Abstract
Calcitonin has been reported to reduce acute and chronic back pain in osteoporotic patients. The additive effect of calcitonin with a bisphosphonate on chronic back pain remains unclear. The purpose of this study was to evaluate the effect of combining elcatonin (eel calcitonin) with risedronate for patients with chronic back pain. Forty-five postmenopausal women diagnosed as having osteoporosis with chronic back pain persisting for more than 3 months, after excluding women with fresh vertebral fractures within the last 6 months, were randomly allocated to a risedronate group (risedronate alone, n = 22) and a combined group (risedronate and elcatonin, n = 23). The study period was 6 months. Pain was evaluated with a visual analogue scale (VAS) and the Roland-Morris questionnaire (RDQ). Back extensor strength, bone mineral density, and quality of life on the SF-36 and the Japanese osteoporosis quality of life score were also evaluated. Significant improvements were found in the combined group for VAS at final follow-up compared with baseline and 3 months, mental health status on the SF-36, and JOQOL domains for back pain and general health. The JOQOL domain for back pain improved significantly, but no change was found in the VAS or other domains in the risedronate group. Bone mineral density increased significantly in the two groups, but no significant difference was found between the groups. Back extensor strength did not change in both groups. In conclusion, the use of elcatonin in addition to risedronate for more than 3 months reduced chronic back pain. The additional therapy of risedronate with elcatonin may be a useful and practical choice for the treatment of osteoporosis with chronic back pain persisting more than 3 months.

Abstract
Background The polypeptide hormone calcitonin is clinically well known for its ability to relieve neuropathic pain such as spinal canal stenosis, diabetic neuropathy and complex regional pain syndrome. Mechanisms for its analgesic effect, however, remain unclear. Here we investigated the mechanism of anti-hyperalgesic action of calcitonin in a neuropathic pain model in rats. Results Subcutaneous injection of elcatonin, a synthetic derivative of eel calcitonin, relieved hyperalgesia induced by chronic constriction injury (CCI). Real-time reverse transcriptase-polymerase chain reaction analysis revealed that the CCI provoked the upregulation of tetrodotoxin (TTX)-sensitive Nav.1.3 mRNA and downregulation of TTX-resistant Nav1.8 and Nav1.9 mRNA on the ipsilateral dorsal root ganglion (DRG), which would consequently increase the excitability of peripheral nerves. These changes were reversed by elcatonin. In addition, the gene expression of the calcitonin receptor and binding site of 125I-calcitonin was increased at the constricted peripheral nerve tissue but not at the DRG. The anti-hyperalgesic effect and normalization of sodium channel mRNA by elcatonin was parallel to the change of the calcitonin receptor expression. Elcatonin, however, did not affect the sensitivity of nociception or gene expression of sodium channel, while it suppressed calcitonin receptor mRNA under normal conditions. Conclusions These results suggest that the anti-hyperalgesic action of calcitonin on CCI rats could be attributable to the normalization of the sodium channel expression, which might be exerted by an unknown signal produced at the peripheral nerve tissue but not by DRG neurons through the activation of the calcitonin receptor. Calcitonin signals were silent in the normal condition and nerve injury may be one of triggers for conversion of a silent to an active signal.

Abstract
Vertebral collapse is a common fracture associated with osteoporosis. Subsequent pain may be severe and often requires medications and bed rest. Several studies have suggested the use of calcitonin for the treatment of fracture pain. We sought to determine the analgesic efficacy of calcitonin for acute and chronic pain of osteoporotic vertebral compression fractures (OVCF). We searched for randomized, placebo, and controlled trials that evaluated the analgesic efficacy of calcitonin for pain attributable to OVCFs. We performed meta-analyses to calculate standardized mean differences (SMDs) using a fixed or random effects model. The combined results from 13 trials (n = 589) determined that calcitonin significantly reduced the severity of acute pain in recent OVCFs. Pain at rest was reduced by week 1 [mean difference (MD) = -3.39, 95% confidence interval (CI) = -4.02 to -2.76), with continued improvement through 4 weeks. At week 4, the difference in pain scores with mobility was even greater (SMD = -5.99, 95% CI = -6.78 to -5.19). For patients with chronic pain, there was no statistical difference between groups while at rest; there was a small, statistically significant difference between groups while mobile at 6 months (SMD = 0.49, 95% CI = -0.85 to -0.13, p = 0.008). Side effects were mild, with enteric disturbances and flushing reported most frequently. Although calcitonin has proven efficacy in the management of acute back pain associated with a recent OVCF, there is no convincing evidence to support the use of calcitonin for chronic pain associated with older fractures of the same origin.

Abstract
Vertebral collapse is one of the most common fractures associated with osteoporosis. The subsequent back pain is severe and often requires medications, bed rest and hospitalization to control pain and improve mobilization. The purpose of this systematic review was to assess the effects of calcitonin versus placebo for the treatment of acute pain in patients sustaining stable, recent, osteoporotic vertebral compression fractures. MEDLINE (1966-2003), EMBASE (1980-2003), Cochrane Controlled Trial Registry (2003, volume 3), other databases, and conference proceedings were searched for relevant research. Primary study authors and the pharmaceutical manufacturer were contacted, and bibliographies of relevant papers were hand-searched. Randomized, double-blind, placebo-controlled trials comparing calcitonin versus placebo for the acute pain of recent osteoporotic vertebral compression fractures were included. Two reviewers extracted data, performed numeric calculations and extrapolated graphical data independently. The combined results from five randomized controlled trials, involving 246 patients, determined that calcitonin significantly reduced the severity of pain using a visual analogue scale following diagnosis. Pain at rest was reduced as early as 1 week into treatment (weighted mean difference [WMD] =3.08; 95% confidence interval [CI]: 2.64, 3.52) and this effect continued weekly to 4 weeks (WMD =4.03; 95% CI: 3.70, 4.35). A similar pattern was seen for pain scores associated with sitting, standing, and walking. Side effects were gastrointestinal, minor and often self-limited. Calcitonin appears to be effective in the management of acute pain associated with acute osteoporotic vertebral compression fractures by shortening time to mobilization.

Abstract
The aim of this study was to investigate the effect of nasal calcitonin on chronic back pain and disability attributed to osteoporosis. The study design involved three groups of osteoporotic postmenopausal women suffering from chronic back pain. Group I consisted of 40 women with vertebral fractures, group II of 30 women with degenerative disorders and group III of 40 patients with non specific chronic back pain and without abnormality on plain X-rays. Pain intensity was measured using a numerical rating scale (NRS) and disability due to back pain was measured using the Oswestry disability questionnaire. The patients were randomly assigned to receive, for three months, either 200 IU intranasal salmon calcitonin and 1,000 mg of oral calcium daily (groups IA, IIA, IIIA) or 1,000 mg of oral calcium daily (groups IB, IIB, IIIB). Repeated measures ANOVA showed that there were no significant time, group or interaction effects for pain intensity and disability in any of the groups studied. Mean Oswestry and NRS scores were reduced during the follow-up period in the groups IA, IIIA, but the differences between the two time points were not statistically significant. Intranasal calcitonin has no effect on chronic back pain intensity and functional capacity of osteoporotic women regardless of the presence of fractures, degenerative disorders or chronic back pain of non-specific etiology.

Abstract
In this revision, the results of different controlled clinical trials and metaanalyses on the efficacy in the increase of bone mineral density (BMD) and reduction of risk of fracture on postmenopausal osteoporosis treatments are summarized. Most of the drugs studied produce significant BMD increases but with significant differences regarding fracture risk reduction, especially regarding extravertebral fractures. Bisphosphonates and selective estrogen receptor modulators would constitute the first line of treatment of postmenopausal osteoporosis with previous fractures. Head to head studies would be necessary to know its true efficacy since some results are based on post hoc analysis. Possible side effects, risks, treatment comfort and price in addition to the demonstrated efficacy in fracture prevention must be considered in the selection of treatment.

Abstract
We aimed to compare and evaluate the efficacies of a continuous regimen of intranasal salmon calcitonin (SCT) and two cyclic regimens (different cyclic regimens from previous studies) based on alternating 15 days or on 10 days consecutively per month for 1 year in the treatment of postmenopausal osteoporosis. We performed an open-label, prospective, randomized clinical trial. A total of 120 postmenopausal osteoporotic participants between 50 and 65 years old were randomly assigned to one of three treatment groups. Patients in group 1 (n = 40) received continuously SCT nasal spray at a dose of 200 IU/day, plus continuously 500 mg/day elementary calcium and 0.25 microg/day 1-alpha hydroxyvitamin D3, for 1 year. Patients in group 2 (n = 40) received cyclically SCT nasal spray at a dose of 200 IU/day on alternating 15 days per month, plus continuously 500 mg/day elementary calcium and 0.25 microg/day 1-alpha hydroxyvitamin D3, for 1 year. Patients in group 3 (n = 40) received cyclically SCT nasal spray on 10 days consecutively per month (20 days/month rest), plus continuously 500 mg/day elementary calcium and 0.25 microg/day 1-alpha hydroxyvitamin D3, for 1 year. Data was evaluated by repeated analysis of variance (ANOVA). In addition, statistical differences between groups were assessed by the two-tailed Student's t test. After 1 year of the study, seven patients from group 1, eight patients from group 2 and five patients from group 3 withdrew from the study. No patient discontinued the study because of adverse drug effects. There was a statistically-significant improvement in pain intensity VAS scores at the end of the year to baseline scores in all three groups (p < 0.001). There was no significant difference in pain intensity VAS scores between groups at the end of the year (p > 0.05). Lumbar and femur neck BMD scores improved significantly at the end of treatment in all three groups (p < 0.05). There was no statistically-significant difference in BMD scores between groups at final (p > 0.05). Urinary DPD/Cre levels decreased significantly in all three groups by the end of the year (p < 0.05). There was no statistically-significant difference in urinary DPD/Cre final levels between groups (p > 0.05). According to the results of the present study, consecutive 10 days therapy with SCT, which is the first in the literature to our knowledge, is as effective as the other two regimens in the treatment of osteoporosis. Both cyclic regimens in our study (alternating 15 days and 10 consecutive days each month for 1 year) do appear to offer some advantages, especially economically and clinically, as compared to continuous treatment.

Abstract
OBJECTIVE To evaluate the analgesic efficacy of calcitonin for treating the pain of vertebral fractures associated with osteoporosis. DATA SOURCES Searches of MEDLINE (1966-July 2002), Cochrane Library, International Pharmaceutical Abstracts (1977-July 2002), and an extensive manual review of journals were performed using the key search terms calcitonin, analgesic, osteoporosis, vertebral fracture, and pain. STUDY SELECTION AND DATA EXTRACTION All articles identified from the data sources were evaluated and all information deemed relevant was included for this review. DATA SYNTHESIS Fractures, especially vertebral fractures, are a common complication of osteoporosis, leading to significant pain. Calcitonin has been studied for its analgesic properties. Fourteen double-blind, placebo-controlled trials that evaluated the analgesic efficacy of calcitonin for osteoporosis-related vertebral fracture pain were identified and reviewed. Thirteen of these studies demonstrated statistically significant improvement in pain or function in calcitonin-treated patients. CONCLUSIONS Calcitonin has proven efficacy in acute pain associated with osteoporosis-related vertebral fractures. Analgesic effects are seen with intranasal, parenteral, and rectal administration. Future studies comparing calcitonin with other commonly used analgesics are needed to more clearly define its place in therapy.

Abstract
Bone pain is the most common symptom in osteoporotic patients. To date, there is mounting evidence that calcitonin significantly reduces bone pain in osteoporosis, and that the analgesic effect can be evident as soon as the second week of treatment. The limitations to the use of calcitonin, which are parenteral administration and side effects, can now be overcome by the availability of the nasal spray preparation. At present, controlled studies have demonstrated the analgesic activity of calcitonin given by nasal spray in patients with vertebral crush fractures and bone pain. The mechanism for the analgesic effect of calcitonin is yet to be clarified. In humans, similarities between calcitonin and morphine-induced analgesia, and reports of calcitonin-induced elevation of plasma beta-endorphin levels, suggest the possible involvement of the endogenous opiate system in mediating the analgesic action of calcitonin. However, the demonstration of calcitonin binding sites in areas of the brain involved in pain perception and a series of animal studies have raised the possibility that calcitonin may directly modulate nociception in the central nervous system. In support of this hypothesis are some observations of an analgesic effect obtained by direct epidural or subaracnoidal injection of calcitonin in humans.

Abstract
Calcitonin reduces the risk of vertebral fracture in postmenopausal women with osteoporosis. Calcitonin produces small increments in the bone mass of the spine and modestly reduces bone turnover in women with osteoporosis. No significant effect on nonvertebral fractures has been observed. Calcitonin may have analgesic benefit.

Abstract
Osteoporosis is a common problem among postmenopausal women and is associated with significant morbidity, mortality and costs primarily resulting from osteoporotic fractures. Salcatonin (salmon calcitonin) inhibits osteoclastic bone resorption and is approximately 40 to 50 times more potent than human calcitonin. In most randomised trials in which intranasal salcatonin (usually 50 to 200 IU/day plus oral calcium supplements) was administered for 1 to 5 years to postmenopausal women for prevention of osteoporosis, bone mineral density or content of the lumbar spine increased by approximately 1 to 3% from baseline. In contrast, postmenopausal women receiving only oral calcium supplements typically had reductions in bone mineral density or content of about 3 to 6%. The difference between treatment groups was statistically significant in essentially all studies. Although changes in bone mineral density or content were broadly similar in studies of postmenopausal women with established osteoporosis to those in postmenopausal women receiving therapy for prevention of the disease, studies in women with established osteoporosis did not usually demonstrate statistically significant differences between treatment groups. Also in postmenopausal women with established osteoporosis, intranasal salcatonin reduced pain and/or analgesic consumption in some trials and, in a limited number of studies of relatively short duration (i.e. < or = 2 years), the incidence of osteoporotic fractures. A large multicentre 5-year study with adequate statistical power to confirm the effect of intranasal salcatonin on reducing osteoporotic fracture rates in postmenopausal women is currently under way. The intranasal formulation of salcatonin offers a more convenient and better tolerated alternative to the parenteral formulation of the drug which is administered by regular subcutaneous or intramuscular injections. Adverse events associated with the intranasal formulation are generally mild and transient, usually involving local reactions such as nasal discomfort, rhinorrhoea or rhinitis. Thus, for postmenopausal women unable or unwilling to tolerate long term hormone replacement therapy, intranasal salcatonin is an attractive alternative for the management of osteoporosis.
