Teva UK, a part of Teva Pharmaceutical Industries, has introduced the generic atorvastatin film-coated tablets in 10mg, 20mg, 40mg and 80mg strengths in the UK.
The generic version of Pfizer's Lipitor is indicated for the treatment of hypercholesterolaemia and to prevent cardiovascular disease.
The company is launching the product in Teva 360 livery, in packs of 28.
Teva commercial director Kim Innes said the company has launched atorvastatin in the UK on the day its patent expires.
"Millions of prescriptions are written each year in the UK for atorvastatin, and the availability of the generic will save the NHS millions of pounds each year," Innes added.
"It and other patent expiries provide pharmacy the opportunities for increasing margins and keeping costs down, and also mean we at Teva continue to do our bit in saving the NHS over £9bn a year through the availability of generic medicines."
