常見問題列表
特立帕肽皮下注射后吸收及消除速度都很快，皮下注射本品20 μg，達峰時間(tmax)為30 min，半衰期(t1/2 )為60 min，靜脈注射血清半衰期為5 min，絕對生物利用度95%。90%藥物經(jīng)腎臟清除。
特立帕肽注射后常見不良反應包括頭暈、背痛、惡心和下肢痙攣等，多為一過性；少見的不良反應包括心律失常、耳聾等。目前認為不良反應發(fā)生與患者年齡和給藥劑量之間無明顯關系。
2011年復泰奧（特立帕肽）在全球銷售額達到9.51億美元。在中國市場，2011 年由禮來（法國）公司開始進口。

Trabecular bone calcium and dry weight of the distal femur increased significantly in Teriparatide-treated animals. The increase in trabecular calcium compared with vehicle control occurred as early as 1 week after initiation of treatment with a 35% and 45% increase, respectively, for 10 μg/kg and 40 μg/kg Teriparatide. Similar results were observed for trabecular dry weight. After 4 weeks of treatment with 10 mg/kg or 40 mg/kg Teriparatide, trabecular calcium increased significantly by 70% and 123%, respectively, compared with the vehicle and by 73%.
The 4-week Teriparatide administration increase the pore ratio, number, and density as well as the cortical area, thickness, and bone mineral content (BMC), without significant influencing the volumetric bone mineral density (BMD). The 4-week Teriparatide administration + 8-week vehicle administration decrease the pore ratio, number, and density as well as the cortical area and thickness, compared with the 4-week Teriparatide administration, but the pore ratio, cortical area, and thickness are still higher compared with the 12-week vehicle administration. The 4-week Teriparatide administration + 8-week higherdose IBN administration increase the cortical area, thickness, BMC, and volumetric
BMD and decrease the pore ratio, but not the pore number or density, compared with the 4-week Teriparatide administration + 8-week vehicle administration.
