are less well ...

Neural basis of opioid-induced respiratory depression and its rescue

Here, we show that neurons within the lateral parabrachial nucleus that express the µ-opioid receptor (PBLOprm1 neurons) are involved in OIRD ...

Fentanyl effects on respiratory neuron activity in the dorsolateral pons

Opioids suppress breathing through actions in the brainstem, including respiratory-related areas of the dorsolateral pons, which contain ...

Opioid Overdose: Limitations in Naloxone Reversal of Respiratory ...

When individuals overdose on a potent opioid, their breathing will initially become irregular, then cyclic, and after a period of gasping will become apneic.
