Losartan in Hypertensive Men and Women With Sleep Apnea Before and on Continuous Positive Airway Pressure (CPAP) Treatment

Summary

Obstructive sleep apnea (OSA) is a highly prevalent condition in hypertensive patients. The renin-angiotension-aldosterone-system (RAAS) has a central role in blood pressure control. An angiotensin-II-antagonist, Losartan, is an effective antihypertensive drug. However, some patients respond to this drug worse than the others, and it is a clinical praxis to either increase the dosage and/or add another drug. There is limited data regarding the impact of antihypertensive drugs in OSA patients, i.e., whether or not OSA may constitute the subgroup of therapy-resistent hypertensive patients. In the literature, there is no data, either, whether or not CPAP treatment may have an additive blood pressure lowering impact in this certain subgroup.
