目的评价伊班膦酸钠、伊班膦酸钠联合骨肿瘤局部病灶的放射治疗及单纯放射治疗的临床疗效的优劣。方法回顾性分析本院近5年门诊及住院71例次各类恶性骨肿瘤患者,其中20例为以伊班膦酸钠为主体的综合治疗,26例次是以伊班膦酸钠联合骨肿瘤局部病灶放射治疗的综合治疗,25例次单纯对骨肿瘤病灶采取了姑息放射治疗;按WHO规定评价疗效及不良反应。结果病灶局部疼痛控制情况:3组总有效率依次为70.0%,88.5%,68.0%;骨肿瘤溶骨性病灶骨密度增加好转率依次为65.0%,80.8%,48.0%。结论尽管3组之间的疗效经统计学处理未见显著差异,但伊班膦酸钠联合放射治疗是在骨肿瘤病人疼痛反应的缓解率和增加溶骨性病灶骨密度等方面都优于其它两组,因此,本组资料认为伊班膦酸钠联合放射治是一种值得推广的骨肿瘤姑息治疗手段。 相似文献

BACKGROUND: Osteoporosis is a frequent complication in Crohn's disease. Although the efficacy of both sodium fluoride and aminobisphosphonates in postmenopausal osteoporosis has been investigated in long-term therapy studies, no long-term results are available regarding the effect of these agents in the management of osteoporosis in patients with Crohn's disease. METHODS: Eighty-four patients with Crohn's disease and pathological bone mineral density findings were randomized to receive either vitamin D3 (1000 IU) and calcium citrate (800 mg) daily (group A) or sodium fluoride (25 mg b.d., group B) or intravenous ibandronate (1 mg every 3 months, group C) in addition to daily calcium/vitamin D substitution. On admission to the study and after 12 and 27 months, patients underwent dual-energy X-ray absorptiometry and radiological examination of the spine. RESULTS: Sixty-eight patients completed the 1-year observation period and were available for the intention-to-treat analysis. No new vertebral fractures were diagnosed. In group A, lumbar bone density increased by 2.6% (P = 0.066, N.S.), in group B by 5.7% (P = 0.003) and in group C by 5.4% (P = 0.003). Therapy with sodium fluoride was associated with an increase in osteocalcin (N.S.), whereas administration of ibandronate was associated with a decrease in the resorption parameter, carboxy-terminal cross-linked type-I collagen telopeptide (P < 0.05). Both sodium fluoride and ibandronate resulted in significant decreases in the serum concentration of osteoprotegerin after 9 months (P < 0.001). CONCLUSIONS: The findings of the present study show that both sodium fluoride and ibandronate are effective in combination with calcium and vitamin D substitution in the management of osteopenia and osteoporosis in patients with Crohn's disease. Both agents are safe and well tolerated, and induce continuous increases in lumbar bone density. 相似文献

A simple and sensitive ion chromatography method has been developed for the simultaneous assay of ibandronate sodium drug substance and the determination of its impurities. The separation was achieved on Allsep™ anion column 150 mm × 4.6 mm, 7 μm particle diameter. The mobile phase consisted of 1% (v/v) aqueous formic acid and acetone 98:2% (v/v); flow rate 1.0 ml min−1 at ambient temperature. The analytes were monitored by conductometric detector. The drug substance was subjected to stress conditions of hydrolysis, oxidation, photolytic, thermal and humidity degradation. Considerable degradation was achieved only under oxidative conditions. Mass balance was demonstrated in all stress conditions. The method was validated for specificity, precision, linearity, solution stability and accuracy. The limits of detection (LOD) and limits of quantification (LOQ) for impurities were in the range of 0.36–0.80 μg ml−1 and 1.00–2.40 μg ml−1, respectively. For ibandronate LOD was 38 μg ml−1 and LOQ was 113 μg ml−1. The average recoveries for impurities and ibandronate were in the range of 99.0–103.1% and the method can be successfully applied for the routine analysis of ibandronate sodium drug substance. 相似文献

BACKGROUND: Postmenopausal osteoporosis is a serious, chronic condition, for which nitrogen-containing bisphosphonates are now one of the treatments of choice. OBJECTIVE: To review the profile of ibandronate, a monthly oral (150 mg) or quarterly intravenous injection (3 mg) of bisphosphonate. METHODS: The literature search was limited to publications of ibandronate data. RESULTS/CONCLUSION: Ibandronate is rapidly absorbed and distributed in the bone; it is not metabolised and is excreted in urine. Clinical trial data have demonstrated the efficacy of ibandronate in reducing fracture risk, increasing bone mineral density and reducing bone turnover. These data are supported by recent meta-analyses and a large database study that have demonstrated antifracture efficacy with the ibandronate regimens used in clinical practice. Overall, ibandronate has generally been well tolerated. Therefore, ibandronate is a useful treatment for postmenopausal osteoporosis. 相似文献

OBJECTIVES: BONE (oral iBandronate Osteoporosis vertebral fracture trial in North America and Europe) determined whether less frequent dosing of ibandronate (dose-free interval > 2 months) provided similar antifracture efficacy to daily dosing. As osteoporosis medications must be effective across different populations, an additional objective of BONE was to investigate and report the effect of oral ibandronate in North American and European women, as described here. PATIENTS AND METHODS: BONE was a randomized, double-blind, placebo-controlled, fractureprevention study in 2946 postmenopausal women (age 55 years-80 years; > or = 5 years since menopause) with osteoporosis (low lumbar spine bone mineral density and one to four prevalent vertebral fractures [T4-L4]). Participants received daily calcium (500 mg) and vitamin D (400 IU) plus either placebo, oral daily ibandronate (2.5 mg) or oral intermittent ibandronate (20 mg every other day for 12 doses every 3 months). The efficacy and tolerability of ibandronate were assessed independently in both North American and European populations. RESULTS: Consistent, significant efficacy was observed in the North American (new vertebral fracture risk reduction: 60% and 54% with daily and intermittent ibandronate, respectively) and European patient populations (50% and 48%, respectively). Both ibandronate regimens also significantly reduced the incidence of new, worsening, and acute clinical, vertebral fractures. Daily and intermittent ibandronate significantly increased bone density at the spine in both North American (5.4% and 4.4% vs. baseline with daily and intermittent ibandronate, respectively) and European (7.1% and 6.3% vs. baseline, respectively) populations. Significant increases were also observed for total hip bone density (2.6% and 3.7% vs. baseline for daily, and 2.5% and 3.1% for intermittent; North American and European populations, respectively). Comparable, significant decreases in biochemical markers of bone turnover (reductions in urinary excretion of C-telopeptide levels of 53.5% and 67.1% vs. baseline for daily, and 50.0% and 53.8% for intermittent; North American and European populations, respectively) were also observed in both populations (p < 0.004 for all cited measurements in each ibandronate group vs. placebo). Oral ibandronate was well tolerated in both North American and European patients, with a safety profile similar to placebo. CONCLUSIONS: Oral ibandronate, administered daily or intermittently, effectively reduced vertebral fracture risk in North American and European women with postmenopausal osteoporosis. These results demonstrate the efficacy of ibandronate administered with extended dose-free intervals, regardless of patients' geographical origin. Research investigating other less frequent ibandronate regimens, such as once-monthly oral administration, is underway. 相似文献

In this open-label study, the authors assessed the pharmacokinetics and safety of ibandronate in patients with multiple myeloma and varying renal function. Renal deterioration was graded at baseline depending on creatinine clearance in 4 stages (0: >80; 1: 50-79; 2: 30-49, and 3: <30 mL/min). Patients (n = 40) received intravenous ibandronate 6 mg (30-minute infusion). Ibandronate excretion and serum levels were measured over 24 hours. Serum creatinine, creatinine clearance, and markers of tubular damage were monitored before ibandronate infusion and at 24 and 72 hours following ibandronate infusion. Ibandronate clearance, AUC(0-24), AUC(0-infinity), serum t((1/2)), and C(max) were calculated. There was a significant positive correlation between ibandronate clearance and creatinine clearance (r = 0.858; P < .00001). The AUC for grade 3 renal insufficiency increased by approximately 60% versus grade 0 (P < .01) but was not significantly different between other grades of renal function. The t((1/2)) did not increase significantly, and peak serum levels of ibandronate were similar for the 4 grades of renal function. Serum creatinine, creatinine clearance, and markers of tubular damage did not change significantly within 72 hours of ibandronate infusion. Despite renal function already being compromised in this patient group, there was no evidence of acute nephrotoxicity with ibandronate. 相似文献
