Lifelong anticoagulation is necessary for the prevention of stroke in patients with rhythm disturbances and with mechanical valves. Patients who have a coronary stent implanted also need the antiplatelet drugs aspirin and clopidogrel to prevent the rare but lethal complication of stent thrombosis.

The first trial to study patients with acute coronary syndrome who do not undergo coronary stenting or bypass surgery found no significant difference between two anti-clotting drugs - prasugrel and clopidogrel - in preventing the first occurrence of death, heart attack or stroke, according to Duke University Medical Center cardiologists.

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.

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.
