Objective: budget impact assessment on the healthcare system use of teriparatide in the treatment of severe osteoporosis in comparison with antiresorptive drugs.

Material and methods. Study Design – retrospective literature analysis. Methods of pharmacoeconomic analysis: cost analysis, the “budget impact” analysis, sensitivity analysis. In the study, patients were considered as a target group for prescribing the drug teriparatide or antiresorptive therapy with severe postmenopausal osteoporosis with the presumed development of two compression fractures requiring surgical reconstruction.

Results. The use of teriparatide in patients with two low-traumatic vertebral fractures will require a cost 1.4% less than treatment with zoledronic acid and 33.07% less than the treatment with alendronic acid and 13.6% less in comparison with the use of denosumab. At a weighted average frequency of 3 clinically significant fractures per year, the use of teriparatide will require 15.0%, 42.9% and 24.7% less cost, respectively. For a group of 1000 patients with 2 fractures per year, the savings over 4 years will amount to 13.7 million rubles, 483.0 million rubles, respectively and 154.1 million rubles. With a more severe course, expressed in an increase in the number of fractures to 3 per year, budget savings over 4 years per 1000 patients will amount to 219.0 million rubles, 930.9 million rubles and 406.0 million rubles, respectively. A sensitivity analysis showed that on a 4-year horizon, the use of teriparatide remains economically feasible with a decrease in the frequency of fractures to 1.95 per year compared to zoledronic acid, to 1.4 per year compared to denosumab and to 0.95 per year compared alendronic acid.

Conclusion. Teriparatide is more cost effective than antiresorptive drugs for severe osteoporosis, when an average of 2 clinically significant vertebral fractures per year can be expected in untreated patients requiring surgical reconstruction. In this way, the appointment of teriparatide as the first line of therapy for osteoporosis in patients at high risk of fractures, having more than one clinically significant fracture of the vertebral body in a history is justified from a pharmacoeconomic point of view.
