Osteoporosis, associated with a high turnover of bone and acute bone loss, occurs in a number of clinical models, such as following prolonged steroid therapy, extremity and spinal immobilisation, and often is associated with fracture. Confinement to bed and subsequent hypodynamism relating to the pain following a vertebral fracture may activate the process of high bone turnover and acute bone loss. In postmenopausal women, the acute bone loss resulting from such clinical pictures may be superimposed on to the natural course of bone loss occurring in many postmenopausal women. Salmon calcitonin, a potent inhibitor of osteoclast activity, has been shown to prevent bone loss in all clinical models of acute bone loss due to increased bone turnover and osteoclastic resorption. In addition, salmon calcitonin has a potent analgesic effect, thereby causing a reduction in bone pain and improvement in functional capacity. For these reasons, calcitonin remains a first-line therapy in bone loss related to a hyper-resorptive state.

Salmon calcitonin (s-CT) has been shown to be a valuable analgesic in phantom limb pain (PLP) in several case reports. To evaluate these findings a double-blind crossover comparison of s-CT treatment versus placebo was initiated. Twenty-one out of 161 patients who had undergone major amputations and developed severe PLP 0-7 days after surgery were included in the study. For each patient a matched pair of infusions was prepared containing either 200 IU of s-CT or placebo. Group I (n = 11) was first given s-CT and group II (n = 10) placebo. When PLP reached a level of more than 3 on a numeric analogue scale (NAS) the first infusion was administered. The second infusion (crossover) or more infusions were given when the pain level again exceeded more than 3 on NAS. Using s-CT infusion, PLP was eased from a median of 7 to 4 on NAS in both groups (P less than 0.001), regardless of whether s-CT or placebo was given first. Placebo, however, did not change pain scores (median 7 on NAS, P greater than 0.1). In the s-CT group, but not in the placebo group, 4 individuals remained pain free without a second infusion. Any further treatment was performed with s-CT. One week after the first PLP treatment 19 patients (90%) had pain relief of more than 50%, 16 (76%) were completely pain free, and 15 (71%) never experienced PLP again. One year later 8 out of the 13 surviving patients (62%) still had more than 75% PLP relief. After 2 years PLP exceeded 3 on NAS in 5 individuals (42%), and the remaining 12 patients presented the same PLP as after 1 year. In conclusion, s-CT is a valuable treatment for PLP in the early postoperative period.

Intersternocostoclavicular ossification is a benign arthro-osteitis of the upper anterior chest of unknown cause. Two patients with acute exacerbation of this disorder were successfully treated with intramuscular injections of an eel calcitonin analogue (40 units three times a week). Besides symptomatic relief of local pain and swelling, serial scintigrams showed quantitative improvement in radiophosphonate uptake. The rapid alleviation of pain implies that the hormone has a central analgesic effect, in addition to its direct influence on bone cells and antiinflammatory action. In one patient the disease was associated with palmoplantar pustulosis, which was cured with oral colchicine, whereas the other patient did not have such skin lesions. Despite a hypothetical link between palmoplantar pustulosis and intersternocostoclavicular ossification, colchicine had no beneficial impact on the bone pain. Salmon calcitonin delivered by nasal spray was tried for the second patient but failed, probably because of insufficient drug delivery. The initial favourable results described here warrant future use of calcitonin injection on a larger number of patients with intersternocostoclavicular ossification.

Salmon calcitonin, a polypeptide hormone secreted by the parafollicular C cells of the thyroid gland, lowers serum calcium levels by decreasing bone resorption and renal tubular calcium reabsorption. An analgesic action, possibly mediated via beta-endorphins, is also evident. In the past, parenteral formulations of salmon calcitonin have been used in the management of metabolic bone disorders, but their routine use has been limited by the inconvenience of this route of administration and by poor tolerability. The development of an intranasal preparation of salmon calcitonin will provide a more convenient means of administering the drug. In clinical trials published to date intranasal salmon calcitonin has been effective and well tolerated in small numbers of recently postmenopausal women at risk of developing osteoporosis, and in patients with established osteoporosis, Paget's disease, or osteoporosis secondary to corticosteroid usage, multiple myeloma or ovariectomy. For periods of up to 2 years the drug reduces bone resorption and improves bone architecture, relieves pain and increases functional status. Further research is needed to confirm longer term efficacy (in particular, effects on fracture rate), optimal dosage schedules and the role of intermittent and combination treatment regimens.

Back pain due to vertebral collapse is the main symptom of postmenopausal osteoporosis. The clinical picture in these crush fractures varies, depending on the type and the location of fracture, but in general, a new vertebral crush fracture gives rise to severe pain that immobilizes the patient and necessitates bedrest. In this double-blind controlled clinical trial, 56 patients who had recently (within the last 3 days) suffered an osteoporotic vertebral fracture were hospitalized for a period of 14 days. Salmon calcitonin (100 IU) or placebo injections were given daily. Pain was rated daily on a 10-point scale by the same observers. Blood and urinary parameters were also evaluated. The results showed a significant (P less than 0.001) difference in pain intensity between the calcitonin group and the placebo group. This beneficial effect was generally apparent from the second day of treatment onward, and over the following 2 weeks, the patients were able to sit and stand, and gradually started to walk again. A significant decrease in urinary hydroxyproline and urinary calcium was also noted in the calcitonin group. It is concluded that calcitonin exerts a beneficial effect on back pain following a vertebral crush fracture.

Salmon calcitonin has been used for the management of acute hypercalcemia for the past several years. Unlike other hypocalcemic agents, it is effective within 2 hours after first dosing. This pharmacologic agent shows peak effect at 24-48 hours and has a duration of action of 4-7 days in most cases. Its effectiveness may diminish thereafter despite continuous administration (the so-called "escape phenomenon"). Salmon calcitonin has been shown to be effective in the management of acute hypercalcemia due to a variety of causes, and, because of its low toxicity profile, it may be administered to patients with congestive heart failure or azotemia. Salmon calcitonin is also an analgesic agent in patients with pain associated with bone metastases and may be used in conjunction with other hypocalcemic agents such as mithramycin, the bisphosphonates, or gallium nitrate to prolong the clinical response to more than 1 week. Salmon calcitonin is therefore effective and safe in the management of acute hypercalcemia.

Salmon calcitonin (sCT) is biologically effective when intranasally (i.n.) administered. CT is the treatment of choice for Paget's disease; however, the chronic nature of the disease makes parenteral administration uncomfortable due to the high incidence of adverse reactions occurring after CT injection. The aim of our study was to investigate the efficacy, safety and tolerability of a sCT i.n. spray in the long-term treatment of Paget's disease. Ten pts (4M,6F; age between 58-74 years) with radiological lesions characteristic of Paget's disease, serum alkaline phosphatase (sALP) levels at least 50% above the normal range and never treated for their disease before, were given 200 IU/day of sCT nasal spray for 6 months. sALP levels were measured at month 3 and 6 of therapy; clinical data were recorded every month. sALP levels significantly dropped after 3 months of treatment (72 +/- 6% of basal level, p less than 0.01). After 6 months of therapy sALP levels were similar to the 3 month levels. Pain and functional impairment self-evaluated by the patients decreased after 6 months of therapy: pain index from 5.5 +/- 2.2 to 2.1 +/- 1.1, p less than 0.01; functional impairment index from 2.2 +/- 0.5 to 0.7 +/- 0.5, p less than 0.01. Side-effects were not observed during the entire period of the study. In conclusion, the 200 IU daily regimen of the i.n. spray of sCT without absorption enhancer was, for our patients, effective, safe, and well tolerated in the long-term therapy of Paget's disease.

Salmon calcitonin 100 MRCU/day or a saline placebo were given in daily injections for at least three months to 49 patients with bone metastases from breast cancer in a randomized double-blind trial. All patients were normocalcemic, and most patients had stable or regressing disease at start of trial. No improvement in general performance or bone pain was detected as measured by a visual analogue scale, the daily duration of pain or consumption of analgetic drugs. Calcitonin had no effect on disease progression as judged by bone scans and radiographs. Calcitonin therapy did not affect serum calcium, alkaline phosphatase, bone gla-protein, or the urinary excretion of calcium and hydroxyproline. Serum phosphate and magnesium decreased significantly during calcitonin treatment (p = 0.01, and 0.00005, respectively). It was concluded that salmon calcitonin in this dosage has no discernible effect on skeletal pain, general performance, bone metabolism or disease progression in patients with breast cancer metastatic to bone. A significant decrease in serum phosphate and magnesium probably indicated an effect of calcitonin on the renal excretion of these ions.

The analgesic effect of salmon calcitonin (Calcitonina-Sandoz) was evaluated in an open study of thirty-four patients with bone metastases of a lung cancer. Two different administration protocols were used: eighteen subjects received sCT 400 IU/day for three consecutive days, while the remaining sixteen were given sCT 200 IU/day for six consecutive days. In both protocols salmon calcitonin was diluted in saline and infused intravenously in one hour. Bone, visceral and neuritic pain were evaluated by means of Huskisson's visual analog scale and Keele's pain scale. The analgesic efficacy of salmon calcitonin was also evaluated on the basis of daily consumption of analgesic drugs. Salmon calcitonin proved of extreme efficacy in the treatment of intractable pain from advanced malignancy. A higher and earlier analgesic activity was observed with sCT at the 400 IU daily dosage.

Although the pain-relieving activity of salmon calcitonin has been mainly demonstrated for painful bone metastases it has been postulated that the drug possesses a central analgesic activity which is independent of the opiate receptor system. Thus, 16 patients with neuropathic cancer pain due to radicular compression by extraskeletal metastases, and without the possibility of any specific anticancer treatment, entered the study. Of the 16, 11 were pretreated with opiate-type analgesics. Salmon calcitonin was applied once daily at a dose of 200 IU in 500 ml 0.9% NaCl infused over 1 h. The total duration of the treatment was 20 days. The pain-relieving effect was classified as very good, good, moderate and bad; in 10 patients it was described as bad, in 2 as moderate in 2 as good and in 2 as very good. The drug failed in 9/11 opiate-pretreated patients. It is suggested that salmon calcitonin pain-relieving activity might depend on the tumor type, previous pain-relieving drug intake and site of metastatic disease.
