Millions of people around the world rely on a bulky breathing machine called a CPAP to get through the night, and many of them quietly give up on it because sleeping with a mask strapped to your face simply becomes too difficult to keep doing. Now, for the first time, scientists may have found a genuine pill that could change everything for sleep apnea patients. A large European clinical trial involving nearly 300 people with moderate to severe sleep apnea tested a drug called sulthiame, which had previously only ever been approved to treat a form of childhood epilepsy. Patients who received higher doses of the medication experienced up to 47 percent fewer breathing interruptions during the night and woke up with measurably better oxygen levels in their blood.
The drug appears to work by steadying the brain signals that control breathing, which makes the upper airway far less likely to collapse during sleep and trigger those startling, oxygen-stealing pauses that sleep apnea is known for. The trial was carefully designed so that neither the patients nor the researchers knew who was getting the real drug versus a placebo, and the side effects that were reported were mostly mild and went away on their own. The stakes here are enormous: up to half of all CPAP users abandon their machine within a year, which means tens of millions of people currently have no effective treatment for a condition that raises the risk of heart disease, stroke, high blood pressure, and type 2 diabetes. Researchers at the University of Gothenburg, who led the study, called the results a genuine breakthrough and said they are now planning larger and longer trials to confirm just how much this little pill could change the lives of people who have struggled with sleep apnea for years.
