"Using a randomised, blind trial, 10 people with sleep apnoea were given either the potassium blocker nasal spray, a placebo nasal spray or the potassium nasal spray in combination with restricted 'nasal only' breathing. ...
When used in a nasal spray, the blockers have the potential to increase the activity of the muscles that keep the upper airway open and reduce the likelihood of the throat collapsing during sleep," lead author Dr Amal Osman, said.
Seven out of the 10 people responded to the potassium channel blocker nasal spray, with is causing a reduction in the frequency of upper airway collapsing episodes during sleep.
They also had lower blood pressure the next morning.
He said the insight offers a pathway to developing new drugs for the condition.
CPAP is the proven Gold Standard for treating sleep apnea.
