A study from the University of California, San Diego School of Medicine, published online by PLoS ONE, reports that muscle problems reported by patients taking statins were related to the strength or potency of the given cholesterol-lowering drugs. Adverse effects such as muscle pain and weakness, reported to the U.S. Food and Drug Administration (FDA) were related to a statin's potency, or the degree by which it typically lowers cholesterol at commonly prescribed doses.

Almost 30 years after discovery of a link between alcohol consumption and certain forms of cancer, scientists are reporting the first evidence from research on people explaining how the popular beverage may be carcinogenic. The results, which have special implications for hundreds of millions of people of Asian descent, were reported at the 244th National Meeting & Exposition of the American Chemical Society.

An inexpensive antifungal drug, thiabendazole, slows tumor growth and shows promise as a chemotherapy for cancer. Scientists in the College of Natural Sciences at The University of Texas at Austin made this discovery by exploiting the evolutionary relatedness of yeast, frogs, mice and humans.

Although some studies have suggested that use of lipid-lowering therapies may increase the risk of pancreatitis, an analysis that involved pooling of data from previous studies and included more than 150,000 participants found that statin therapy was associated with a reduction in the risk of pancreatitis in patients with normal or mildly elevated triglyceride levels, according to an article in the August 22/29 issue of JAMA.

Canada needs a national approach to managing its supply of pharmaceutical drugs, starting with a mandatory reporting system for drug shortages, argues an editorial in CMAJ (Canadian Medical Association Journal) and CPJ (Canadian Pharmacists Journal).

In a major breakthrough, an international team of scientists has proven that addiction to morphine and heroin can be blocked, while at the same time increasing pain relief. The team from the University of Adelaide and University of Colorado has discovered the key mechanism in the body's immune system that amplifies addiction to opioid drugs.

Researchers from the Perelman School of Medicine at the University of Pennsylvania found that patients taking thiazolidinedione (TZDs) drugs - which account for up to 20 percent of the drugs prescribed to diabetics in the United States - are two to three times more likely to develop bladder cancer than those who took a sulfonylurea drug, another common class of medications for diabetes.
