Bisphosphonates are a class of drugs that prevent the loss of bone density, used to treat osteoporosis and similar diseases. They are the most commonly prescribed drugs used to treat osteoporosis. [1] They are called bisphosphonates because they have two phosphonate (PO(OH)
2) groups. They are thus also called diphosphonates ( bis- or di- + phosphonate ).

Contents

Evidence shows that they reduce the risk of fracture in post-menopausal women with osteoporosis. [2] [3] [4] [5] [6]

Bone tissue undergoes constant remodeling and is kept in balance (homeostasis) by osteoblasts creating bone and osteoclasts destroying bone. Bisphosphonates inhibit the digestion of bone by encouraging osteoclasts to undergo apoptosis, or cell death, thereby slowing bone loss. [7]

The uses of bisphosphonates include the prevention and treatment of osteoporosis, Paget's disease of bone, bone metastasis (with or without hypercalcemia), multiple myeloma, primary hyperparathyroidism, osteogenesis imperfecta, fibrous dysplasia, and other conditions that exhibit bone fragility.

Medical uses

Bisphosphonates are used to treat osteoporosis, osteitis deformans (Paget's disease of the bone), bone metastasis (with or without hypercalcemia), multiple myeloma, and other conditions involving fragile, breakable bone.

In osteoporosis and Paget's, the most popular first-line bisphosphonate drugs are alendronate and risedronate. If these are ineffective or if the person develops digestive tract problems, intravenous pamidronate may be used. Strontium ranelate or teriparatide are used for refractory disease. The use of strontium ranelate is restricted because of increased risk of venous thromboembolism, pulmonary embolism and serious cardiovascular disorders, including myocardial infarction. [8] In postmenopausal women, the selective estrogen receptor modulator raloxifene is occasionally administered instead of bisphosphonates. Bisphosphonates are beneficial in reducing the risk of vertebral fracture in steroid induced osteoporosis. [9]

Post-menopausal osteoporosis

Bisphosphonates are recommended as a first line treatments for post-menopausal osteoporosis. [5] [10] [11] [12]

Long-term treatment with bisphosphonates produces anti-fracture and bone mineral density effects that persist for 3–5 years after an initial 3–5 years of treatment. [2] The bisphosphonate alendronate reduces the risk of hip, vertebral, and wrist fractures by 35-39%; zoledronate reduces the risk of hip fractures by 38% and of vertebral fractures by 62%. [3] [4] Risedronate has also been shown to reduce the risk of hip fractures. [5] [6]

After five years of medications by mouth or three years of intravenous medication among those at low risk, bisphosphonate treatment can be stopped. [13] In those at higher risk ten years of medication by mouth or six years of intravenous treatment may be used. [13]

Cancer

Bisphosphonates reduce the risk of fracture and bone pain [14] in people with breast, [15] lung, [16] and other metastatic cancers as well as in people with multiple myeloma. [17] In breast cancer there is mixed evidence regarding whether bisphosphonates improve survival. [15] [18] [19] [20] A 2017 Cochrane review found that for people with early breast cancer, bisphosphonate treatment may reduce the risk of the cancer spreading to the person's bone, however, for people who had advanced breast cancer bisphosphonate treatment did not appear to reduce the risk of the cancer spreading to the bone. [15] Side effects associated with bisphosphonate treatment for people with breast cancer are mild and rare. [15]

Bisphosphonates can also reduce mortality in those with multiple myeloma and prostate cancer. [20]

Other

Evidence suggests that the use of bisphosphonates would be useful in the treatment of complex regional pain syndrome, a neuro-immune problem with high MPQ scores, low treatment efficacy and symptoms which can include regional osteoporosis. In 2009 bisphosphonates were "among the only class of medications that has survived placebo-controlled studies showing statistically significant improvement (in CRPS) with therapy." [21]

Bisphosphonates have been used to reduce fracture rates in children with the disease osteogenesis imperfecta [22] and to treat otosclerosis [23] by minimizing bone loss.

Other bisphosphonates, including medronate (R1=H, R2=H) and oxidronate (R1=H, R2=OH), are mixed with radioactive technetium and injected, as a way to image bone and detect bone disease.

Adverse effects

Common

Oral bisphosphonates can cause upset stomach and inflammation and erosions of the esophagus, which is the main problem of oral N-containing[ further explanation needed ] preparations, that is ones containing "normal" unbranched chains. This can be prevented by remaining seated upright for 30 to 60 minutes after taking the medication. Intravenous bisphosphonates can give fever and flu-like symptoms after the first infusion, which is thought to occur because of their potential to activate human γδ T cells.

Bisphosphonates, when administered intravenously for the treatment of cancer, have been associated with osteonecrosis of the jaw (ONJ), with the mandible twice as frequently affected as the maxilla and most cases occurring following high-dose intravenous administration used for some cancer patients. Some 60% of cases are preceded by a dental surgical procedure (that involves the bone), and it has been suggested that bisphosphonate treatment should be postponed until after any dental work to eliminate potential sites of infection (the use of antibiotics may otherwise be indicated prior to any surgery). [24]

A number of cases of severe bone, joint, or musculoskeletal pain have been reported, prompting labeling changes. [25]

Some studies have identified bisphosphonate use as a risk factor for atrial fibrillation (AF), though meta-analysis of them finds conflicting reports. As of 2008, the US Food and Drug Administration did not recommend any alteration in prescribing of bisphosphonates based on AF concerns. [26] More recent meta-analyses have found strong correlations between bisphosphonate use and development of AF, especially when administered intravenously, [27] but that a significantly increased risk of AF that required hospitalization did not have an attendant increased risk of stroke or cardiovascular mortality. [28]

Long-term risks

In large studies, women taking bisphosphonates for osteoporosis have had unusual fractures ("bisphosphonate fractures") in the femur (thigh bone) in the shaft (diaphysis or sub-trochanteric region) of the bone, rather than at the femoral neck, which is the most common site of fracture. However, these fractures are rare (12 in 14,195 women) compared to the common hip fractures (272 in 14,195 women), and the overall reduction in hip fractures caused by bisphosphonate is more than the increase in unusual shaft fractures. [29] [ obsolete source ] There are concerns that long-term bisphosphonate use can result in over-suppression of bone turnover. It is hypothesized that micro-cracks in the bone are unable to heal and eventually unite and propagate, resulting in atypical fractures. Such fractures tend to heal poorly and often require some form of bone stimulation, for example bone grafting as a secondary procedure. This complication is not common, and the benefit of overall fracture reduction still holds. [29] [30] [ non-primary source needed ] In cases where there is concern of such fractures occurring, teriparatide is potentially a good alternative because it does not cause as much damage as a bisphosphonate does by suppressing bone turnover. [31]

Three meta analyses have evaluated whether bisphosphonate use is associated with an increased risk of esophageal cancer. Two studies concluded that there was no evidence of increased risk. [32] [33] [34]

Chemistry and classes

All bisphosphonate drugs share a common phosphorus-carbon-phosphorus "backbone":

The two PO
3 (phosphonate) groups covalently linked to carbon determine both the name "bisphosphonate" and the function of the drugs. Bis refers to the fact that there are two such groups in the molecule.

The long side-chain (R2 in the diagram) determines the chemical properties, the mode of action and the strength of bisphosphonate drugs. The short side-chain (R1), often called the 'hook', mainly influences chemical properties and pharmacokinetics.

See nitrogenous and non-nitrogenous sections in Mechanism of action below.

Pharmacokinetics

Of the bisphosphonate that is resorbed (from oral preparation) or infused (for intravenous drugs), about 50% is excreted unchanged by the kidney. The remainder has a very high affinity for bone tissue, and is rapidly adsorbed onto the bone surface. Once bisphosphonates are in bone, they have a very long elimination half-life that can exceed ten years. [35]

Mechanism of action

Bisphosphonates are structurally similar to pyrophosphate, but with a central carbon that can have up to two substituents (R1 and R2) instead of an oxygen atom. Because a bisphosphonate group mimics the structure of pyrophosphate, it can inhibit activation of enzymes that utilize pyrophosphate.

The specificity of bisphosphonate-based drugs comes from the two phosphonate groups (and possibly a hydroxyl at R1) that work together to coordinate calcium ions. Bisphosphonate molecules preferentially bind to calcium ions. The largest store of calcium in the human body is in bones, so bisphosphonates accumulate to a high concentration only in bones.

Bisphosphonates, when attached to bone tissue, are released by osteoclasts, the bone cells that break down bone tissue. Bisphosphonate molecules then attach to and enter osteoclasts where they disrupt intracellular enzymatic functions needed for bone resorption. [36]

There are two classes of bisphosphonate compounds: non-nitrogenous (no nitrogen in R2) and nitrogenous (R2 contains nitrogen). The two types of bisphosphonates work differently in killing osteoclasts.

Non-nitrogenous

The non-nitrogenous bisphosphonates (diphosphonates) are metabolised in the cell to compounds that replace the terminal pyrophosphate moiety of ATP, forming a non-functional molecule that competes with adenosine triphosphate (ATP) in the cellular energy metabolism. The osteoclast initiates apoptosis and dies, leading to an overall decrease in the breakdown of bone. This type of bisphosphonate has overall more negative effects than the nitrogen containing group, and is prescribed far less often. [37]

Nitrogenous

Nitrogenous bisphosphonates act on bone metabolism by binding and blocking the enzyme farnesyl diphosphate synthase (FPPS) in the HMG-CoA reductase pathway (also known as the mevalonate pathway). [38]

Bisphosphonates that contain isoprene chains at the R1 or R2 position can impart specificity for inhibition of GGPS1. [39]

HMG-CoA reductase pathway HMG-CoA reductase pathway.svg
HMG-CoA reductase pathway

Disruption of the HMG CoA-reductase pathway at the level of FPPS prevents the formation of two metabolites (farnesol and geranylgeraniol) that are essential for connecting some small proteins to the cell membrane. This phenomenon is known as prenylation, and is important for proper sub-cellular protein trafficking (see " lipid-anchored protein " for the principles of this phenomenon). [40]

While inhibition of protein prenylation may affect many proteins found in an osteoclast, disruption to the lipid modification of Ras, Rho, Rac proteins has been speculated to underlie the effects of bisphosphonates. These proteins can affect both osteoclastogenesis, cell survival, and cytoskeletal dynamics. In particular, the cytoskeleton is vital for maintaining the "ruffled border" that is required for contact between a resorbing osteoclast and a bone surface.

Statins are another class of drugs that inhibit the HMG-CoA reductase pathway. Unlike bisphosphonates, statins do not bind to bone surfaces with high affinity, and thus are not specific for bone. Nevertheless, some studies have reported a decreased rate of fracture (an indicator of osteoporosis) and/or an increased bone mineral density in statin users. The overall efficacy of statins in the treatment of osteoporosis remains controversial. [41]

History

Bisphosphonates were developed in the 19th century but were first investigated in the 1960s for use in disorders of bone metabolism. Their non-medical use was to soften water in irrigation systems used in orange groves. The initial rationale for their use in humans was their potential in preventing the dissolution of hydroxylapatite, the principal bone mineral, thus arresting bone loss. In the 1990s their actual mechanism of action was demonstrated with the initial launch of alendronate by Merck & Co. [42]

Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to bone sterility, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. Bones that commonly break include the vertebrae in the spine, the bones of the forearm, the wrist, and the hip. Until a broken bone occurs there are typically no symptoms. Bones may weaken to such a degree that a break may occur with minor stress or spontaneously. After the broken bone heals, the person may have chronic pain and a decreased ability to carry out normal activities.

Senile osteoporosis has been recently recognized as a geriatric syndrome with a particular pathophysiology. There are different classification of osteoporosis: primary, in which bone loss is a result of aging and secondary, in which bone loss occurs from various clinical and lifestyle factors. Primary, or involuntary osteoporosis, can further be classified into Type I or Type II. Type I refers to postmenopausal osteoporosis and is caused by the deficiency of estrogen. While senile osteoporosis is categorized as an involuntary, Type II, and primary osteoporosis, which affects both men and women over the age of 70 years.

It is an anti-osteoporotic drug approved for the prevention and treatment of osteoporosis in post-menopausal women and men to reduce vertebral fractures, hyperparathyroidism, hypercalcemia in malignancy, multiple myeloma and fracture related pain because of its anti-inflammatory effects shown as a reduction in inflammatory markers like IL-1β, IL-6, and TNF-α.

Steroid-induced osteoporosis is osteoporosis arising from the use of glucocorticoids analogous to Cushing's syndrome but involving mainly the axial skeleton. The synthetic glucocorticoid prescription drug prednisone is a main candidate after prolonged intake. Bisphosphonates are beneficial in reducing the risk of vertebral fractures. Some professional guidelines recommend prophylactic calcium and vitamin D supplementation in patients who take the equivalent of more than 30 mg hydrocortisone, especially when this is in excess of three months. The use of thiazide diuretics, and gonadal hormone replacement has also been recommended, with the use of calcitonin, bisphosphonates, sodium fluoride or anabolic steroids also suggested in refractory cases. Alternate day use may not prevent this complication.

Bisphosphonates are an important class of drugs originally commercialised in the mid to late 20th century. They are used for the treatment of osteoporosis and other bone disorders that cause bone fragility and diseases where bone resorption is excessive. Osteoporosis is common in post-menopausal women and patients in corticosteroid treatment where biphosphonates have been proven a valuable treatment and also used successfully against Paget's disease, myeloma, bone metastases and hypercalcemia. Bisphosphonates reduce breakdown of bones by inhibiting osteoclasts, they have a long history of use and today there are a few different types of bisphosphonate drugs on the market around the world.
