Abstract
BACKGROUND The goal of this study was to review relevant randomized controlled trials or case-control studies to determine the clinical efficacy of minodronate in the treatment of osteoporosis. METHOD The relevant studies were identified on PubMed, Cochrane, and Embase databases using appropriate keywords. Pertinent sources in the literature were also reviewed, and all articles published through October 2019 were considered for inclusion. For each study, we assessed odds ratios, mean difference, and 95% confidence interval (95% CI) to evaluate and synthesize outcomes. RESULT Thirteen studies comprising 3740 patients were included in this study. Compared with other drugs, minodronate significantly decreased N-telopeptide of type I collagen/creatinine (weighted mean difference [WMD]: -13.669, 95% confidence interval [CI]: -23.108 to -4.229), bone alkaline phosphatase (BAP) (WMD: -1.26, 95% CI: -2.04 to -0.47) and tartrate-resistant acid phosphatase 5b (WMD: -154.11, 95% CI: -277.85 to -30.37). Minodronate combined with other drugs would significantly decrease BAP (WMD: -3.10, 95% CI: -5.20 to -1.00) than minodronate. Minodronate-naïve would significantly decrease BAP (WMD: -3.00, 95% CI: -5.47 to 0.53) and tartrate-resistant acid phosphatase 5b (WMD: -128.20, 95% CI: -198.11 to -58.29) than minodronate-switch. The incidence of vertebral fracture was significantly decreased in the minodronate group than the other drugs (relative risk: 0.520, 95% CI: 0.363-0.744). CONCLUSION Minodronate has better clinical efficacy in the treatment of osteoporosis than other drugs (alendronate, risedronate, raloxifene, or eldecalcitol).

Abstract
PURPOSE Two identical, concurrent, parallel, multicenter, randomized, double-blind, double-dummy trials were conducted to compare the efficacy and safety of zoledronic acid and pamidronate for treating hypercalcemia of malignancy (HCM). PATIENTS AND METHODS Patients with moderate to severe HCM (corrected serum calcium [CSC] > or = 3.00 mmol/L [12.0 mg/dL]) were treated with a single dose of zoledronic acid (4 or 8 mg) via 5-minute infusion or pamidronate (90 mg) via 2-hour infusion. A protocol-specified pooled analysis of the two parallel trials was performed. Clinical end points included rate of complete response by day 10, response duration, and time to relapse. RESULTS Two hundred eighty-seven patients were randomized and evaluated for safety; 275 were evaluated for efficacy. Both doses of zoledronic acid were superior to pamidronate in the treatment of HCM. The complete response rates by day 10 were 88.4% (P = .002), 86.7% (P = .015), and 69.7% for zoledronic acid 4 mg and 8 mg and pamidronate 90 mg, respectively. Normalization of CSC occurred by day 4 in approximately 50% of patients treated with zoledronic acid and in only 33.3% of the pamidronate-treated patients. The median duration of complete response favored zoledronic acid 4 and 8 mg over pamidronate 90 mg with response durations of 32, 43, and 18 days, respectively. CONCLUSION Zoledronic acid is superior to pamidronate; 4 mg is the dose recommended for initial treatment of HCM and 8 mg for relapsed or refractory hypercalcemia.
