'These products are dangerously misleading because they are targeted to patients with serious conditions and limited treatment options,' stated Autor. Though freedom from autism is what every parent wants, FDA compliance expert Deborah Autor fears that the companies selling the drugs and tests are preying on people who are venerable and desperate for a cure. Chelation drugs are supposed to work by ridding the body of heavy metals and many companies also sell a test that they say can detect the presence of such metals in the body. One group of drugs are called chelation drugs. The makers claim that the drugs can treat not only autism but cardiovascular disease, macular degeneration and Parkinson's disease. Many parents are willing to go to great lengths to find answers to the puzzle that is autism. As there are no approved drugs to treat the condition some parents find themselves looking at alternative therapies and medicines.
