Bonasol 70mg Weekly oral solution

Why is Bonasol used? What is it for?

Bonasol oral solution belongs to a group of non-hormonal medicines called bisphosphonates. Bonasol oral solution is used for:

  • Prevent bone loss (osteoporosis) that occurs in postmenopausal women and helps rebuild bone.
  • Reduce the risk of vertebral and hip fractures.

Your doctor has prescribed Bonasol oral solution to treat your osteoporosis and to reduce the risk of vertebral and hip fractures.

What is osteoporosis?

Osteoporosis is a thinning and weakening of the bones. It is common in women after menopause. With menopause, the ovaries stop producing the female hormone estrogen, which helps keep women's skeletons healthy. As a result, bone loss occurs and bones weaken. The earlier a woman enters menopause, the greater the risk of osteoporosis.

Osteoporosis usually has no symptoms at first. However, if left untreated, it can result in bone fractures. Although such fractures usually produce pain, vertebral fractures can also go unnoticed until they cause a decrease in stature. Bone fractures can occur during normal daily activities such as lifting a weight, or as a result of minor injuries, which generally would not cause a fracture in normal bones. Bone fractures usually occur in the hip, spine, or wrist and can not only be painful but can also lead to significant problems such as bowing of the back (hump) and limited range of motion.

How can osteoporosis be treated?

Osteoporosis can be cured and it is never too late to start treatment. Alendronate not only prevents bone loss, it also helps to rebuild any lost bone tissue, and reduces the risk of vertebral and bone fractures. hip.

In addition to treatment with Bonasol Oral Solution, your doctor may suggest that you change your lifestyle for your own good, for example:

Quitting smoking. Smoking appears to increase the rate of bone loss, and consequently, may increase the risk of fractures.

For oral administration.

The recommended dosage is one unit dose of 70 mg (100 ml) once weekly.

The optimal duration of bisphosphonate treatment for osteoporosis has not been established. The need for continued treatment should be reassessed periodically in each individual patient based on the potential benefits and risks of Bonasol 70 mg Oral Solution weekly, particularly after 5 or more years of use.

Method of administration

To allow for adequate absorption of alendronate.

Bonasol 70 mg weekly oral solution it must be taken at least 30 minutes before ingesting any food, drink or medicine of the day, accompanied only by tap water. Other beverages (including mineral water), foods and medicines are likely to reduce the absorption of alendronate (see section 4.5).

To facilitate transit in the stomach, thus reducing the possibility of local and esophageal irritation and any undesirable effects (see section 4.4)

Use in elderly patients: Clinical studies did not reveal any age-related difference in the efficacy or safety profiles of alendronate. Therefore no dosage adjustment is necessary in elderly patients.

Use in the presence of kidney damage: No dosage adjustment is necessary in patients with glomerular filtration rate (GFR) greater than 35 mL / min. Administration of alendronate is not recommended in patients with renal impairment when the GFR is less than 35 ml / min due to lack of experience in this regard.

Use in children and adolescents: The use of alendronate is not recommended in children and adolescents below 18 years of age due to insufficient data on safety and efficacy in conditions associated with pediatric osteoporosis (see also section 5.1).

See also section 4.4 "Special warnings and precautions for use".

04.4 Special warnings and appropriate precautions for use -

Adverse reactions affecting the upper gastrointestinal tract

Bonasol weekly oral solution can cause local irritation of the upper gastrointestinal mucosa. As the potential for aggravation of the underlying disease exists, caution should be exercised when administering Bonasol weekly to patients with upper digestive tract problems such as dysphagia, esophageal disease, gastritis, duodenitis or ulcers, or to patients with a recent "medical history" (within the last year) of major digestive disease such as peptic ulcer, or active gastrointestinal bleeding, or who have undergone upper digestive tract surgery (except for pyloroplasty) (see section 4.3). For patients with Barrett's esophagus, prescribers should weigh the potential benefits and risks of alendronate on an individual basis.

Esophageal reactions (sometimes severe and requiring hospitalization) such as esophagitis, ulcers and esophageal erosions, rarely followed by esophageal stricture, have been reported in patients taking alendronate. Therefore, the physician should pay particular attention to the appearance of any signs or symptoms that indicate a possible esophageal reaction and advise the patient to discontinue treatment with alendronate and to seek medical attention if symptoms of esophageal irritation such as dysphagia occur. pain when swallowing or retrosternal pain, or new or worsening heartburn.

The risk of serious oesophageal adverse events is 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 is well acquainted with and understands how to take the medicinal product (see section 4.2 "Posology and method of administration"). Patients should be advised that failure to follow these instructions may increase the risk of oesophageal problems.

Although no increased risk was observed in large clinical trials, rare (post-marketing) cases of gastric and duodenal ulcers, some severe and associated with complications, have been reported.

Osteonecrosis of the mandible / maxilla

Cases of osteonecrosis of the jaw, usually associated with tooth extraction and / or local infection (including osteomyelitis), have been observed in cancer patients treated with therapeutic regimens that included bisphosphonates administered mainly 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.

The following risk factors should be considered when assessing the individual risk of developing osteonecrosis of the jaw:

• potency of the bisphosphonate (maximum for zoledronic acid), route of administration (see above) and cumulative dose

• cancer, chemotherapy, radiotherapy, corticosteroids, smoking

• history of dental disease, poor oral hygiene, periodontal disease, invasive dental procedures and poorly fitting dentures

Before initiating treatment with oral bisphosphonates in patients in poor dental health the need for a dental examination with appropriate preventive dental procedures should be considered.

During treatment, these patients should avoid invasive dental procedures as much as possible. In patients who develop osteonecrosis of the jaw during bisphosphonate therapy, dental surgery can aggravate their condition. For patients requiring dental surgery, there are no data to suggest that discontinuation of bisphosphonate treatment may reduce the risk of osteonecrosis of the jaw. Clinical judgment of the physician should guide each patient's management program. on the basis of the individual assessment of the risk / benefit ratio.

During bisphosphonate treatment 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 mobility, pain or dental swelling.

Musculoskeletal pain

Pain in the bones, joints and muscles has been reported in patients treated with bisphosphonates. In post-marketing experience these symptoms have rarely been severe and / or disabling (see section "4.8). The time to onset of symptoms ranged from one day to several months after initiation of treatment. Most patients reported symptom relief after discontinuation of the drug. A subset of patients experienced relapse of symptoms after stopping the drug. the same medicine or a different bisphosphonate again.

Atypical fractures of the femur

Atypical subtrochanteric and shaft 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 findings and radiographic evidence of stress fractures, weeks or months before the onset of stress fractures. a complete femoral fracture. 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 discontinuing bisphosphonate therapy pending an assessment of the patient based on the individual benefit-risk ratio.

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.

Skin reactions

Rare cases of severe skin reactions, including Stevens Johnson syndrome and toxic epidermal necrolysis, have been reported in post-marketing experience.

Missed dose

Patients should be advised that if they miss a dose of Bonasol 70 mg Oral Solution, they should take a single unit dose (100 ml) the morning after the day they realize they have forgotten. They should not take two doses on the same day but should resume taking a single unit dose per week, as originally scheduled on the chosen day.

Kidney damage

The use of alendronate is not recommended in patients with renal impairment with a GFR below 35 ml / min (see section 4.2).

Bone and mineral metabolism

Other causes of osteoporosis need to be considered besides estrogen deficiency and age.

Hypocalcaemia should be corrected prior to initiation of alendronate therapy (see section 4.3). Other disorders of mineral metabolism (such as vitamin D deficiency and hypoparathyroidism) should also be effectively treated. Patients with these clinical conditions should be monitored. serum calcium and symptoms of hypocalcaemia during weekly Bonasol treatment.

Due to the positive effects of alendronate on increasing bone mineralization, a decrease in serum calcium and phosphate levels may occur, especially in patients taking glucocorticoids in whom calcium absorption may be reduced. Usually, these reductions are modest and asymptomatic. However, there have been some rare reports of symptomatic hypocalcaemia, sometimes severe, which have occurred in individuals with predisposing conditions (such as hypoparathyroidism, vitamin D deficiency and calcium malabsorption). It is particularly important to ensure adequate calcium and vitamin D intake in patients on glucocorticoid therapy.


This medicinal product contains 0.15% by volume in ethanol (alcohol), i.e. up to 115 mg per dose, equivalent to 3 ml of beer or 1.3 ml of wine per dose. It is harmful to alcoholics. This must be kept in mind for high risk groups such as patients suffering from liver disease or epilepsy.

Bonasol 70 mg weekly oral solution contains the dye Sunset Yellow (E110), methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) which can cause allergic reactions.

04.5 Interactions with other medicinal products and other forms of interaction -

When taken at the same time, food and beverages (including mineral water), calcium supplements, antacids and other oral medications are likely to interfere with the absorption of alendronate. Therefore, patients should allow at least 30 minutes to elapse after taking taken alendronate before oral intake of any other medicinal product (see sections 4.2 and 5.2).

No other interactions with medicinal products of clinical importance are foreseeable. In clinical studies, some patients were treated with estrogen (intravaginally, transdermally or orally) while receiving alendronate. No undesirable effects attributable to the concomitant use of these medicines have been observed.

Since the use of NSAIDs is associated with gastrointestinal irritation, special care should be taken when these medicinal products are taken concomitantly with alendronate.

Although specific interaction studies have not been performed, alendronate has been used in clinical studies in combination with a wide range of commonly used medicinal products without giving rise to evidence of clinically relevant adverse effects.

04.6 Pregnancy and breastfeeding -


There are no or limited data from the use of alendronate in pregnant women. Animal studies have shown reproductive toxicity. Alendronate administered to pregnant rats caused dystocia associated with hypocalcaemia in the dams (see section 5.3).

Bonasol 70mg Weekly Oral Solution should not be used during pregnancy.

Feeding time

It is not known whether alendronate is excreted in human milk in humans. A risk to the newborn / infant cannot be excluded. Alendronate should not be used in breastfeeding women.


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 -

Alendronate has no or negligible influence on the ability to drive or use machines. However, some adverse reactions that have been reported with alendronate may affect the ability of some patients to drive and use machines. Individual reactions to Bonasol weekly oral solution may be different (see section 4.8).

04.8 Undesirable effects -

In a one-year study involving postmenopausal women with osteoporosis, the overall safety profiles of alendronate tablets given weekly (n = 519) and alendronate 10 mg / day (n = 370) were found to be similar.

In two three-year studies, with virtually identical scheme, performed in postmenopausal women (alendronate 10 mg: n = 196; placebo: n = 397), the general safety profiles for alendronate 10 mg / day and for placebo they were similar.

Mechanism of action

The active substance in Bonasol weekly oral solution, alendronate (in the form of alendronate trihydrate), is an anti-osteoclastic bisphosphonate that has no direct effect on bone formation. Preclinical studies have shown that alendronate is preferentially localized to sites of active resorption. The activity is inhibited, but recruitment and adhesion of osteoclasts are not altered. The bone tissue formed during treatment with alendronate is qualitatively normal.

Clinical efficacy and safety

Treatment of postmenopausal osteoporosis

Osteoporosis is defined as a BMD of the spine or hip that is 2.5 SD less than the mean value in a normal young population, or as a history of a previous fragility fracture, regardless of BMD.

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. After one year, mean increases in lumbar spine BMD from baseline were 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 in the 70 mg once weekly and 10 mg once daily groups, respectively. The two groups were also similar with regard to increases in DMO values ​​in other bone districts.

The effects of alendronate on bone mass and fracture incidence in postmenopausal women were studied 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, mean increases in bone mineral density (BMD) following administration of alendronate 10 mg / day compared with placebo at three years were 8.8%, 5.9% and 7.8%. % in the spine, femoral neck and trochanter, respectively. BMD of the whole organism also increased significantly. A 48% reduction (alendronate 3.2% vs placebo 6.2%) was observed in the number of patients treated with alendronate, with one or more vertebral fractures compared with to those who received placebo.

Over 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 as a whole.

The FIT consisted of two placebo-controlled studies using alendronate (5 mg per day for two years and 10 mg per day for an additional year or two):

• FIT 1: A three-year study of 2,027 patients who had at least one vertebral (compression) fracture at baseline. In this study, alendronate administered daily reduced the incidence of ≥ 1 new vertebral fracture by 47% (alendronate 7.9% vs. placebo 15.0%).In addition, a statistically significant reduction in the incidence of hip fractures was observed (1.1% vs. 2.2%, a reduction of 51%).

• FIT 2: A four-year study of 4,432 patients with low bone mass but no 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 studies, asymptomatic, mild and transient decreases in serum calcium and phosphate levels were reported in approximately 18% and 10% of patients receiving alendronate 10 mg / day, respectively, compared with approximately 12% and 3% of patients treated. with placebo. However, the incidences of serum calcium reductions up to

Pediatric population

Alendronate 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 in pediatric patients with osteogenesis imperfecta.

05.2 "Pharmacokinetic properties -


Compared to an intravenous reference dose, the mean oral bioavailability of alendronate in women was 0.64% for doses ranging from 5 to 70 mg administered after an overnight fast and two hours before a standardized breakfast. Likewise, bioavailability decreased to approximately 0.46% and 0.39% after administration of alendronate one "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.

Bioavailability was negligible when alendronate was administered with or within two hours of a standardized breakfast. Concomitant administration of alendronate and coffee or orange juice reduced its bioavailability by approximately 60%.

In healthy subjects, prednisone administered orally (20 mg 3 times daily for five days) did not produce clinically important changes in the oral bioavailability of alendronate (a mean increase of 20% to 44%).


Studies in rats have shown that after intravenous administration of 1 mg / kg, alendronate initially distributed into soft tissues, is rapidly redistributed to bone or excreted in the urine. In humans, the mean steady-state volume of distribution, exclusive to "bone, is at least 28 liters.

The plasma concentrations of the medicinal product, after administration of therapeutic oral doses, are too low to be detected analytically (plasma protein is approximately 78%.


In both humans and animals, there is no evidence that alendronate is metabolised.


After a single intravenous dose of [14C] -labelled alendronate, approximately 50% of the absorbed radioactivity was eliminated in the urine within 72 hours, and little or no radioactivity was found in the faeces. Following administration of a single 10 mg intravenous dose, the renal clearance of alendronate was 71 ml / min, and the systemic clearance did not exceed 200 ml / min. Plasma concentrations fell by more than 95% within six hours of intravenous administration. The terminal half-life in humans was estimated to be greater than 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 it is not expected in humans to interfere at this level with the elimination of other medicinal products.

Kidney damage

Preclinical studies show that the medicinal product which does not settle in bone is rapidly eliminated in the urine. In animals, after chronic administration of cumulative doses up to 35 mg / kg, there was no evidence of saturation of uptake by Although no clinical information is available, it is likely that, as in animals, elimination of alendronate via the kidney is likely to be reduced in patients with renal impairment. Therefore, slightly more bone accumulation of alendronate could be expected. at the bone level in patients with renal impairment (see section 4.2 "Posology and method of administration").

05.3 Preclinical safety data -

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 treatment with alendronate during pregnancy is associated with dystocia linked to hypocalcaemia in mothers during parturition. In studies, rats given the highest doses had a higher incidence of incomplete fetal ossification. The relevance of these observations to humans is unknown.
