Actos is prescribed to individuals with type 2 diabetes to help control their blood sugar levels. Unfortunately, Actos has also been found to cause bladder cancer. Worse yet, the manufacturer allegedly under-reported some of the serious adverse effects of Actos, effectively putting sales and profit ahead of patient safety.
Avastin, approved by the FDA in 2004, was marketed as the first commercially available angiogenesis inhibitor. Angiogenesis refers to the process of growing blood vessels from pre-existing vessels. So in the case of Avastin, this angiogenesis inhibitor was essentially prescribed to stop cancerous cells from spreading. It is given intravenously and often times in conjunction with chemotherapy drugs. It’s primary uses have been in combating colon, lung, ovarian, and breast cancer and has also been used to treat eye disease (i.e. age-related macular degeneration).
