In 6 patients, in whom a pheochromocytoma was surgically approved later on, norepinephrine was not suppressed by clonidine. 17 patients in whom a secondary form of hypertension could be excluded by other diagnostic measures showed a marked decrease of plasma norepinephrine. Apart from drowsiness, no adverse side effects were observed. In our hands, the clonidine test proved as a safe and specific test in the diagnosis of pheochromocytoma.<\/jats:p>","DOI":"10.1159\/000173965","type":"journal-article","created":{"date-parts":[[2008,11,12]],"date-time":"2008-11-12T08:17:04Z","timestamp":1226477824000},"page":"157-159","source":"Crossref","is-referenced-by-count":4,"title":["Preliminary Results with the Clonidine Suppression Test in the Diagnosis of Pheochromocytoma"],"prefix":"10.1159","author":[{"given":"K.","family":"Brandstetter","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U.","family":"Krause","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Beyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,11,11]]},"container-title":["Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000173965","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T16:28:38Z","timestamp":1777480118000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000173965"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,11,11]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000173965","archive":["Portico"],"relation":{},"ISSN":["0008-6312","1421-9751"],"issn-type":[{"value":"0008-6312","type":"print"},{"value":"1421-9751","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,11,11]]}}}
