Which is true about narcotics such as morphine and obstructive sleep apnea symptoms?

• A. They cure OSA symptoms
• B. They have no effect on OSA symptoms
• C. They exacerbate OSA symptoms
• D. They cause OSA symptoms to disappear during the day

Answer: (C)

Opioids like morphine can worsen obstructive sleep apnea because they depress the brain’s respiratory drive and relax the muscles of the upper airway. During sleep, OSA happens when the pharyngeal dilator muscles don’t keep the airway open, causing repeated obstructions. Morphine blunts the response to rising CO2, slows breathing, and reduces the tone of the muscles that keep the airway open. This makes airway collapse more likely and lengthens apneas, leading to more nocturnal hypoxemia and fragmented sleep. So these drugs do not cure OSA; they typically exacerbate its symptoms. They also don’t cause daytime symptoms to disappear; rather, they can worsen daytime sleepiness due to poorer sleep quality and oxygenation. If a patient with OSA requires analgesia, use non-opioid options when possible, or the lowest effective opioid dose with close respiratory monitoring and consideration of alternative strategies or airway support as needed.
