“Compared with 2005, twice as many drug shortages were identified in 2008, and in 2010 almost 180 shortages of medically necessary drugs were identi fied by the FDA, triple the amount from 2005,” according to the report. “Sterile injectables comprise the most common type of shortage, with 74 percent of the shortages in 2010 involving such preparations, including many older off-patent formulations and critical products for use in the acute-care setting. The problem has continued to escalate with ASHP reporting more than 200 shortages as of September 15. The most prominent causes include manufacturing difficulties and regulatory compliance issues; corporate decisions leading to product discontinuation; consolidation of the pharmaceutical industry; and raw, bulk, or active pharmaceutical ingredient shortage.”
