Abstract

Official abstract text for this publication.

The present invention relates to a combination of selective blockers of TASK-1 and TASK-3 channels, in particular substituted imidazo[1,2-a]pyrimidine and substituted imidazo[1,2-a]pyridine derivatives of formula (I) and norepinephrine reuptake inhibitors for the treatment and/or prophylaxis of sleep-related breathing disorders, preferably obstructive and central sleep apneas and snoring.
