Drug makers rush to produce new blood thinners

New blood-thinning medicines are in the works and to offer doctors more options in treatment and prevention of blood clots, according to Bloomberg. Bloomberg reports that at least six companies are working on blood thinners to take advantage of a growing need. According to Datamonitor, a London-based research company, the anticoagulation drug market is expected to reach $20 million by 2012.
Blood thinners are routinely given to patients before certain types of surgery and treatments such as kidney dialysis to prevent blood clots from forming. Clots that do not naturally dissolve can travel through the blood stream and end up in the brain, causing a stroke, or in the lungs, causing a pulmonary embolism. Blood clots, also known as thrombosis, is a serious problem affecting nearly a million Americans each year and killing nearly 300,000 annually.
Two more common types of blood thinners are heparin and warfarin. Heparin is administered intravenously, requiring medical supervision, whereas warfarin is given orally. Both drugs have been used medically for decades. Both have side effects that doctors and patients find bothersome, including easy bruising, excessive bleeding, lower back pain, weakness or light-headedness, and flu-like symptoms. Thus physicians are eager to find safer alternatives.
Furthermore, heparin has been in the spotlight continuously over the past several months for confusing labeling that has resulted from overdoses that have sickened and killed patients, as well as batches of contaminated heparin that made its way into hospitals, causing more illnesses and deaths in patients who received the bad lots.
