Actually there is something of a hidden crisis in the medical community pertaining to drug shortages. A lot of these drugs are critical, life saving drugs that were once ubiquitous. On another forum I go to, one of the contributors is a hospital physician and he talks about in detail, and apparently the FDA now operates a website clearing house giving the latest daily figures on what is in short supply and suggested alternatives. He says many of these alternatives are not as good, and patient care is absolutely affected as a result.
The ultimate cause is government regulations that have removed profit motivations from the manufacture of established, generic drugs. The pharmaceutical companies simply curtail or eliminate production of unprofitable lines, and the result has been shortages of basic medications that should never be a consideration in any First World hospital. I'll try to dig up some links about this situation and post them here.
