Why are various drugs in short supply and our goverment does not have an agency to be proactive rather than reactive?

FDA. Good question. Fda is more strict in approving drug than other countries. Its a catch 22 , good because it allows time to observe for adverse effects that can occur once in the open market. Bad because it may increase cost to patients. Keep writing to your congressman and pharmaceutical. We stool have the health system and country in the world. Well continue to work for you.
