Why is Fosavance used? What is it for?
What is FOSAVANCE?
FOSAVANCE is a tablet that contains two active substances, alendronic acid (commonly called alendronate) and colecalciferol, known as vitamin D3.
What is alendronate?
Alendronate belongs to a group of non-hormonal medicines called bisphosphonates. Alendronate prevents bone loss that occurs in postmenopausal women and helps rebuild bone. Alendronate reduces the risk of vertebral and spine fractures. "hip.
What is Vitamin D?
Vitamin D is an essential nutrient required for calcium absorption and bone health. The body can only adequately absorb calcium from food if it has enough vitamin D. Foods that contain vitamin D are very few. The main supply of vitamin D occurs in the summer through exposure to sunlight, which produces vitamin D in the skin. As skin ages, it produces less vitamin D. Too little vitamin D can lead to bone loss and osteoporosis. Severe vitamin D deficiency can cause muscle weakness which can lead to falls and an increased risk of fractures.
What is FOSAVANCE used for?
Your doctor has prescribed FOSAVANCE to treat osteoporosis and to reduce the risk of vitamin D insufficiency. FOSAVANCE reduces the risk of spine and hip fractures in women after menopause.
What is osteoporosis?
Osteoporosis is a thinning and weakening of the bones. It is common in women after menopause. In menopause, the ovaries stop producing the female hormone, estrogen, which helps keep a woman's skeleton healthy. As a result, it occurs. bone loss and bone becomes weaker. The risk of osteoporosis is greater the earlier the woman reaches menopause.
In the early stages, osteoporosis usually has no symptoms. However, if treatment is not taken, fractures can occur. Although fractures are usually painful, fractures of the bones of the spine may not be felt until they are found. in a decrease in stature. Fractures can occur during everyday activities such as lifting weights, or with minor injuries that would generally not be able to cause fractures in normal bone. Fractures normally occur in the hip, spine or wrist and can be not only painful but can lead to significant deformities and disabilities, such as a bowed back (hump) and limitations in movement.
How can osteoporosis be treated?
Along with treatment with FOSAVANCE, your doctor may suggest lifestyle changes to improve your condition, such as: Quitting smoking: Smoking appears to increase the rate at which bone is lost and therefore may increase the risk of fractures.
Exercise Like muscles, bones need exercise to stay strong and healthy. Consult your doctor before starting any exercise program.
Balanced diet The doctor will be able to give information on the diet or on the possible need to take food supplements.
Contraindications When Fosavance should not be used
Do not take FOSAVANCE
- if you are allergic to alendronate sodium trihydrate, cholecalciferol or any of the other ingredients of this medicine
- if you have certain problems with your esophagus (the tube that connects your mouth with your stomach), such as narrowing or difficulty swallowing,
- if you are unable to stand or sit upright for at least 30 minutes,
- if your doctor has told you that you have low levels of calcium in your blood.
If you think that any of these apply to you, do not take the tablets. Consult your doctor and follow the instructions given.

04.0 CLINICAL INFORMATION
04.1 Therapeutic indications
FOSAVANCE is indicated for the treatment of postmenopausal osteoporosis in women at risk of vitamin D insufficiency. FOSAVANCE reduces the risk of vertebral and hip fractures.
04.2 Posology and method of administration
Dosage
The recommended dose is one tablet once a week.
Patients should be advised that if they miss a dose of FOSAVANCE, they should take one tablet on the morning following the day they notice. You should not take two tablets on the same day but you should restart taking one tablet once a week, on the chosen day as previously established.
Due to the nature of the disease process of osteoporosis, FOSAVANCE should be used as a long-term therapy.
The optimal duration of bisphosphonate treatment for osteoporosis has not been established. The need for continued treatment should be reassessed in each individual patient periodically based on the potential benefits and risks of FOSAVANCE, particularly after 5 or more years of use. .
Patients should take calcium supplements if dietary intake is inadequate (see section 4.4). On an individual basis, additional vitamin D supplementation should be considered taking into account all daily vitamin D intake taken with Vitamin and dietary supplements. The equivalence of once weekly intake of 2,800 IU vitamin D3 to FOSAVANCE 400 IU once daily vitamin D has not been studied.
Elderly population
In clinical studies, no age-related difference in the efficacy or safety profiles of alendronate was demonstrated. Therefore, no dose adjustment is necessary in elderly patients.
Patients with kidney damage
FOSAVANCE is not recommended in patients with renal impairment when creatinine clearance is less than 35 ml / min as there is no experience in this regard. No dose adjustment is necessary in patients with a creatinine clearance greater than 35 ml / min.
Pediatric population
The safety and efficacy of FOSAVANCE has not been established in children under the age of 18. FOSAVANCE should not be used in children under the age of 18 as there are no data available for the combination of alendronic acid and colecalciferol. Currently available data for alendronic acid in the pediatric population are described in section 5.1.
Method of administration
Oral use.
To obtain adequate absorption of alendronate:
FOSAVANCE should only be taken with tap water (not mineral water) at least 30 minutes before any food, drink or medicine (including antacids, calcium supplements and vitamins) of the day. Other beverages (including mineral water), food and some medicinal products are likely to reduce the absorption of alendronate (see sections 4.5 and 4.8).
The following instructions must be followed exactly to minimize the risk of oesophageal irritation and related adverse reactions (see section 4.4):
• FOSAVANCE should only be swallowed after getting out of bed to start the day with a full glass of water (not less than 200 ml).
• The patient should only swallow FOSAVANCE whole. The patient should not crush or chew or dissolve the tablet in the mouth due to the potential risk of oropharyngeal ulceration.
• The patient should not lie down for at least 30 minutes after taking FOSAVANCE and as long as they have not eaten anything.
• FOSAVANCE should not be taken at bedtime or before getting out of bed at the start of the day.
04.3 Contraindications
- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.
- Disorders of the esophagus and other factors that delay oesophageal emptying such as stricture or achalasia.
- Inability to stand or sit upright for at least 30 minutes.
- Hypocalcemia.
04.4 Special warnings and appropriate precautions for use
Alendronate
Adverse reactions of the upper gastrointestinal tract
Alendronate may cause local irritation of the upper gastrointestinal mucosa. Due to the potential for worsening of the underlying disease, caution should be exercised when administering alendronate to patients with active upper gastrointestinal disorders, such as dysphagia, esophageal, gastritis, duodenitis, ulcers or with a recent (within the previous year) history of major gastrointestinal disorders such as peptic ulcer or active gastrointestinal bleeding or upper gastrointestinal surgery excluding pyloroplasty (see section 4.3). In patients with Barrett's esophagus already known, prescribers must weigh the potential benefits and risks of alendronate on an individual basis.
Esophageal reactions (some severe and requiring hospitalization) such as esophagitis, esophageal ulcers and esophageal erosions, rarely followed by esophageal strictures, have been reported in patients receiving alendronate. any signs or symptoms that indicate a possible oesophageal reaction and advise the patient to discontinue alendronate and seek medical attention if symptoms of oesophageal irritation such as dysphagia, odynophagia or retrosternal pain or development or worsening of heartburn occur (see section 4.8) .
The risk of serious esophageal adverse reactions appears to be greater in patients who do not take alendronate properly and / or who continue to take alendronate after developing symptoms suggestive of oesophageal irritation. It is very important that the patient knows and understands how to take the drug (see section 4.2). The patient should be advised that if these precautions are not followed, the risk of esophageal problems may increase.
While no increased risk was observed in large clinical trials with alendronate, rare (post-marketing) cases of gastric and duodenal ulcers, some serious and associated with complications, have been reported (see section 4.8). .
Osteonecrosis of the mandible / maxilla
Osteonecrosis of the jaw, usually associated with tooth extraction and / or local infection (including osteomyelitis), has been reported in cancer patients receiving regimens including bisphosphonates administered primarily intravenously. Many of these patients were also treated with chemotherapy and corticosteroids. Osteonecrosis of the jaw has also been reported in patients with osteoporosis being treated with oral bisphosphonates.
When assessing an individual's risk of developing osteonecrosis of the jaw, the following risk factors should be considered:
• potency of bisphosphonate (maximum for zoledronic acid), route of administration (see above) and cumulative dose
• cancer, chemotherapy, radiotherapy, corticosteroids, angiogenesis inhibitors, smoking
• a history of dental disease, poor oral hygiene, periodontal disease, invasive dental procedures and poorly fitting dentures.
Before initiating treatment with oral bisphosphonates in patients with poor dental health, the need for a dental examination with appropriate preventive dental procedures should be considered.
During treatment, these patients should, if possible, avoid invasive dental procedures. In patients who have developed osteonecrosis of the jaw during bisphosphonate therapy, dental surgery may exacerbate the condition. For patients requiring dental procedures, there are no data available to suggest that discontinuation of bisphosphonate treatment reduce the risk of osteonecrosis of the jaw. The clinical judgment of the treating physician must guide the management program of each patient, based on the individual assessment of the risk / benefit ratio.
During treatment with bisphosphonates, all patients should be encouraged to maintain good oral hygiene, to undergo periodic dental check-ups, and to report any type of oral symptoms such as tooth mobility, pain or swelling.
Musculoskeletal pain
Bone, joint and / or muscle pain has been reported in patients receiving bisphosphonates. In post-marketing experience these symptoms have rarely been severe and / or have caused disability (see section 4.8). The timing of symptom onset ranged from one day to several months after initiation of treatment. Discontinuation of treatment resulted in symptom relief in most patients. Following re-administration of the same medicine or another bisphosphonate, a subgroup of patients experienced a relapse of symptoms.
Atypical fractures of the femur
Atypical subtrochanteric and diaphyseal fractures of the femur have been reported, mainly in patients on long-term bisphosphonate therapy for osteoporosis. These short transverse or oblique fractures can occur anywhere in the femur from just below the lesser trochanter to above the supracondylar line. These fractures occur spontaneously or after minimal trauma and some patients experience thigh or groin pain, often associated with imaging evidence of stress fractures, weeks or months before a hip fracture occurs. complete. Fractures are often bilateral; therefore in bisphosphonate-treated patients who have sustained a femoral shaft fracture, the contralateral femur should be examined. Limited healing of these fractures has also been reported. In patients with suspected atypical femoral fracture, consideration should be given to discontinuation of bisphosphonate therapy pending an assessment of the patient based on individual benefit risk.
During treatment with bisphosphonates, patients should be advised to report any pain in the thigh, hip or groin and any patient who exhibits such symptoms should be evaluated for the presence of an incomplete fracture of the femur.
Kidney damage
The use of FOSAVANCE in patients with renal impairment is not recommended when creatinine clearance is less than 35 ml / min (see section 4.2).
Bone and mineral metabolism
Causes of osteoporosis other than estrogen deficiency and age must be carefully considered.
Hypocalcaemia must be corrected before initiating therapy with FOSAVANCE (see section 4.3). Other disorders of mineral metabolism (such as vitamin D deficiency and hypoparathyroidism) should also be treated appropriately before initiating therapy with FOSAVANCE. Vitamin D in FOSAVANCE is not suitable for correcting vitamin D deficiency.In patients with these clinical conditions, monitoring of serum calcium levels and symptoms of hypocalcaemia should be performed during treatment with FOSAVANCE.
Due to the positive effect of alendronate on increased bone mineralization, decreases in serum calcium and phosphate levels may occur especially in patients taking glucocorticoids in whom calcium absorption may be reduced. Such decreases are usually However, there have been rare reports of symptomatic hypocalcaemia, occasionally severe and often in patients with predisposing conditions (eg, hypoparathyroidism, vitamin D deficiency and calcium malabsorption) (see section 4.8).
Cholecalciferol
Vitamin D3 may increase the extent of hypercalcaemia and / or hypercalciuria when administered to patients with diseases associated with irregular overproduction of calcitriol (eg. Leukemia, lymphoma, sarcoidosis). In these patients, serum and serum calcium should be monitored. urinary.
Patients with malabsorption may not adequately absorb vitamin D3.
Excipients
This medicinal product contains lactose and sucrose. Patients with rare hereditary problems of fructose intolerance, galactose intolerance, the Lapp lactase deficiency, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.
04.5 Interactions with other medicinal products and other forms of interaction
Alendronate
Food and beverages (including mineral water), calcium supplements, antacids and other oral medicines, when taken at the same time as alendronate, are likely to interfere with the absorption of alendronate. Consequently, patients should allow at least 30 minutes to elapse after taking alendronate before taking any other medicinal product orally (see sections 4.2 and 5.2).
Since the use of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) is associated with gastrointestinal irritation, caution should be exercised during concomitant treatment with alendronate.
Cholecalciferol
Olestra, mineral oils, orlistat, and bile sequestering agents (eg cholestyramine, colestipol) can hinder the absorption of vitamin D. The anticonvulsants, cimetidine and thiazides can increase the catabolism of vitamin D. Additional vitamin D supplements can be considered on an individual basis.
04.6 Pregnancy and lactation
FOSAVANCE is for use in postmenopausal women only and should therefore not be used during pregnancy or breastfeeding.
Pregnancy
There are no or limited data from the use of alendronate in pregnant women. Animal studies have shown reproductive toxicity. Alendronate caused dystocia due to hypocalcaemia in pregnant rats (see section 5.3). Hypercalcaemia and reproductive toxicity have been observed with high doses of vitamin D in animal studies (see section 5.3) FOSAVANCE should not be used during pregnancy.
Feeding time
It is unknown whether alendronate / metabolites are excreted in human milk. A risk to the newborns / infants cannot be excluded. Alendronate should not be used during breastfeeding. Cholecalciferol and some of its active metabolites pass into breast milk.
Fertility
Bisphosphonates are incorporated into the bone matrix, from which they are gradually released over a period of years. The amount of bisphosphonates incorporated into adult bone, and therefore, the amount available for release into the systemic circulation, is directly related to the dose and duration of bisphosphonate use (see section 5.2). There are no data on risk. fetal in man. However, there is a theoretical risk of fetal harm, mainly skeletal, if a woman becomes pregnant after completing a course of bisphosphonate therapy. The impact on risk of variables such as the time from cessation of bisphosphonate therapy to conception, the type of bisphosphonate used, and the route of administration (intravenous versus oral) has not been studied.
04.7 Effects on ability to drive and use machines
FOSAVANCE may have moderate influence on the ability to drive and use machines in patients who experience certain adverse reactions (eg blurred vision, dizziness and severe bone, muscle or joint pain (see section 4.8)).
04.8 Undesirable effects
Summary of the safety profile
The most commonly reported adverse reactions are upper gastrointestinal adverse reactions including abdominal pain, dyspepsia, oesophageal ulcer, dysphagia, abdominal distension and acid regurgitation (> 1%).
Table of adverse reactions
The following adverse reactions come from clinical studies and / or from the use of alendronate after its marketing.
No further adverse reactions were identified with the combination of alendronate and cholecalciferol.
Frequencies are defined as: very common (≥ 1/10), common (≥ 1/100 to
Reporting of suspected adverse reactions
The reporting of suspected adverse reactions that occur after the authorization of the medicinal product is important, as it allows continuous monitoring of the benefit / risk ratio of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Italian Medicines Agency. , website: www.aifa.gov.it/responsabili
04.9 Overdose
Alendronate
Symptoms
Hypocalcaemia, hypophosphataemia and upper gastrointestinal adverse reactions, such as gastric disturbance, heartburn, esophagitis, gastritis or ulcer, may be the consequence of oral overdose.
Management
No specific information is available on the treatment of overdose with alendronate. In case of overdose with FOSAVANCE, give milk or antacids that bind to alendronate. Due to the risk of oesophageal irritation, do not induce vomiting and keep the patient strictly erect.
Cholecalciferol
Vitamin D toxicity has not been documented during chronic therapy in generally healthy adults at a dose below 10,000 IU / day. In a clinical study of healthy adults, a daily dose of 4,000 IU of vitamin D3 for up to five months was not associated with hypercalciuria or hypercalcemia.
05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: drugs for the treatment of bone diseases, bisphosphonates, combinations.
ATC code: M05BB03.
FOSAVANCE is a combination tablet containing the two active substances alendronate sodium trihydrate and colecalciferol (vitamin D3).
Mechanism of action
Alendronate
Alendronate sodium is a bisphosphonate which acts as a specific inhibitor of osteoclast-mediated bone resorption with no direct effect on bone formation. Preclinical studies have shown that alendronate preferentially localizes to sites of active resorption. Activity is inhibited, but osteoclast recruitment and adhesion are not altered. The bone tissue formed during treatment with alendronate is qualitatively normal.
Cholecalciferol (vitamin D3)
Vitamin D3 is produced in the skin through the conversion of 7-dehydrocholesterol to vitamin D3 by ultraviolet light. In the absence of adequate exposure to sunlight, vitamin D3 is an essential nutrient. Vitamin D3 is converted to 25-hydroxyvitamin D3 in the liver and stored for the needs of the body. Conversion in the kidney to 1,25-dihydroxyvitamin D3 (calcitriol), the active form of the hormone that mobilizes calcium, is subjected to tight adjustment. The main activity of 1,25-dihydroxyvitamin D3 is to increase the absorption of both calcium and phosphate in the intestine and to regulate serum calcium, the renal excretion of calcium and phosphate, the formation of bone and bone resorption.
Vitamin D3 is needed for normal bone formation. Vitamin D insufficiency occurs when both exposure to sunlight and dietary intake are inadequate. Insufficiency is associated with a negative calcium balance, bone loss, and increased risk of skeletal fracture. In severe cases, the deficiency results in secondary hyperparathyroidism, hypophosphataemia, proximal muscle weakness and osteomalacia, thus increasing the risk of falls and fractures in people with osteoporosis Vitamin D supplements reduce these risks and their consequences.
Osteoporosis is defined as bone mineral density (BMD) of the spine or hip that is 2.5 standard deviations (SD) less than the mean value in a normal young population or as a history of fragility fracture, regardless of BMD .
Clinical efficacy and safety
Studies on FOSAVANCE
The effect of FOSAVANCE (alendronate 70 mg / vitamin D3 2,800 IU) on vitamin D parameters was demonstrated in a 15-week multinational study enrolling 682 postmenopausal women with osteoporosis (serum 25-hydroxyvitamin D at baseline: mean 56 nmol / l [22.3 ng / ml]; range 22.5-225 nmol / l [9-90 ng / ml]). Patients were treated with the lower dose formulation (70 mg / 2,800 IU) of FOSAVANCE (n = 350) or with FOSAMAX (alendronate) 70 mg (n = 332) once weekly; additional vitamin D supplements were prohibited. After 15 weeks of treatment, mean levels of 25-hydroxyvitamin D serum were significantly higher (26%) in the FOSAVANCE group (70 mg / 2,800 IU) (56 nmol / l [23 ng / ml]) than in the group treated with alendronate alone (46 nmol / l [18.2 ng / ml]) The percentage of patients with vitamin D insufficiency (serum 25-hydroxyvitamin D
Studies on alendronate
Therapeutic equivalence of alendronate 70 mg once weekly (n = 519) and alendronate 10 mg / day (n = 370) was demonstrated in a one-year multicenter study of postmenopausal women with osteoporosis. Mean increases in BMD from baseline in the lumbar spine at one year was 5.1% (95% CI: 4.8, 5.4%) in the 70 mg once weekly group and 5.4% ( 95% CI: 5.0, 5.8%) in the 10 mg / day group. Mean increases in BMD were 2.3% and 2.9% at the femoral neck and 2, 9% and 3.1% across the hip, for the 70 mg once weekly and 10 mg once daily groups, respectively. The two treatment groups were also similar with regard to increases in DMO in other bone districts.
The effects of alendronate on bone mass and fracture incidence in postmenopausal women were examined in two initial efficacy studies of identical design (n = 994) and in the Fracture Intervention Trial (FIT: n = 6,459). ).
In the initial efficacy studies, the mean increases in BMD with alendronate 10 mg / day compared to placebo at three years were 8.8%, 5.9%, and 7.8% at the spine, spine, neck of the femur and trochanter. Even the organism's DMO in toto it increased significantly. C "was a reduction of 48% (alendronate 3.2% vs placebo 6.2%) in the proportion of alendronate-treated patients with one or more vertebral fractures compared to those treated with placebo. In the two-year extension of these studies, BMD continued to increase in the spine and trochanter and remained stable in the femoral neck and body. in toto.
The FIT consists of two placebo-controlled studies of alendronate once daily (5 mg per day for two years and 10 mg per day for one or two additional years):
• FIT 1: A three-year study of 2,027 patients with at least one vertebral (compression) fracture at baseline. In this study, daily intake of alendronate reduced the incidence of ≥1 new vertebral fracture by 47% (alendronate 7.9% vs placebo 15.0%). There was also a statistically significant reduction in the incidence of hip fractures (1.1% vs 2.2%, a reduction of 51%).
• FIT 2: A four-year study of 4,432 patients with low bone mass but without vertebral fractures at baseline. In this study, a significant difference was observed in the subgroup analysis of osteoporotic women (37% of the overall study population, with osteoporosis as defined above) in the incidence of hip fractures (alendronate 1.0% vs placebo 2.2%, a reduction of 56%) and in the incidence of ≥1 vertebral fracture (2.9% vs 5.8%, a reduction of 50%).
Laboratory data
In clinical trials, asymptomatic, mild and transient decreases in serum calcium and phosphate were reported in approximately 18% and 10% of patients treated with alendronate 10 mg / day, respectively, compared with approximately 12% and 3% of those treated with placebo. . However, the incidences of serum calcium decreases up to
Pediatric population
Alendronate sodium has been studied in a small number of patients under the age of 18 with osteogenesis imperfecta. The results are insufficient to support the use of alendronate sodium in pediatric patients with osteogenesis imperfecta.
05.2 Pharmacokinetic properties
Alendronate
Absorption
Compared to an intravenous reference dose, the mean oral bioavailability of alendronate in women was 0.64% for doses ranging from 5 mg to 70 mg administered after an overnight fast and 2 hours before a standardized breakfast. Likewise, bioavailability decreased to approximately 0.46% and 0.39% when alendronate was administered an "hour or half" before a standardized breakfast. In osteoporosis studies, alendronate was effective when given at least 30 minutes before the first food or drink of the day.
The alendronate contained in the FOSAVANCE combination tablet (70 mg / 2,800 IU) is bioequivalent to one alendronate 70 mg tablet.
Bioavailability was negligible when alendronate was administered with or within two hours of a standardized breakfast. Concomitant administration of coffee or orange juice with alendronate reduced its bioavailability by approximately 60%.
In healthy subjects, prednisone administered orally (20 mg three times daily for five days) did not produce clinically relevant changes in the oral bioavailability of alendronate (a mean increase of 20% to 44%).
Distribution
Studies in rats show that following intravenous administration of 1 mg / kg l "alendronate, initially distributed in soft tissues, is rapidly redistributed to bone or excreted in the urine. In humans, the mean volume of distribution at steady state, exclusive of bone, is at least 28 liters. Plasma concentrations of alendronate following therapeutic oral doses are too low to be analytically detected (plasma protein is approximately 78%.
Biotransformation
In both humans and animals, there is no evidence that alendronate is metabolised.
Elimination
Following a single intravenous dose of 14C-labeled alendronate, approximately 50% of the radioactivity was excreted in the urine within 72 hours and little or no radioactivity was recovered in the faeces. After single intravenous administration of 10 mg, the clearance renal of alendronate was 71 ml / min and the clearance systemic did not exceed 200 ml / min. Plasma concentrations fell by more than 95% within 6 hours of intravenous administration. The terminal half-life in humans has been estimated to exceed ten years, reflecting the release of alendronate from the skeleton.
In rats, renal excretion of alendronate does not occur via acid-base transport systems and therefore is not expected to interfere at this level with the excretion of other medicinal products in humans.
Cholecalciferol
Absorption
In healthy adults (of both sexes) following administration of FOSAVANCE in the morning on an empty stomach and two hours before a meal, the mean area under the serum concentration-time curve (AUC0-120 h) for vitamin D3 (not adjusted for endogenous vitamin D3 levels) was 296.4 ng • h / mL. The mean maximum serum concentration (Cmax) of vitamin D3 was 5.9 ng / mL, and the median time required to reach maximum serum concentration (Tmax) was 12 hours The bioavailability of the 2,800 IU vitamin D3 in FOSAVANCE is similar to the 2,800 IU vitamin D3 given alone.
Distribution
After absorption, vitamin D3 enters the bloodstream carried by chylomicrons. Vitamin D3 is rapidly distributed mostly in the liver where it is metabolized to 25-hydroxyvitamin D3, the main reserve form. More negligible quantities are distributed to adipose tissues. and muscle and stored at these sites as vitamin D3 for later release into the circulation.Circulating vitamin D3 is bound to vitamin D binding protein.
Biotransformation
Vitamin D3 is rapidly metabolized by hydroxylation in the liver to 25-hydroxyvitamin D3, and subsequently metabolized in the kidney to 1,25-dihydroxyvitamin D3, which is the biologically active form. Further hydroxylation takes place prior to elimination. A small percentage of vitamin D3 undergoes glucuronidation before being eliminated.
Elimination
When radioactive vitamin D3 was administered to healthy people, the mean urinary excretion of radioactivity after 48 hours was 2.4%, and the mean faecal excretion of radioactivity after 4 days was 4.9%. In both cases, the excreted radioactivity was found to derive almost exclusively from the metaboltites of the original molecule. The mean half-life of serum vitamin D3 following an oral dose of FOSAVANCE (70 mg / 2,800 IU) is approximately 24 hours.
Kidney damage
Preclinical studies show that alendronate which does not settle in bone is rapidly excreted in the urine. There was no evidence of saturation of bone uptake following chronic administration of cumulative intravenous doses up to 35 mg / kg in animals.
Although no clinical information is available, it is likely that, as in animals, renal elimination of alendronate will be reduced in patients with impaired renal function. Consequently, slightly greater accumulation of alendronate in bone might be expected in patients. with impaired renal function (see section 4.2).
05.3 Preclinical safety data
Non-clinical studies have not been conducted with the combination of alendronate and cholecalciferol.
Alendronate
Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity and carcinogenic potential. Studies in rats have shown that alendronate treatment during pregnancy is associated with dystocia linked to hypocalcaemia in mothers during parturition. In studies, rats given the highest doses showed a higher incidence of incomplete fetal ossification. The relevance of these finds to man is not known.
Cholecalciferol
At doses well above the therapeutic range, reproductive toxicity has been observed in animal studies.
