The launch was followed by the approval by the US Food & Drug Administration (USFDA) of Dr Reddy's ANDA for atorvastatin calcium tablets, a company statement said here.
The Lipitor brand had US sales of approximately $8.07 billion for the most recent twelve months ending March 2012 according to IMS Health.
Dr Reddy's Atorvastatin calcium tablets are available in bottle count sizes of 90 and 500, the release said.
Last year DRL entered into a settlement agreement with Pfizer to resolve litigation over cholesterol lowering Lipitor tablets. New York-based Pfizer had sued Dr Reddy's in 2009.
