For millions of people worldwide, this means switching from familiar brands like Lipitor to generic equivalents. How will this affect drug companies, and what will be the impact on people who depend on expensive prescription medication? Here, a brief guide: Which drugs are scheduled to go generic? Some real blockbusters. "In the next two years, six of the 10 top-selling drugs will lose their patents," says Chris Woolston in the Los Angeles Times. Lipitor, the world's best-selling drug, which is used to lower cholesterol, will be available as a generic in November of this year. Another best-seller, the blood thinner Plavix, will lose its patent in May 2012. Other well-known drugs with expiring patents include the arthritis treatment Enbrel, the anti-psychotic Zyprexa, as well as drugs for bipolar disorder, HIV, high cholesterol, and other conditions.
