What is sleep apnea?
Sleep apnea is a sleep disorder in which frequent on and off events of breathing take place repeatedly. If you snore loudly and feel tired even after sleeping for more than 8hrs, you might have sleep apnea.
The major types of sleep apnea are:
• Obstructive sleep apnea:- the more common form that occurs when throat muscles relax
• Central sleep apnea:- in which your brain doesn’t send proper signals to the muscles that control breathing into
• Complex sleep apnea:- Treatment-emergent central sleep apnea is the common term referred, which occurs when someone has both obstructive sleep apnea and central sleep apnea at the same time.
A team of researchers at the Institute for Sleep Health at Flinders UniversityAdelaide, Australia, have successfully cut down the severity of sleep apnea in people by 30 %. If untreated, it likely leads to dementia and depression, these patients are more likely to cause car crashes when compared to the population.

The potential remedy for sleep apnea
A team of researchers R. Lim, L. Messineo, R. Grunstein, J. Carberry, D.J. Eckert in Australia have bought us one step closer by using already existing anticholinergic and antidepressants to check their efficacy in people with sleep apnea. The existing data suggested the use of two classes of drugs: reboxetine and butyl bromide that kept muscles active during sleep in people without sleep apnea which in turn increased or enhanced their breathing ability. Using these two drugs, researchers used a range of measuring instruments to quantify whether reboxetine and butyl bromide could target the major cause of sleep apnea. It includes balancing the electrical activity of muscles around the air canal, prevents the throat from collapsing why patients are sleeping, improving the breathing cycle during sleep.
Results showed these drugs enhanced muscle activity and reduced the severity of sleep apnea up to 30%.
There was a sign of improvement in every patient that went through this study. People’s oxygen intake improved, the number of breathing stoppages was a 3rd or less. Researchers are thrilled as treatment options for people with sleep apnea are limited and may be a sore trip for several patients.
These findings will allow researchers to redefine these types of drugs as they have a benefit to what has been discovered. To date, the most major therapy for sleep apnea includes wearing a mask while the patient is asleep or continuous positive airway therapy. However major population affected by sleep apnea find the existing treatments uncomfortable and 50% of the patients find it difficult to tolerate. Second-line therapies include mouthguards fitted by dentists, which are unpredictable and expensive.
Thus reboxetine and butyl bromide can be a breakthrough in treating sleep apnea. Both the drugs are being used in combination. Researchers are working on trying one drug at a time and different drugs from this category are also understudy for finding their potential and long-term use which would be a great sign of relief for millions of sleep apnea patients.
