About this trial
This study investigates the use of blood tests known as Bone Turnover Markers (BTMs) to quickly monitor the effectiveness of osteoporosis treatment in postmenopausal women. Osteoporosis, which weakens bones and increases fracture risk, is typically monitored using a DEXA scan to measure bone density (BMD), but this method changes slowly. BTMs may show a response to medication within just 3 to 6 months. In this randomized controlled trial, 40 postmenopausal women with osteoporosis will be assigned to receive either antiresorptive drugs (which slow bone loss) or anabolic drugs (which build new bone), along with calcium and vitamin D. The study will compare how these treatments affect BTMs and BMD over six months to determine if BTMs can serve as an early and reliable indicator of treatment success, which could be particularly useful in regions like Pakistan where access to repeated DEXA scans is limited.

Treatments tested in this trial
Alendronate, Ibandronate; Risedronate
DrugOral bisphosphonate tablets. Participants will receive one of the following specific regimens: Alendronate 70mg taken once per week, Ibandronate 150mg taken once per month, or Risedronate 150mg taken once per month. This is combined with daily Calcium and Vitamin D supplementation. The total treatment duration is 6 months.
Teriparatide
DrugA solution for subcutaneous injection. The dosage is 20 micrograms (mcg) injected once daily. This is combined with daily Calcium and Vitamin D supplementation. The total treatment duration is 6 months.

Trial outcomes
Primary outcomes
Change in Bone Turnover Markers (BTMs)
Mean change from baseline in the serum levels of specific bone turnover markers, including the bone formation marker Bone-Specific Alkaline Phosphatase (BsALP) and the bone resorption marker Tartrate-Resistant Acid Phosphatase 5b (TRACP-5b), and the osteocyte marker Sclerostin.
Change in Bone Mineral Density (BMD)
Mean change from baseline in Bone Mineral Density (BMD) T-score as measured by Dual-Energy X-ray Absorptiometry (DEXA) scans at the hip, spine, and femoral neck.
Secondary outcomes
Incidence of New Fractures
The number of participants who experience any new fragility fractures during the study period.
