The frequency of gastrointestinal adverse https://www.selleckchem.com/products/Flavopiridol.html events with daily IR risedronate and the DR doses in this study is consistent with previous studies of daily, weekly, and monthly dosing with risedronate [11–13].

adverse events, and acute phase reaction adverse events. Clinical fractures are defined as all nonvertebral fractures and symptomatic, radiographically confirmed vertebral fractures that occurred after randomization and were reported as adverse events. Acute phase reactions are defined as influenza-like illness and/or pyrexia starting within 3 days following the first dose of study drug and having a duration of 7 days or less. Clinical vertebral and nonvertebral fractures occurred infrequently. The numeric differences noted were not statistically significant, and the types of fractures were similar among the treatment groups. Musculoskeletal adverse events were reported by similar proportions of subjects across treatment groups (Table 2). No cases of acute phase reaction or osteonecrosis of the jaw were reported. Small decreases in serum calcium and the expected reciprocal increases in serum iPTH 1–84 were seen within the first few weeks of treatment, as expected upon initiation of antiresorptive therapy.
