⛔ Contraindications ▾
4 CONTRAINDICATIONS Hypersensitivity to calcitonin-salmon or any of the excipients. Reactions have included anaphylactic shock, anaphylaxis, bronchospasm, and swelling of the tongue or throat [see Warnings and Precautions ( 5.1 ) ]. Hypersensitivity to calcitonin-salmon or any of the excipients (4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Serious hypersensitivity reactions including anaphylactic shock have been reported. Consider skin testing prior to treatment in patients with suspected hypersensitivity to calcitonin-salmon ( 5.1 ) Hypocalcemia has been reported. Ensure adequate intake of calcium and vitamin D ( 5.2 ) Nasal adverse reactions, including severe ulceration can occur.
Periodic nasal examinations are recommended ( 5.3 ) Malignancy: A meta-analysis of 21 clinical trials suggests an increased risk of overall malignancies in calcitonin-salmon-treated patients ( 5.4 , 6.1 ) Circulating antibodies to calcitonin-salmon may develop, and may cause loss of response to treatment ( 5.5 )
5.1Hypersensitivity Reactions Serious hypersensitivity reactions have been reported in patients receiving Calcitonin Salmon Nasal Solution, e.g., bronchospasm, swelling of the tongue or throat, anaphylaxis and anaphylactic shock. Reports of serious hypersensitivity reactions with injectable calcitonin-salmon have also been reported, including reports of death attributed to anaphylaxis. The usual provisions should be made for emergency treatment if such a reaction occurs.
Hypersensitivity reactions should be differentiated from generalized flushing and hypotension [see Contraindications ( 4 ) ]. For patients with suspected hypersensitivity to calcitonin-salmon, skin testing should be considered prior to treatment utilizing a dilute, sterile solution of a calcitonin-salmon injectable product. Healthcare providers may wish to refer patients who require skin testing to an allergist.
A detailed skin testing protocol is available from the Medical Services Department of Par Health at 1-800-828-9393.
5.2Hypocalcemia Hypocalcemia associated with tetany (i.e., muscle cramps, twitching) and seizure activity has been reported with calcitonin therapy. Hypocalcemia must be corrected before initiating therapy with Calcitonin Salmon Nasal Solution. Other disorders affecting mineral metabolism (such as vitamin D deficiency) should also be effectively treated.
In patients with these conditions, serum calcium and symptoms of hypocalcemia should be monitored during therapy with Calcitonin Salmon Nasal Solution. Use of Calcitonin Salmon Nasal Solution is recommended in conjunction with an adequate intake of calcium and vitamin D [see Dosage and Administration ( 2.3 ) ].
5.3Nasal Adverse Reactions Adverse reactions related to the nose including rhinitis and epistaxis have been reported. Development of mucosal alterations may occur. Therefore, periodic nasal examinations with visualization of the nasal mucosa, turbinates, septum and mucosal blood vessels are recommended prior to start of treatment with Calcitonin Salmon Nasal Solution, periodically during the course of therapy, and at any time nasal symptoms occur.
Calcitonin Salmon Nasal Solution should be discontinued if severe ulceration of the nasal mucosa occurs, as indicated by ulcers greater than 1.5 mm in diameter or penetrating below the mucosa, or those associated with heavy bleeding. Although smaller ulcers often heal without withdrawal of Calcitonin Salmon Nasal Solution, medication should be discontinued temporarily until healing occurs [see Adverse Reactions (6.1 ) ].
5.4Malignancy In a meta-analysis of 21 randomized, controlled clinical trials with calcitonin-salmon (nasal solution or investigational oral formulations), the overall incidence of malignancies reported was higher among calcitonin-salmon-treated patients (4.1%) compared with placebo-treated patients (2.9%). This suggests an increased risk of malignancies in calcitonin-salmon-treated patients compared to placebo-treated patients. The benefits for the individual patient should be carefully considered against possible risks [see Adverse Reactions ( 6.1 ) ].
5.5Antibody Formation Circulating antibodies to calcitonin-salmon have been reported with Calcitonin Salmon Nasal Solution. The possibility of antibody formation should be considered in an… [Excerpted — this section continues on DailyMed.]

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Calcitonin Salmon Nasal Solution in the treatment of postmenopausal osteoporosis was assessed in 5 randomized, double-blind, placebo controlled trials that enrolled postmenopausal women, aged 45 to 75 years. The duration of the trials ranged from 1 to 2 years.
The incidence of adverse reactions reported in studies involving postmenopausal osteoporotic patients chronically exposed to Calcitonin Salmon Nasal Solution (N=341) and to placebo nasal solution (N=131), and reported in greater than 3% of Calcitonin Salmon Nasal Solution treated patients are presented in the following table. Other than flushing, nausea, possible allergic reactions, and possible local irritative effects in the respiratory tract, a relationship to Calcitonin Salmon Nasal Solution has not been established.
Table 1: Adverse Reactions Occurring in at Least 3% of Postmenopausal Patients Treated with Calcitonin Salmon Nasal Solution † Symptom of nose includes: nasal crusts, dryness, redness or erythema, nasal sores, irritation, itching, thick feeling, soreness, pallor, infection, stenosis, runny/blocked, small wound, bleeding wound, tenderness, uncomfortable feeling and sore across bridge of nose. Calcitonin Salmon Nasal Solution Placebo Nasal Solution Adverse Reaction N = 341 % of Patients N = 131 % of Patients Rhinitis 12 7 Symptom of Nose † 11 16 Back Pain 5 2 Arthralgia 4 5 Epistaxis 4 5 Headache 3 5 Nasal Adverse Reactions: In all postmenopausal patients treated with Calcitonin Salmon Nasal Solution, the most commonly reported nasal adverse reactions included rhinitis (12%), epistaxis (4%), and sinusitis (2%).
Smoking did not have a contributory effect on the occurrence of nasal adverse reactions. Adverse reactions reported in 1% to 3% of patients treated with Calcitonin Salmon Nasal Solution include: influenza-like symptoms, erythematous rash, arthrosis, myalgia, sinusitis, upper respiratory tract infection, bronchospasm, abdominal pain, nausea, dizziness, paresthesia, abnormal lacrimation, conjunctivitis, lymphadenopathy, infection, and depression. Malignancy A meta-analysis of 21 randomized, controlled clinical trials with calcitonin-salmon (nasal solution or investigational oral formulations) was conducted to assess the risk of malignancies in calcitonin-salmon-treated patients compared to placebo-treated patients.
The trials in the meta-analysis ranged in duration from 6 months to 5 years and included a total of 10883 patients (6151 treated with calcitonin-salmon and 4732 treated with placebo). The overall incidence of malignancies reported in these 21 trials was higher among calcitonin-salmon-treated patients (254/6151 or 4.1%) compared with placebo-treated patients (137/4732 or 2.9%). Findings were similar when analyses were restricted to the 18 nasal spray only trials [calcitonin-salmon 122/2712 (4.5%); placebo 30/1309 (2.3%)].
The meta-analysis results suggest an increased risk of overall malignancies in calcitonin-salmon-treated patients compared to placebo-treated patients when all 21 trials are included… [Excerpted — this section continues on DailyMed.]

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS There are no data to support use in children (8.4) Nasal reactions are more common in elderly patients ( 8.5 )
8.1Pregnancy Risk Summary Calcitonin Salmon Nasal Solution is not indicated for use in females of reproductive potential. There are no data with the use of Calcitonin Salmon Nasal Solution in pregnant women. In an animal reproduction study, subcutaneous administration of calcitonin-salmon to pregnant rabbits during organogenesis at 4 to 18 times the recommended parenteral human dose caused a decrease in fetal birth weights.
No adverse developmental outcome was observed in the rat with subcutaneous administration of calcitonin-salmon at 9 times the recommended human parenteral dose based on body surface area (see Data ). Data Animal Data Calcitonin-salmon has been shown to cause a decrease in fetal birth weights in rabbits when given by subcutaneous injection in doses 4 to 18 times the parenteral dose (of 54 International Units/m 2 ) and 70 to 278 times the intranasal dose recommended for human use based on body surface area. No embryo/fetal toxicities related to Calcitonin Salmon Nasal Solution were reported from maternal subcutaneous daily doses in rats up to 80 International Units/kg/day from gestation day 6 to 15.
8.2Lactation Risk Summary Calcitonin Salmon Nasal Solution is not indicated for use in females of reproductive potential. There is no information on the presence of calcitonin-salmon in human milk, the effects on the breastfed child, or the effects on milk production. Calcitonin has been shown to inhibit lactation in rats.
8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established.
8.5Geriatric Use In a multi-centered, double-blind, randomized clinical study of calcitonin-salmon nasal solution, 279 patients were less than 65 years old, while 467 patients were 65 to 74 years old and 196 patients were 75 years old and older. Compared to subjects less than 65 years old, the incidence of nasal adverse reactions (rhinitis, irritation, erythema, and excoriation) was higher in patients over the age of 65, particularly among those over the age of 75. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

Single doses of Calcitonin Salmon Nasal Solution up to 1600 International Units, doses up to 800 International Units per day for 3 days and chronic administration of doses up to 600 International Units per day have been studied without serious adverse effects.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Calcitonin-salmon is a calcitonin receptor agonist. Calcitonin-salmon acts primarily on bone, but direct renal effects and actions on the gastrointestinal tract are also recognized. Calcitonin-salmon appears to have actions essentially identical to calcitonins of mammalian origin, but its potency per mg is greater and it has a longer duration of action.
The actions of calcitonin on bone and its role in normal human bone physiology are still not completely elucidated, although calcitonin receptors have been discovered in osteoclasts and osteoblasts.
12.2Pharmacodynamics The information below, describing the clinical pharmacology of calcitonin, has been derived from studies with injectable calcitonin-salmon. The mean bioavailability of calcitonin-salmon nasal solution is approximately 3% of the injectable calcitonin-salmon in healthy subjects and, therefore, the conclusions concerning the clinical pharmacology of this preparation may be different. Bone Single injections of calcitonin-salmon caused a marked transient inhibition of the ongoing bone resorptive process.
With prolonged use, there is a persistent, smaller decrease in the rate of bone resorption. Histologically, this is associated with a decreased number of osteoclasts and an apparent decrease in their resorptive activity. In healthy adults, who have a relatively low rate of bone resorption, the administration of exogenous calcitonin‑salmon results in decreases in serum calcium within the limits of the normal range.
In healthy children and in patients whose bone resorption is more rapid, decreases in serum calcium are more pronounced in response to calcitonin-salmon. Kidney Studies with injectable calcitonin-salmon show increases in the excretion of filtered phosphate, calcium, and sodium by decreasing their tubular reabsorption. Comparable studies have not been conducted with Calcitonin Salmon Nasal Solution.
Gastrointestinal Tract Some evidence from studies with injectable preparations suggests that calcitonin-salmon may have effects on the gastrointestinal tract. Short-term administration of injectable calcitonin-salmon results in marked transient decreases in the volume and acidity of gastric juice and in the volume and the trypsin and amylase content of pancreatic juice. Whether these effects continue to be elicited after each injection of calcitonin-salmon during chronic therapy has not been investigated.
These studies have not been conducted with Calcitonin Salmon Nasal Solution. Calcium Homeostasis In two clinical studies designed to evaluate the pharmacodynamic response to calcitonin-salmon nasal solution, administration of calcitonin-salmon 100 to 1600 International Units to healthy volunteers resulted in rapid and sustained decreases within the normal range for both total serum calcium and serum ionized calcium. Single doses of calcitonin-salmon greater than 400 International Units did not produce any further biological response to the drug.
12.3Pharmacokinetics The bioavailability of Calcitonin Salmon Nasal Solution relative to intramuscular administration in healthy volunteers is between 3% and 5%. Calcitonin Salmon Nasal Solution is absorbed rapidly by the nasal mucosa with a mean T max of about 13 minutes. The terminal half-life of calcitonin-salmon has been calculated to be around 18 minutes and no evidence of accumulation was observed with multiple dosing.

There is no information on the presence of calcitonin-salmon in human milk, the effects on the breastfed child, or the effects on milk production. Calcitonin has been shown to inhibit lactation in rats.
🧬 Pharmacokinetics ▾
12.3Pharmacokinetics The bioavailability of Calcitonin Salmon Nasal Solution relative to intramuscular administration in healthy volunteers is between 3% and 5%. Calcitonin Salmon Nasal Solution is absorbed rapidly by the nasal mucosa with a mean T max of about 13 minutes. The terminal half-life of calcitonin-salmon has been calculated to be around 18 minutes and no evidence of accumulation was observed with multiple dosing.
🧬 Pharmacodynamics ▾
12.2Pharmacodynamics The information below, describing the clinical pharmacology of calcitonin, has been derived from studies with injectable calcitonin-salmon. The mean bioavailability of calcitonin-salmon nasal solution is approximately 3% of the injectable calcitonin-salmon in healthy subjects and, therefore, the conclusions concerning the clinical pharmacology of this preparation may be different. Bone Single injections of calcitonin-salmon caused a marked transient inhibition of the ongoing bone resorptive process.
With prolonged use, there is a persistent, smaller decrease in the rate of bone resorption. Histologically, this is associated with a decreased number of osteoclasts and an apparent decrease in their resorptive activity. In healthy adults, who have a relatively low rate of bone resorption, the administration of exogenous calcitonin‑salmon results in decreases in serum calcium within the limits of the normal range.
In healthy children and in patients whose bone resorption is more rapid, decreases in serum calcium are more pronounced in response to calcitonin-salmon. Kidney Studies with injectable calcitonin-salmon show increases in the excretion of filtered phosphate, calcium, and sodium by decreasing their tubular reabsorption. Comparable studies have not been conducted with Calcitonin Salmon Nasal Solution.
Gastrointestinal Tract Some evidence from studies with injectable preparations suggests that calcitonin-salmon may have effects on the gastrointestinal tract. Short-term administration of injectable calcitonin-salmon results in marked transient decreases in the volume and acidity of gastric juice and in the volume and the trypsin and amylase content of pancreatic juice. Whether these effects continue to be elicited after each injection of calcitonin-salmon during chronic therapy has not been investigated.
These studies have not been conducted with Calcitonin Salmon Nasal Solution. Calcium Homeostasis In two clinical studies designed to evaluate the pharmacodynamic response to calcitonin-salmon nasal solution, administration of calcitonin-salmon 100 to 1600 International Units to healthy volunteers resulted in rapid and sustained decreases within the normal range for both total serum calcium and serum ionized calcium. Single doses of calcitonin-salmon greater than 400 International Units did not produce any further biological response to the drug.
🔬 Clinical Studies ▾
14 CLINICAL STUDIES Two randomized, placebo-controlled, two-year trials were conducted in 266 postmenopausal women who were greater than 5 years postmenopause with spinal, forearm or femoral bone mineral density (BMD) at least one standard deviation below the normal value for healthy premenopausal women (T-score < -1). In both studies, a total of 144 patients received Calcitonin Salmon Nasal Solution 200 International Units or placebo daily. The intent-to-treat population comprised 139 patients who had at least one follow-up BMD measurement.
In study 1, patients also received 500 mg daily calcium supplements, while in study 2, patients received no calcium supplementation. The primary endpoint for both studies was percent change in lumbar spine BMD at 2 years. Calcitonin Salmon Nasal Solution increased lumbar vertebral BMD relative to placebo in women with low bone mass who were greater than 5 years postmenopause (see Table 3 below).
Table 3: Calcitonin Salmon Nasal Solution: Lumbar Spine Bone Mineral Density In Women Greater Than 5 years Postmenopause With Low Bone Mass Lumbar Spine Bone Mineral Density, Mean Change From Baseline (in %) at Month 24 Study 1 (with calcium supplement) n (ITT) = 100 Study 2 (no calcium supplement) n (ITT) = 39 Calcitonin Salmon Nasal Solution 200 IU NS daily +1.56 +1.02 Placebo +0.20 -1.85 Treatment Difference +1.36 +2.87 p-value † < 0.05 < 0.005 ITT: Intent To Treat IU: International Units NS: nasal solution † p-values by parametric testing (2-tailed 2-sample t-test) No effects of calcitonin-salmon nasal solution on cortical bone of the forearm or hip were demonstrated.
In clinical studies of postmenopausal osteoporosis, bone biopsy and radial bone mass assessments at baseline and after 26 months of daily injectable calcitonin-salmon indicate that calcitonin therapy results in the formation of normal bone.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity The incidence of pituitary adenomas was increased in rats after one and two years of subcutaneous exposure to synthetic calcitonin-salmon. The significance of this finding to humans is unknown because pituitary adenomas are very common in rats as they age, the pituitary adenomas did not transform into metastatic tumors, there were no other clear treatment-related neoplasms, and synthetic calcitonin-salmon related neoplasms were not observed in mice after two years of dosing.
Rat findings : The only clear neoplastic finding in rats dosed subcutaneously with synthetic calcitonin-salmon was an increase in the incidence of pituitary adenomas in male Fisher 344 rats and female Sprague Dawley rats after one year of dosing and male Sprague Dawley rats dosed for one and two years. In female Sprague Dawley rats, the incidence of pituitary adenomas after two years was high in all treatment groups (between 80% and 92% including the control groups) such that a treatment-related effect could not be distinguished from natural background incidence.
The lowest dose in male Sprague Dawley rats that developed an increased incidence of pituitary adenomas after two years of dosing (1.7 International Units/kg/day) is approximately 2 times the maximum recommended intranasal dose in humans (200 International Units/day) based on body surface area conversion between rats and humans and a 20-fold conversion factor to account for decreased clinical exposure via the intranasal route. The findings suggest that calcitonin-salmon reduced the latency period for development of non-functioning pituitary adenomas.
Mouse findings : No carcinogenicity potential was evident in male or female mice dosed subcutaneously for two years with synthetic calcitonin-salmon at doses up to 800 International Units/kg/day. The 800 International Units/kg/day dose is approximately 390 times the maximum recommended intranasal dose in humans (200 International Units) based on scaling for body surface area and a 20-fold conversion factor to account for low clinical exposure via the intranasal route. Mutagenesis Synthetic calcitonin-salmon tested negative for mutagenicity using Salmonella typhimurium (5 strains) and Escherichia coli (2 strains), with and without rat liver metabolic activation, and was not clastogenic in a chromosome aberration test in Chinese Hamster V79 cells.
There was no evidence that calcitonin- salmon was clastogenic in the in vivo mouse micronucleus test. Fertility Effects of calcitonin-salmon on fertility have not been assessed in animals.
