Study: Oral THC Administration Mitigates Sleep Apnea

“The oral administration of synthetic THC reduces symptoms of sleep apnea, according to clinical trial data published online in the scientific journal Frontiers in Psychiatry. Sleep apnea is a medical disorder characterized by frequent interruptions in breathing of up to ten seconds or more during sleep. The condition is associated with numerous physiological disorders, including fatigue, headaches, high blood pressure, irregular heartbeat, heart attack and stroke.

Investigators at the University of Illinois at Chicago, Department of Medicine assessed the safety, tolerability, and efficacy of dronabinol (oral THC in sesame seed oil) in 17 subjects with Obstructive Sleep Apnea.

Oral THC administration was associated with a significant change in Apnea Hypopnea Index over a 21-day period. Authors further determined dronabinol treatment to be safe and well tolerated.

They concluded, “These findings should be confirmed in a larger study in order to identify sub-populations with OSA that may benefit from cannabimimetic pharmacologic therapy.”

Dronabinol, marketed under the trade name Marinol, is FDA-approved to treat nausea and vomiting caused by chemotherapy.”

“A medical disorder characterized by frequent interruptions in breathing of up to 10 seconds or more during sleep, sleep apnea, is associated with many physiological disorders, including fatigue, headaches, high blood pressure, irregular heartbeat, heart attack, and stroke…

In the June issue of the American Academy of Sleep Medicine Journal, researchers at the University of Illinois, Department of Medicine reported that sleep apnea in rats that received cannabinoids (natural chemicals of cannabis) was deleted. Doses of delta-9-THC and stabilized polyamide breathing during sleep and blocked serotonin-induced exacerbation of sleep apnea. Many patients who have used the ratio of medical cannabis improved sleep quality and less fatigue the next day.”

Functional role for cannabinoids in respiratory stability during sleep.

“Serotonin, acting in the peripheral nervous system, can exacerbate sleep-related apnea, and systemically administered serotonin antagonists reduce sleep-disordered respiration in rats and bulldogs. Because cannabinoid receptor agonists are known to inhibit the excitatory effects of serotonin on nodose ganglion cells, we examined the effects of endogenous (oleamide) and exogenous (delta9-tetrahydrocannabinol; delta9THC) cannabimimetic agents on sleep-related apnea…

Our data show that delta9THC and oleamide each stabilized respiration during all sleep stages… This observation suggests an important role for endocannabinoids in maintaining autonomic stability during sleep…

CONCLUSIONS:

This study demonstrates potent suppression of sleep-related apnea by both exogenous and endogenous cannabinoids. These findings are of relevance to the pathogenesis and pharmacological treatment of sleep-related breathing disorders.”

Circulating anandamide and blood pressure in patients with obstructive sleep apnea.

” OBJECTIVE: Obstructive sleep apnea chronically increases blood pressure through sympathetic nervous system activation. In animals, hypertension and sympathetic activity are restrained by cannabinoid receptor activation. Therefore, we hypothesized that increased blood pressure in patients with obstructive sleep apnea is associated with increased circulating endocannabinoid concentrations.

 

CONCLUSION: Obstructive sleep apnea patients show positive correlations between blood pressure and venous anandamide concentrations independent of confounding factors. Our data suggest a previously not recognized role of the endocannabinoid system for blood pressure regulation in patients with high risk for hypertension and cardiovascular disease.”

Circulating endocannabinoids and N-acyl-ethanolamides in patients with sleep apnea–specific role of oleoylethanolamide.

“OBJECTIVE:  The endocannabinoid system promotes diverse effects on fat and glucose metabolism as well as on energy balance and sleep regulation. The role of N-acylethanolamides like oleoylethanolamide (OEA) and other endocannabinoids such as anandamide (AEA) and 2-arachidonyl-glycerol (2-AG) has not yet been investigated in patients with sleep apnea.

 

CONCLUSIONS: These results indicate that among the three analyzed fatty acid derivatives, OEA plays a specific role in patients with sleep apnea. Together with animal data, the 2-fold elevation of OEA serum concentrations could be interpreted as a neuroprotective mechanism against chronic oxidative stressors and a mechanism to promote wakefulness in patients with nocturnal sleep deprivation and daytime hypersomnolence.”

“OBJECTIVE: To observe the differences of endogenous cannabinoid system (ECS) synthetic and catabolic enzyme levels between the obstructive sleep apnea syndrome (OSA) patients and the control subjects.

 

CONCLUSION: OSA altered the expression of the ECS synthetic and catabolic enzymes, leading to an increase in endogenous cannabinoid substances.”
