Major Companies Making Generic Lipitor
Lipitor (atorvastatin calcium) lost U.S. patent protection in 2011, enabling multiple generic manufacturers to produce and sell it. Ranbaxy Laboratories (now part of Sun Pharma) launched the first authorized generic in the U.S. that year after winning FDA approval and a patent settlement with Pfizer.[1] Other key players include Teva Pharmaceuticals, Mylan (now Viatris), Dr. Reddy's Laboratories, Lupin, and Watson Pharmaceuticals (now Teva), which secured FDA approvals for their versions between 2011 and 2016.[2]
Who Approves These Generics?
The FDA lists approved generic atorvastatin suppliers on its Orange Book database. As of recent checks, over 20 companies hold ANDAs (Abbreviated New Drug Applications) for various strengths (10mg to 80mg tablets), including Accord Healthcare, Aurobindo Pharma, Cipla, and Zydus Pharmaceuticals.[3] Approvals require bioequivalence to branded Lipitor, ensuring generics match in absorption and efficacy.
When Did Generic Entry Happen Globally?
U.S. generics entered November 2011 post-patent expiry (U.S. Patent No. 5,273,995 expired). In Europe, exclusivity ended in 2012, with companies like KRKA and Sandoz launching versions. Canada saw generics from Apotex and others by 2007, ahead of the U.S. due to different patent timelines.[4]
Are There Ongoing Patent Challenges?
Pfizer defended Lipitor patents aggressively, with Ranbaxy's first-to-file status granting 180-day exclusivity. Later challenges targeted extended-release formulations or combinations (e.g., Lipitor-Caduet), but core tablet patents expired without major post-2011 U.S. litigation.

How Do Generic Prices Compare to Branded Lipitor?
Generics slashed prices: U.S. retail for 30-day 20mg supply dropped from $150+ (branded) to under $10 by 2013. Today, prices hover at $1-5 monthly via chains like Walmart or GoodRx, varying by manufacturer—Teva and Mylan often undercut others.[6]
Common Patient Concerns with Generic Versions
Patients report no major differences in cholesterol-lowering effects, per FDA bioequivalence data. Rare complaints involve pill appearance or minor side effects (muscle pain, liver issues), identical to Lipitor's profile. Switching generics between manufacturers is safe if doses match.[7]
