Consider, for example, FDA's 10-year delay, in 1967-76, in approving beta-blockers to prevent death following heart attacks, because of the agency's fear that the drugs might be carcinogenic. During those years, the drugs saved lives in Europe and elsewhere, while an estimated 10,000 heart attack victims unnecessarily died in this country each year. When beta blockers were finally approved in the US, to wide acclaim, hardly anyone raised the lethal effects of FDA's slowness.
