Outcome Measures

Primary Outcomes (1)

  • The change in ventilation (L) per minute during stable sleep with morphine versus placebo.

    The primary outcome, determining the change in ventilation in liters per minute, will be analyzed on both subpopulations (controls and people with obstructive sleep apnea) using generalized linear mixed models with treatment, period and sequence as fixed effects and a random effect of participant nested within sequence.

    From enrollment to the end of treatment at 6 weeks.

Study Arms (2)

Morphine

ACTIVE COMPARATOR
Drug: Morphine p.o.

Placebo

PLACEBO COMPARATOR
Drug: Placebo

Interventions

Morphine 50mg PO will be given on sleep study night.

Morphine

Placebo will be given on the sleep study night.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy controls: Apnea Hypopnea Index (AHI) \< 5 events/hr on in-laboratory PSG within 3 months of enrollment
  • OSA group: AHI \> 10 events/hr on in-laboratory PSG within 3 months of enrollment; treated or untreated.

You may not qualify if:

  • Sleep disordered breathing or respiratory disorders (other than OSA in the OSA group), such as central sleep apnea (\>50% of respiratory events scored as central), chronic hypoventilation/hypoxemia (awake SaO2 \< 92% by oximetry) due to chronic obstructive pulmonary disease or other respiratory conditions.
  • Other sleep disorders: periodic limb movements (periodic limb movement index \> 20/hr), narcolepsy, or parasomnias.
  • Any unstable major medical condition.
  • Medications expected to stimulate or depress respiration (including other opioids taken at home, barbiturates, benzodiazepines, doxapram, almitrine, theophylline, 4-hydroxybutanoic acid).
  • History of allergy to lidocaine or oxymetazoline.
  • Contraindications for morphine, including:
  • allergy to morphine or opioids
  • chronic obstructive pulmonary disease, asthma, or other significant respiratory disorders
  • kidney or liver dysfunction, as this can affect the metabolism and excretion of morphine, leading to increased risk of toxicity.
  • women who are pregnant or breastfeeding will be excluded due to potential risks to the fetus or infant.
  • history of substance abuse, particularly opioid abuse, will be excluded to prevent potential misuse or relapse.
  • current use of central nervous system depressants.
  • recent head injury, brain tumors, or other conditions leading to increased intracranial pressure.
  • unstable heart disease, particularly those with risk factors for or a history of heart rhythm disorders.
  • epilepsy or a history of seizures, as morphine can lower the seizure threshold.
  • +3 more criteria
