The osteoporosis drug zoledronic acid (Zometa) seems to shrink breast tumors in patients who undergo chemotherapy, according to research presented at the San Antonio Breast Cancer Symposium.
In a study of 205 women undergoing chemotherapy, those who received Zometa in addition to chemotherapy were left with residual invasive tumors of 28.2 millimeters, while those receiving chemotherapy alone had residual tumors sized at 42.4 millimeters. Eleven percent of the women receiving combination therapy had no evidence of cancer in their breasts or lymph nodes compared with six percent of those who received chemotherapy alone.
Zometa is already approved as a treatment for breast cancer that has spread to the bone, and reportedly may lower the recurrence of breast cancer in pre-menopausal women with estrogen- or progesterone-positive tumors.
The study’s senior author, Dr. Robert Coleman of the University of Sheffield in England, expects that new trials will be designed to further test the hypothesis.
Zometa, like Fosamax,is a bisphosphonate and—also like Fosamax—has been linked to side-effects such as spontaneous osteonecrosis of the jaw, or “dead jaw.”
Medications can have unexpected benefits as well as negative side-effects. Have you experienced any such benefits while taking Fosamax? Please share your experiences with us.

Is Alkalinity the Key to Preventing Osteoporosis?
Side effects from popular osteoporosis drugs do not outweigh the benefits says Dr. Susan Lark, a women’s health practitioner and specialist in preventative medicine. Lark believes that all bisphosphonates like Fosamax and Reclast should be avoided because they can cause gastrointestinal side effects, chemical burning of the esophagus, infection and death of bone tissue in the jaw (called osteonecrosis), kidney toxicity, and atrial fibrillation.
The major problem she sees with bisphosphonates is that they don’t increase bone growth, but instead prevent the current bone from being reabsorbed back into the body. Normally bones are in a continuous state of recycling new bone in for the old bone. Drugs like Fosamax and Reclast halt this process, preventing further bone loss, but at the same time preventing bone growth. According to Lark, there are much safer, natural ways to prevent bone loss.
Dr. Lark believes the secret to preventing osteoporosis is maintaining alkalinity. Blood is typically alkaline with a PH of 7.35 to 7.45. Part of the way the body maintains this PH level is by releasing bone minerals like calcium, magnesium, potassium, and sodium into the blood. However as people get older, their PH-regulating system declines in efficiency causing their blood to become more acidic. Over the years, things like an acidic diet, stress, and pollutants all contribute to an acidic blood PH. Eventually body is required to break down more bone minerals to keep a healthy PH level, putting older people at a higher risk for osteoporosis.
To stay alkaline, Dr. Lark suggests four steps. First, cut out acidic foods like red meat, dairy products, alcohol, carbonated soft drinks, caffeine, refined sugar, and most artificial sweeteners. Also cut down consumption of acidic fruits, including citrus, apples, most berries, plums, apricots, pineapple, and raisins. Second, Eat more alkaline foods like green vegetables, whole grains, legumes, seafood, eggs, and non-acidic fruits. Third, build up extra mineral reserves by taking mineral supplements like calcium, magnesium oxide, zinc, silica, boron, and vitamins C, D, and K. Finally, you can increase the buffering capacity (alkalinity) of your water by adding sodium bicarbonate (baking soda).

FDA Claims No Association between Fosamax and Atrial Fibrillation
The FDA recently released a statement saying that there is no connection between the drug Fosamax, used to treat osteoporosis, and an increased risk of atrial fibrillation. The FDA reviewed information for 19,687 patients who had taken a bisphosphonate like Fosamax and 18,358 patients who had taken a placebo. Each patient was monitored between 6 months to 3 years. They found that atrial fibrillation was rare (2 or fewer events per study) and that there was no clear link connecting these events to bisphosphonate drugs.
This FDA statement came after recent reports at the 74th annual American College of Chest Physicians conference suggesting that there is a connection between bisphosphonates and an irregular heart beat that can cause fainting, fatigue, heart failure, or stroke.
A study involving 16,000 patients at the University of Miami showed that patients taking Fosamax or Zometa (another popular bisphosphonate) could have a 68% increased risk of serious atrial fibrillation causing hospitalization or death. Yet, the total number of patients experiencing an irregular heart beat was small at 2.5 to 3.5 percent.
Another recent study published by the New England Journal of Medicine in May 2007 also suggested that bisphosphonates can increase the risk of this heart problem. Compared to the FDA data of 6 months to 3 years, this study lasted 5 years, ending in 1997. The results found that the risk for a serious irregular heart beat could be 50% higher in patients taking Fosamax compared to the placebo group.
With these conflicting reports it seems hard to know what to believe. One alternative is RateADrug.com where you can get a non-biased report of individual’s experiences with Fosamax. Please add to this growing database of community reported information and review Fosamax.

Fosamax May Permanently Stop New Bone Growth
Our bones are constantly being broken down and rebuilt throughout our lives in a process called bone remodeling. As adults, this can include up to 10% of our entire skeletal mass at any one time. This process gives our bones the ability to grow and also heal after injuries. When there is an imbalance between how much bone is reabsorbed and how much new bone is made, Osteoporosis occurs.
Recent reports are showing that osteoporosis patients who take bisphosphonates like Fosamax may be unable to grow new bone, even if they stop taking the drug. This was shown in a study where bisphosphonates reduced the effectiveness of parathyroid hormone (PTH) treatment, a technique used to stimulate new bone growth in osteoporosis patients.
Bisphosphonates like Fosamax work by preventing the breakdown of current bone mass. As Fosamax is absorbed into the bones it inhibits osteoclast cells, which are responsible for breaking down old bone. Because the destruction and creation of bone mass are closely related, Fosamax also prevents new bone from forming by stopping osteoclast cells from signaling the osteoblast cells responsible for bone building.
The effects Fosamax has on a patient’s bones are somewhat irreversible as it remains deposited in bones for years due to its very long half-life. Even if a patient stops taking Fosamax, it will be years before it is completely out of the patient’s system. Thus, the necessary bone growth needed for advanced stage osteoporosis patients may not be possible if they have taken bisphosphonates.

Fosamax Sales Dive 50% Since Generic Form Was Approved
Merck, maker of osteoporosis drug Fosamax, announced its plans to cut 7,200 more jobs as profits fall from declining sales in its top drug lines. Fosamax, one of Merck’s blockbuster drugs, dropped more than 50% in sales since its patent expired on February 6, 2008. Fosamax has been one of the top 100 most frequently dispensed drugs in the U.S.
The FDA approved Teva Pharmaceuticals USA to produce the first generic form of Fosamax, alendronate sodium tablets. Generic forms of prescription drugs are becoming more widely accepted. 63 percent of prescriptions were filled by generic drugs in 2006 – up from 56% in 2005. According to Gary J. Buehler, R.Ph, director of the FDA's Office of Generic Drugs, "The FDA works to assure the safety and efficacy of generic drugs through a rigorous scientific and regulatory process."
As Merck is showing declining sales, Medicare has announced that it is saving $6 billion in prescription drug costs by shifting to generic forms of drugs like Fosamax. This is down 12% from $50 billion.
In addition to Fosamax declines, Merck’s cholesterol lowering drugs Vytorin and Zetia dropped 15% while Gardasil sales, their vaccine to prevent cervical cancer, dropped 4%.
Merck said that it is looking to change its business model for the future. They want to rely less on large sales pushes and consolidate research on particular diseases in single locations. Additionally, they are planning to focus more on biotechnology drugs made from living cells. These types of drugs are more difficult to replicate than chemical drugs and thus have more profit potential as generic forms are less likely undercut their market.

Fosamax Makers Face Lawsuits for Osteonecrosis of the Jaw Side Effect
Over 650 lawsuits have been filed by women throughout the United States who have developed osteonecrosis of the jaw after taking bisphosphonates like Fosamax to treat osteoporosis. Osteonecrosis of the jaw is an irreversible bone disease causing the jaw bone to become brittle, die, and sometimes requires partial jaw removal. The first of three court case is planned for August 11, 2009.
Fosamax (alendronic acid), produced by Merck Co., is a bisphosphonate drug used by millions of women to treat osteoporosis as well as Paget’s Disease and other fragile bone conditions. It works by inhibiting osteoclast cells which naturally break down bone and release minerals back into the body. However, in the process, it also effects new bone growth. In order for new bone to be made, osteoclast cells must signal their counterpart, osteoblast cells, which are responsible for building new bone. Thus, new bone growth is inhibited as osteoclast cells absorb Fosamax. As this happens, fewer small blood cells are able to grow and less blood is able to reach bone cells. Eventually this may cause the bone to become brittle and die.
Patients are claiming that Merck has known about this side effect for over five years, but has not provided adequate warning about the risk of osteonecrosis. Over the past few years there has been an increase in the number of jaw osteonecrosis cases noted by dentists. Additionally, there have also been reports of osteonecrosis of the hip, shoulder, and knee.
Osteonecrosis symptoms typically don’t appear until it is too late to reverse the effects. Symptoms may include jaw pain, swelling, infection of the gums, loose teeth, or exposed jaw bone within the mouth. Fosamax patients should avoid any minor dental surgery that may expose the jaw bone like having a tooth pulled. This may prompt infection and prevent healing.

Fosamax May Cause Chronic Irregular Heartbeat
A new study by the University of Washington, published in the Archives of Internal Medicine, found that Fosamax may double your risk of developing chronic atrial fibrillation. Atrial fibrillation is an abnormal heart rhythm resulting in a decreased amount of blood to the body. This can cause dizziness, fainting, fatigue, chest pain, or congestive heart failure. Furthermore, it increases the likeliness of blood clots and possible stroke.
The long-term study looked at 719 women patients who had been diagnosed with atrial fibrillation. Of them, 6.5 percent had taken Fosamax in the past for their osteoporosis. This was significantly higher than the 4.1 percent of women who had taken Fosamax but had not developed an irregular heartbeat. Thus, women who had taken Fosamax were 86 percent more likely to have atrial fibrillation compared to those who had not. Furthermore, the study showed that Fosamax is the sole cause of 3 percent of all cases of this condition.
Case in point, one 67 year old woman found herself in the emergency room for atrial fibrillation after taking Fosamax for seven years to treat mild osteoporosis. She was a nonsmoker, nondrinker and led a healthy lifestyle with exercise and good nutrition. Additionally, there was no history of heart disease in her family.
This study wasn’t the first to find that osteoporosis treating drugs can cause heartbeat abnormalities. A study in 1997 of zoledronate, known by the brand names Aclasta, Reclast, Zomera and Zometa, found this drug to significantly increase the likeliness of developing chronic atrial fibrillation compared to the placebo.

Fosamax Side Effects
Osteoporosis, meaning porous bones, is a disease where the body does not generate new bone minerals as quickly as they are dissolved back into the body. Bones become weak and brittle and the risk of fracture from common day activities increases.
Fosamax is the major pharmaceutical drug used to treat osteoporosis. Fosamax is a bisphosphonate that works by combining with bone tissue to increase and maintain bone density thereby preventing further breakdown of bone minerals.
This is useful in treating osteoporosis, however, as part of its function, Fosamax is difficult for the body to eliminate and can remain in the system for up to ten years after discontinuing treatment.
Fosamax targets all bones in the body whether it is desired or not. Because not all bones are structurally the same throughout, this can cause problems. One adverse effect of this is osteonecrosis of the jaw where there is a loss of blood supplied to the jaw bone. This can cause the jaw bone to “die” making it brittle and ultimately causing it to collapse and need to be surgically removed. Jaw bone death is typically experienced in cancer patients who have been receiving intravenous bisphosphonates (vs. pill form) to treat cancer that has spread to the bones. Bisphosphonates, like Fosamax, prevent small blood vessels from growing, which helps starve and kill cancer cells. Unfortunately, this may also starve bone cells in the process. Patients who undergo dental surgery such as a tooth extraction may also be at a higher risk due to bone exposure during the procedure.
Furthermore, a recent article published in the New England Journal of Medicine (NEJM) stated that, in very rare circumstances, bisphosphonates may cause inflammatory eye disease. Only four cases have been reported, and in all cases they were successfully treated with corticosteroids.
Additional adverse effects may include flu symptoms, irregular heartbeat, or a severe rash. The FDA also recently issued a warning that Fosamax may cause severe bone, joint, and muscle pain.
