There have been several headlines about a shortage of classic chemotherapy drugs recently. How do these things happen? This post at Marginal Revolution is the best short overall look at the problem that I’ve seen so far:
Currently there are about 246 drugs that are in short supply, a record high. These shortages are not just a result of accident, error or unusual circumstance, the number of drugs in short supply has risen steadily since 2006. The shortages arise from a combination of systematic factors, among them the policies of the FDA. The FDA has inadvertently caused drugs long-used in the United States to be withdrawn from the market and its “Good Manufacturing Practice” rules have gummed up the drug production process and raised costs.
As Alex Tabarrok says there, one pebble, or a few, won’t dam up a stream. But if you keep throwing them in, something’s going to happen, and I think that we’ve reached that point here. . .
