Forteo ® (teriparatide [rDNA origin] injection)
20-mcg daily dose in a 2.4-mL prefilled delivery deviceThis information is provided in response to your request. Resources may contain information about doses, uses, formulations and populations different from product labeling. See Prescribing Information above, if applicable.
Once-daily administration of teriparatide preferentially stimulates osteoblastic activity over osteoclastic activity, resulting in new bone formation.1
New bone formation is observed on the trabecular and cortical (periosteal and/or endosteal) bone surfaces.1
Structural histomorphometric analyses conducted on iliac crest biopsies from PMW with osteoporosis revealed that teriparatide improved
trabecular bone volume
trabecular bone connectivity
structure model index, and
cortical thickness.2
Dynamic histomorphometric analyses conducted on iliac crest biopsies from PMW with osteoporosis demonstrated that teriparatide stimulates bone formation on all bone envelopes (cancellous, endocortical, intracortical, and periosteal) as early as 3 months and remains sustained for the full 24 months of therapy.3,4
Radionuclide bone scan imaging has demonstrated a direct metabolic effect of teriparatide on the whole skeleton and various subskeletal sites.5
New bone formed during teriparatide treatment has lower, more heterogeneous, mineral content, a property consistent with younger bone age.6
