Actos Bladder Cancer, Side Effect Study

According to the website EHealthMe, a study conducted on August 17, 2011 regarding the side effects of taking Actos and bladder cancer risk. According to the report, 22,512 reported side effects when taking Actos and 0.22% have bladder cancer. The largest concentration (approx. 43%) were using Actos between 2-5 years before having Bladder Cancer with the next largest concentration (approx. 29%) used Actos between 1-6 months.

Actos Side Effects, Bladder Cancer Risk

In June 2011, the Type 2 Diabetes drug Actos (piogliatazone) had its sales suspended by medical regulators in France and Germany because of a possible bladder cancer risk. The French and German decisions to ban the drug came after a study commissioned by the French Medicines Agency found that people taking Actos were more likely to develop bladder cancer, an aggressive form of cancer. The study examined cancer rates in some 155,000 people taking Actos in France from 2006 to 2009 and 1.3 million other diabetics who were not receiving the drug. The study found about a 22 percent higher risk of bladder cancer in those taking the drug compared with diabetics taking other drugs. The bladder cancer risk was highest in those receiving a cumulative dosage of 28,000 mg or more during the study period.

Also in June 2011, the U.S. Food & Drug Administration (FDA) announced it was reviewing Actos for a possible bladder cancer risk in September 2010. At the time the agency said early data from a 10-year study submitted by Takeda, the maker of Actos, had not indicated a statistically significant association between exposure to the drug and bladder cancer risk. However, there was some evidence that patients taking Actos at least two years or at the highest cumulative doses (>28,000 mg) did face a greater danger from bladder cancer.

In May 2011, another study, this time looking at Adverse Event reports to the FDA between 2004-2009, suggested that Actos patients faced a "disproportionate risk” of bladder cancer. The study looked at a half million side effect reports associated with various diabetes medications and found that a fifth of those involving bladder cancer occurred in patients using the drug.

New Research May Indicate Actos Cardiovascular, Heart Disease Side Effects and Risks

New research has added to the growing body of evidence linking Avandia and Actos to increased adverse health risks. Avandia has long been surrounded with debate concerning cardiovascular risks, while Actos was believed a safer alternative, causing sales of Actos to increase and Avandia sales seeing significant declines. The LA Times has stated that emerging research suggests that similar heart risks are being seen in both drugs, said the LA Times, which explained that both are part of the class called thizolidinediones. Thizolidinediones reduce body tissue insulin resistance and adjust cholesterol levels and are considered some of the strongest medications for treatment of Type 2 diabetes, noted the LA Times.

A 2007 study with over 200,000 Medicare patients pointed to Avandia's (generic: rosiglitazone) increased heart attack risks, cardiovascular disease, stroke, and death by 30-to-40 percent,” versus other, older diabetes medications, said the LA Times. That study indicated that the risk was not seen with Actos (generic: pioglitazone), added the LA Times.

The study prompted stronger U.S. Food and Drug Administration (FDA) label warnings, with even stronger warnings following more reports of increased risks with Avandia, said the LA Times; an FDA panel found the benefits of Avandia outweighed its risks and that it should remain on the market, but that no more patients be enrolled in a prospective study comparing the two drugs directly.

The team, led by Debra Wertz an outcomes research manager at HealthCore Inc., a Wellpoint Inc. research subsidiary—analyzed 28,938 patient records for people who took either medication from 2001 to 2005, obtaining company data, said the LA Times. Death information was derived from the National Death Index, which is managed by the National Center for Health Statistics. The research appears in the journal Circulation: Cardiovascular Quality and Outcomes.

When accounting age, gender, and prior heart disease, about four percent per group either suffered a heart attack or heart failure or died, said the LA Times. The figures break down to 96 Avandia, versus 121 Actos patients suffering a heart attack and 265 Avandia and 243 Actos patients suffering from heart failure, said the LA Times; 217 in each group died.

"What distinguishes this latest study from other claims-based analyses is its analysis of death records, which include out-of-hospital deaths," Wertz said in a statement, quoted the LA Times, and that the study followed younger patients longer than in prior studies. Earlier studies did not include stroke data, which could affect outcomes.

Another Study May Indicate Actos May Increase Risk Of Fractures

Parker Waichman had written previously that another study linked Avandia and Actos to an increased risk of fractures. The research appeared in the Journal of Clinical Endocrinology & Metabolism and found that the drugs increased the risk of fractures in postmenopausal women with Type 2 diabetes, as well as in men prescribed either drug with a loop diuretic.

Women over 50 who had broken bones were 71 percent likelier to have been prescribed a thiazolidinedione. In men, the increased risk (more than triple) was seen among those taking both a thiazolidinedione and loop diuretics, like Lasix, but not in just one or the other. The researchers pointed out that loop diuretics have been linked with bone density decreases. In both genders, the fracture risk went up the longer a person was on the medication. According to the researchers, the fractures seen in the study were not just the spine and hip fractures most often seen in people with osteoporosis. Many of the people included in the study suffered lower limb, arm, and leg fractures.

FDA Requires Actos To Have A Black Box Warning

After an intense debate over the safety of the Type-2 Diabetes drug Actos, the FDA has stated that the heart risk warnings on Actos (pioglitazone) will now be surrounded by an emphatic black outline known as a black box warning due to the serious risk of adverse cardiovascular events, including heart attack, heart failure, and cardiovascular-related deaths. A black box warning is the strongest FDA-requested label change that can be added to a drug.

Actos is a newer class of diabetes drugs called thiazolidinediones or glitazones, which increase the body's sensitivity to insulin. The FDA (Food and Drug Administration) approved Actos on July 15, 1999. Actos is manufactured by Takeda Chemical Industries.

The first approved drug in the class, Rezulin, was taken off the market in 2000 after it was linked to dozens of cases of fatal liver disease. Avandia is another drug that is a thiazolidinediones or glitazones.

The American Heart Association and American Diabetes Association issued recommendations to guide the use of Actos, a glucose-lowering drug and other drugs classified as thiazolidinediones (TZDs). Diabetics who have mild heart disease or any problems with their kidneys may be at an increased risk of developing congestive heart failure if they take certain diabetes medications, according to a new study.

The study, published in the September 9, 2003 issue of the Mayo Clinic Proceedings, reported on six cases of congestive heart failure in people taking pioglitazone (Actos) or rosiglitazone (Avandia) to help control their diabetes. The researchers studied the records of six men, between the ages of 66 and 78 years, with type 2 diabetes who had gone to the emergency room at Dallas Veterans Affairs Medical Center emergency room.

All six patients complained of shortness of breath, swelling of their feet, and weight gain, which are symptoms of congestive heart failure and pulmonary edema (fluid buildup in the lungs). Congestive heart failure occurs when the heart can no longer pump enough blood to maintain adequate circulation. Because the heart doesn't pump properly, fluid often builds up in the lungs.

Four of the six people in this study had chronic renal insufficiency, which means that their kidneys weren't functioning normally. Only two had any previous signs of heart disease. Four of the six had high blood pressure. They had been on the diabetes medications for between one month and 16 months. Three people developed symptoms within one to three months after the dose of their diabetes drug had been increased.
