Sleep among opioid users

Area of Science:

• Sleep Medicine
• Pharmacology
• Respiratory Medicine

Background:

• Opioid analgesic use has surged over the last 20 years for acute and chronic pain.
• Emerging evidence links chronic opioid therapy to sleep-related breathing disorders (SRBDs).
• Central sleep apnea (CSA), including periodic and nonperiodic patterns, is a key SRBD associated with opioid use.

Purpose of the Study:

• To review the current literature on the impact of acute and chronic opioid use on sleep.
• To examine the relationship between opioid use and sleep-disordered breathing.
• To summarize evidence regarding treatment strategies for opioid-induced SRBDs.

Main Methods:

• Literature review of studies on opioid use, sleep, and breathing disorders.
• Analysis of current research on the pathogenesis of opioid-related SRBDs.
• Synthesis of data on clinical significance and management of these conditions.

Main Results:

• Opioid use, both acute and chronic, demonstrably affects sleep architecture and respiratory patterns.
• A significant association exists between chronic opioid therapy and the development or exacerbation of central sleep apnea.
• Understanding of the precise mechanisms and optimal treatments for opioid-induced SRBDs remains limited.

Conclusions:

• Opioid-induced sleep-disordered breathing, particularly central sleep apnea, is an under-recognized complication of pain management.
• Further research is crucial to elucidate the pathogenesis and establish effective treatment guidelines.
• Clinicians should consider screening for SRBDs in patients on chronic opioid therapy.
