R.Ph.s can facilitate switch to HFA inhalers
March 05, 2007
As part of the 1987 international Montreal Protocol treaty to reduce/eliminate substances depleting the ozone layer, CFC (chlorofluorocarbon) propellants in albuterol metered-dose inhalers (MDIs) are gradually being replaced by HFAs (hydrofluoro-alkanes). The transition need not be complete until Dec. 31, 2008, when albuterol CFC-MDIs must be discontinued as mandated by the Food & Drug Administration. But the change is well under way. As Patty Johnson, spokeswoman for GlaxoSmithKline, noted, "We [GSK] already transitioned to Ventolin HFA MDI in early 2006."
