Abstrakt: Background: Osteoporosis has been recognized as a significant health issue in Thailand. Pharmacological interventions are important way to prevent fracture. However, one of the main challenges in selecting a medication is high cost, particularly for brand-name drugs. Data on generic bisphosphonate use in Thai are still lacking. Therefore, our study aimed to assess the efficacy and safety of generic risedronate in postmenopausal Thai women with osteoporosis.
Methods: This prospective study was conducted at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, from December 2022 to January 2024. Serum C-terminal cross-linking telopeptide of type I collagen (CTX) and procollagen type I N-propeptide (P1NP) were measured at baseline. All participants subsequently received 35 milligrams of oral risedronate once weekly for 52 weeks. Serum CTX and P1NP were remeasured at different time points. BMD was reevaluated at 52 weeks after risedronate treatment initiation.
Results: A total of 80 participants were included. The mean age was 65.2 ± 6.6 years. The mean body mass index (BMI) was 23.45 ± 3.49 kg/m 2 . The median (IQR) serum CTX level at 12 weeks was significantly lower than that at baseline (0.28 (0.16-0.46) ng/mL versus 0.44 (0.26-0.64) ng/mL, respectively; p value < 0.01). The suppression of serum CTX was confirmed at 52 weeks after treatment initiation. Compared with those at baseline, the serum P1NP levels were significantly lower at 24 weeks after treatment initiation (30.33 (19.19-39.58) ng/mL versus 41.90 (30.33-68.67) ng/mL, respectively; p value < 0.01). In terms of the BMD assessment at 52 weeks, significant improvements were observed in both areal BMD (g/cm 2 ) and T scores at all measured sites compared with baseline. The lumbar spine, femoral neck, and total hip BMD increased from baseline by 4.76%, 3.84% and 4.54%, respectively.
Conclusion: Postmenopausal women with osteoporosis who were treated with generic risedronate demonstrated significant suppression of the bone remodelling process at 3, 6, and 12 months after treatment initiation. Additionally, significant improvements in the lumbar spine, femoral neck, and total hip BMD were observed at 12 months of therapy. These findings suggest that generic risedronate could be considered a reasonable and interesting option for treating postmenopausal women with osteoporosis in Thailand.
