Tibolone and Its Effects on Bone and Cartilage
Author Information
Author(s): Karsdal MA, Byrjalsen I, Leeming DJ, Christiansen C
Primary Institution: Nordic Bioscience A/S
Hypothesis
Does Tibolone have dual actions on both bone and cartilage turnover similar to some SERMs and HRT?
Conclusion
Tibolone significantly decreases bone resorption without affecting cartilage degradation.
Supporting Evidence
- Tibolone suppressed bone resorption by approximately 60%.
- No effect was observed on cartilage degradation.
- The study involved a total of 91 participants.
Takeaway
Tibolone helps bones stay strong but doesn't help cartilage, which is different from some other treatments.
Methodology
Secondary analysis of a 2-year double-blind, randomized, placebo-controlled study with urine samples collected at multiple time points.
Potential Biases
Potential bias due to the study being conducted by employees of Nordic Bioscience.
Limitations
The study relied on biochemical markers for cartilage degradation, which may not fully represent cartilage health across all joints.
Participant Demographics
Healthy postmenopausal women aged 52–75 years.
