However, effects of therapeutic doses on locomotor activity and the cardiovascular system have not been studied in conscious animals. The effects of buprenorphine were therefore evaluated in this study using telemetric monitoring in conscious animals. Telemetry transmitters were implanted in the peritoneal cavity of Wistar rats with a pressure catheter in the aorta and electrodes for electrocardiogram (ECG) recording subcutaneously. After a single subcutaneous administration of saline, each rat was administered single subcutaneous doses of 0.006, 0.03 or 0.15 mg\/kg body weight (bw) of buprenorphine. During a 10 h period after administration, buprenorphine induced a varying dose-dependent increase in body temperature, heart rate, d P\/d t and systolic\u2013diastolic blood pressure, as well as a corresponding decrease in QT time. At high dose, however, QT time was still decreased 24 h post-administration, but no arrhythmias or visual changes were observed in the ECG complex. Body temperature and heart rate increased at the high dose of buprenorphine, even at 20\u201324 h after administration. Moreover, the high dose of buprenorphine induced a biphasic response in diastolic blood pressure, with an early and pronounced increase that, at 14 h after administration, reversed to a decrease, failing to normalize within 24 h post-dosage. The results indicate that buprenorphine induces long-lasting effects (such as body temperature and cardiovascular effects) in the rat after a single subcutaneous dose at 0.15 mg\/kg bw. <\/jats:p>","DOI":"10.1258\/la.2007.06002e","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T01:20:11Z","timestamp":1208827211000},"page":"149-160","source":"Crossref","is-referenced-by-count":19,"title":["Effects of buprenorphine on body temperature, locomotor activity and cardiovascular function when assessed by telemetric monitoring in rats"],"prefix":"10.1177","volume":"42","author":[{"given":"N-G","family":"Ilb\u00e4ck","sequence":"first","affiliation":[{"name":"Toxicology Division, National Food Administration, Uppsala, Sweden"},{"name":"Section of Infectious Diseases, Department of Medical Sciences, Uppsala University, S-751 85 Uppsala, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Siller","sequence":"additional","affiliation":[{"name":"Active Biotech Research AB, Lund, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T","family":"St\u00e5lhandske","sequence":"additional","affiliation":[{"name":"Active Biotech Research AB, Lund, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2008,4,1]]},"reference":[{"key":"bibr-LA-06-002eC1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1989.tb12019.x"},{"key":"bibr-LA-06-002eC2","first-page":"90","volume":"34","author":"Brackee G","year":"1995","journal-title":"Contemporary Topics in Laboratory Animal Science"},{"key":"bibr-LA-06-002eC3","first-page":"109","volume":"16","author":"Brema F","year":"1996","journal-title":"International Journal of Clinical Pharmacology Research"},{"key":"bibr-LA-06-002eC4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1977.tb07532.x"},{"key":"bibr-LA-06-002eC5","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/49.3.251"},{"key":"bibr-LA-06-002eC6","doi-asserted-by":"publisher","DOI":"10.1016\/0031-9384(88)90209-0"},{"key":"bibr-LA-06-002eC7","doi-asserted-by":"crossref","unstructured":"FELASA Working Group on Health Monitoring of Rodent and Rabbit Colonies (2002) Recommendations for the health monitoring of rodent and rabbit breeding colonies in breeding and experimental units.
