Report: Authorized generic versions of Lipitor capture 14.6% of script volume
NEW YORK — Though they've been on the market for less than a month, the generic and authorized generic versions of Pfizer's cholesterol-lowering drug Lipitor have captured more than one-tenth of prescriptions, according to published reports.
Citing an analysis of data from IMS Health by J.P. Morgan, The Wall Street Journal reported that Ranbaxy's generic atorvastatin calcium tablets and Watson Pharmaceuticals' authorized generic have claimed about 14.6% of prescription volume since their launch on Nov. 30.
Ranbaxy and Watson respectively launched their generic and authorized generic versions of Lipitor the day Pfizer lost its patent protection for the drug, which IMS estimated to have sales of $7.8 billion during the latest moving-annual period. An authorized generic is a branded drug launched under its generic name at a reduced price, usually under a contract between the original branded drug's manufacturer and a third-party company.
