Opt-e-scrip, Inc., has developed a patented test for determining the efficacy of drugs in individual patients so that doctors can prescribe the drug that really works for each person. In addition, test results show that older, less expensive drugs are often as or more efficacious than the newer, expensive drugs pushed by manufacturers. It, thus, benefits physicians, patients, and drug benefit payers. However, the company has had difficulty entering the market, given its complexity and their lack of resources. The test remains a product in search of an application and a customer willing to pay for its usage.
