Each of 40 randomized patients was treated in sequence with two of the five agents (balanced incomplete block design). Treatment periods lasted 6 wk and were separated by a 3-wk washout period. Changes in BP from baseline with the study substances were compared through analysis of variance. Office diastolic BP, our primary outcome variable, was most effectively lowered by atenolol, with all four post hoc differences between atenolol and the remaining substances being statistically significant. Reductions in office systolic and daytime ambulatory BP were not significantly different among the five compounds. However, atenolol reduced mean nighttime ambulatory diastolic and systolic BP more effectively than did amlodipine, enalapril, or losartan (but not hydrochlorothiazide). Severity of sleep-disordered breathing and well-being during the day were not significantly influenced by any of the study compounds. Our findings are in accordance with the hypothesis that an overactivity of the sympathetic nervous system is an important mechanism behind the development or maintenance of hypertension in patients with OSA.<\/jats:p>","DOI":"10.1164\/ajrccm.161.5.9909024","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T14:16:55Z","timestamp":1365085015000},"page":"1423-1428","source":"Crossref","is-referenced-by-count":131,"title":["Comparison of Atenolol, Amlodipine, Enalapril, Hydrochlorothiazide, and Losartan for Antihypertensive Treatment in Patients with Obstructive Sleep Apnea"],"prefix":"10.1093","volume":"161","author":[{"given":"HOLGER","family":"KRAICZI","sequence":"first","affiliation":[{"name":"Departments of Pulmonary Medicine and Clinical Pharmacology, Sahlgrenska University Hospital, Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JAN","family":"HEDNER","sequence":"additional","affiliation":[{"name":"Departments of Pulmonary Medicine and Clinical Pharmacology, Sahlgrenska University Hospital, Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y\u00dcKSEL","family":"PEKER","sequence":"additional","affiliation":[{"name":"Departments of Pulmonary Medicine and Clinical Pharmacology, Sahlgrenska University Hospital, Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LUDGER","family":"GROTE","sequence":"additional","affiliation":[{"name":"Departments of Pulmonary Medicine and Clinical Pharmacology, Sahlgrenska University Hospital, Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2000,5,1]]},"reference":[{"key":"2026032708400965600_B1","doi-asserted-by":"crossref","first-page":"190","DOI":"10.7326\/0003-4819-103-2-190","article-title":"Undiagnosed sleep apnea in patients with essential hypertension.","volume":"103","author":"Fletcher","year":"1985","journal-title":"Ann.
