RT Journal Article SR Electronic T1 Recombinant human PTH 1-34 (Forteo): An anabolic drug for osteoporosis JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 585 OP 601 VO 70 IS 7 A1 Deal, Chad A1 Gideon, James YR 2003 UL http://www.ccjm.org/content/70/7/585.abstract AB Forteo (teriparatide of rDNA origin), a genetically engineered fragment of parathyroid hormone, is the first of a new class of drugs to treat osteoporosis. The drug’s anabolic action increases bone turnover, stimulating osteoblasts to a greater extent than osteoclasts, and reducing both vertebral and nonvertebral fractures. However, a number of issues about its use remain unanswered.
