Obstructive sleep apnea is a common sleep disorder that affects millions of people around the world. The condition happens when the upper airway becomes blocked again and again during sleep.
These repeated blockages interrupt breathing, often causing loud snoring, choking sounds, and poor-quality sleep throughout the night.
Many people with sleep apnea do not realize they have the condition. They may wake up feeling tired, struggle with daytime sleepiness, headaches, poor concentration, or mood changes. Some people even fall asleep during work, driving, or daily activities because their sleep is constantly interrupted.
Sleep apnea is not just about feeling tired. Over time, the condition can seriously affect health. Studies have shown that untreated sleep apnea raises the risk of high blood pressure, heart disease, stroke, type 2 diabetes, and memory problems.
Because oxygen levels repeatedly drop during the night, the heart and other organs are placed under extra stress.
Right now, the most common treatment for obstructive sleep apnea is continuous positive airway pressure, usually called CPAP. This treatment uses a machine connected to a face mask. The machine gently pushes air into the airway to stop it from collapsing during sleep.
CPAP is considered very effective, and for many patients it can greatly improve sleep and reduce health risks. However, many people find the mask uncomfortable or difficult to use every night.
Some patients dislike the feeling of wearing a mask while sleeping, while others struggle with dry mouth, noise, skin irritation, or discomfort from the airflow. Research shows that many patients stop using their CPAP machines within the first year.
Because of these problems, scientists have been searching for easier and more comfortable treatments for sleep apnea. Now, a new study suggests that a pill called sulthiame may offer another option for some patients.
The study was partly led by researchers from University of Gothenburg and was published in the medical journal The Lancet.
The clinical trial involved 298 adults with moderate to severe obstructive sleep apnea. The study took place across four European countries.
Researchers used a double-blind design, meaning neither the participants nor the scientists knew who was receiving the actual drug and who was receiving a placebo pill with no active medicine. This type of study design helps make the results more reliable.
Participants were divided into several groups. Some received the placebo, while others received sulthiame at different doses. The researchers then carefully monitored the number of breathing interruptions people experienced during sleep.
The results were very encouraging. Patients taking the higher doses of sulthiame experienced up to 47 percent fewer breathing pauses during sleep compared with the placebo group. Their oxygen levels during sleep also improved.
The drug appears to work by helping stabilize the body’s breathing control system. It increases the drive to breathe and makes it less likely that the upper airway will collapse during sleep. This helps keep airflow moving more normally throughout the night.
Another important finding was that most side effects from the drug were mild and temporary. Many patients tolerated the treatment well, which raises hope that the medicine could become a practical option for people who cannot comfortably use CPAP.
Sulthiame itself is not a completely new medicine. It has already been approved in some countries for treating certain forms of epilepsy in children. Because doctors already have experience using the drug, scientists already know a lot about its safety and side effects. This may help speed up future research into its use for sleep apnea.
One of the senior researchers involved in the study was Professor Jan Hedner from the Sahlgrenska Academy at the University of Gothenburg. He and his team have been studying this treatment approach for many years. He described the findings as a possible breakthrough for sleep apnea care.
Other important contributors from the University of Gothenburg included Ludger Grote and Kaj Stenlöf. The researchers now hope to carry out larger and longer studies to better understand the long-term safety and effectiveness of sulthiame for sleep apnea patients.
The findings could mark an important shift in the way sleep apnea is treated. For many years, treatment has mainly depended on machines, masks, or surgery. A medicine that can improve breathing during sleep using a simple pill could make treatment much easier for many patients.
Although more research is still needed before sulthiame becomes widely available for sleep apnea treatment, the results give new hope to people who struggle with CPAP therapy. In the future, some patients may be able to manage their condition with medication instead of relying only on breathing machines.
