Sleeping with a clunky respiration machine is an issue for a lot of with sleep apnea, however a extra snug different is on the horizon.
In a current scientific drug trial that ended in 2023, individuals who took the very best each day dose of an epilepsy drug had almost 50 p.c fewer respiration interruptions whereas sleeping.
“We have been working on this treatment strategy for a long time, and the results show that sleep apnea can indeed be influenced pharmacologically,” says Jan Hedner, who specializes in pulmonary drugs on the University of Gothenburg in Sweden.
“It feels like a breakthrough, and we now look forward to larger and longer studies to determine whether the effect is sustained over time and whether the treatment is safe for broader patient groups.”
Sleep apnea can happen when the higher airways all of a sudden collapse in periods of relaxation, main to obstructed respiration patterns that deprive the physique of oxygen and frequently disrupt sleep.
CPAP (steady constructive airway strain) machines are designed to maintain the higher airway open all through the night time. For a few years, this has been the usual and best method to enhance sleep in sufferers.
At the very finish of 2024, nonetheless, the US Food and Drug Administration (FDA) approved a drug known as tirzepatide (model names Mounjaro or Zepbound) for adults with weight problems and moderate-to-severe sleep apnea.
This was the primary drugs to be authorized for the airway situation, however its sleep-related advantages primarily appear to stem from weight reduction in the neck, creating a bigger airway that’s much less susceptible to obstruction.
This remedy doesn’t deal with different underlying problems with obstructive sleep apnea, akin to muscle energy in the airways or the physique’s respiratory management.
Hedner and colleagues argue “there is a clear, unmet need for an effective and well-tolerated treatment” that’s extra direct.
The anticonvulsant drug they’re testing is known as sultiame. It was first synthesized in the Fifties, and whereas it’s now offered in a number of European nations, in addition to Israel, Japan, and Australia, to deal with partial seizures, it has by no means been registered in the US.
In a preliminary examine in 2024, researchers in Europe found that sultiame may enhance higher airway muscle tone and stabilize respiratory management.
Building on these outcomes, researchers on the University of Gothenburg have now performed a big, stage II clinical trial to discover an acceptable dosage for sleep apnea.
They break up a cohort of 240 individuals into 4 teams: one took a placebo each day, and the opposite three teams took both 100 mg, 200 mg, or 300 mg of sultiame each day.
Participants included in the trial hailed from medical establishments in 5 European international locations (Belgium, Czechia, France, Germany, and Spain), they usually had all been recognized with average to extreme obstructive sleep apnea.
Those who took any dose of sultiame an hour earlier than mattress confirmed fewer respiration disturbances, higher in a single day oxygenation, and diminished extreme daytime sleepiness, in contrast to the placebo group.
Those taking the 2 highest doses of sulthiame, nonetheless, reaped essentially the most advantages. Doses of 200 mg or 300 mg diminished sleep apnea severity by roughly 30 to 50 p.c, the trial researchers report, far outperforming the placebo.
There have been no clinically related security issues, however as a result of unwanted side effects enhance with the dosage, 200 mg appears to be the candy spot.
“These findings introduce a new individualized pharmacotherapy in patients with sleep disordered breathing,” conclude Hedner and colleagues.
Sleep apnea is estimated to have an effect on hundreds of thousands of individuals worldwide and is linked to a number of unfavorable well being results, together with cognitive issues, cardiovascular disease, and insulin problems. Some research counsel that the danger of creating the situation is ready to enhance by nearly 50 percent in the approaching years.
Effective remedies are few and much between. Taping the mouth shut could worsen sleep apnea, researchers say, and even some mouth guards that push the tongue ahead have downsides to think about, akin to altering an individual’s chew.

Other researchers have tried utilizing electrical pulses on the tongue to maintain the higher airways open, and a few current research have even discovered that blowing a conch shell may help, too.
A drug that may deal with the basis causes of sleep apnea can be a welcome addition to the combination, with the potential to make remedies cheaper, extra accessible, and extra snug the world over.
The examine was printed in The Lancet.
