The changes in bone turnover markers were also similar between both monthly regimens and the daily regimen. Safety profiles for the monthly regimens were similar to that of the daily regimen. These results suggest that minodronate, for which a daily dose has been shown to have antivertebral fragility fracture (VFx) efficacy, can be administered monthly in the same manner as risedronate [7, 13] and ibandronate [14, 15]. In the present study, there was a transient decrease in the serum Ca level and a transient increase in the serum PTH level. The magnitudes and time courses of these changes were LGX818 slightly different among different regimens. As shown in Fig. 3, although statistically nonsignificant, the magnitude of the inhibition of bone resorption markers was numerically different among groups especially at early time points. This may well be reflected to the differences check details in the changes of serum Ca and PTH. However, the responses in terms of BMD and bone turnover markers were not different among the

three groups. Thus, the influence of subtle differences in Ca and PTH on bone was not clear. Similar transient changes in Methocarbamol Ca and PTH were previously reported with oral alendronate [16, 17] and risedronate [18] without known effects on bone. The major limitation of the present study was that it did not have the power to assess antifracture efficacy. However, BMD change has been accepted as a valid surrogate endpoint when evaluating a new dosage schedule for a bisphosphonate for which a fracture benefit has been established [3, 4, 7, 14, 19]. Thus far, no oral bisphosphonate has demonstrated antifracture https://www.selleckchem.com/products/azd6738.html efficacy with a weekly or monthly regimen in randomized controlled trials. The magnitude of BMD change by

monthly minodronate in the present study was similar to that achieved by daily minodronate in the previous studies [1]. The changes in bone turnover markers were also comparable [1, 2]. These data suggest that the monthly and daily regimens of minodronate would be equally beneficial to bone. Another limitation in this study was that only a limited number of men were recruited. Thus, it was impossible to analyze whether or not minodronate would be equally effective to men as well. However, when the data from all three regimens were combined and analyzed using a per protocol set, the LS-BMD change from the baseline to the end of the study was 5.33% (95% CI 3.00–7.66) in men (n = 9), which was comparable to that in women (n = 605) [6.39% (6.09–6.70)]. The change in hip BMD was 1.10% (95% CI −0.34 to 2.53) in men (n = 8), which was smaller than that in women (n = 591) [2.94% (2.74–3.13)].
