Pharmaceutical companies have broken their social contracts with patients by pricing drugs too high, says Dr. Kenneth Davis, President and CEO of Mt. Sinai Health System. Dr. Davis says in the past, drugs for polio, penicillin and tuberculosis were priced so that everyone could afford the treatment. He says companies have lost their social consciousness over drug pricing, and now, Washington is talking about imposing regulatory controls. Davis says there needs to be equity across all countries in what consumers pay for drugs, so that the U.S. isn't paying a higher burden for research and development costs. He thinks the U.S. should discuss pharmaceutical pricing as part of trade deals.
