India-based Ranbaxy Laboratories announced on 5 September 2011 that it had successfully launched esomeprazole magnesium 20 mg and 40 mg tablets in the UK.

The French daily newspaper, Les Echos, reported on 1 September 2011 that sanofi France (sanofi) had reached an agreement with Pfizer to produce generic versions of the blockbuster cholesterol drug Lipitor (atorvastatin).

Pfizer is poised for a Lipitor (atorvastatin) reprieve in Europe. The company has asked for six months of additional exclusivity in most EU countries under regulations designed to promote drug trials for children. The extension could be worth almost US$800 million as it staves off generic competition until May 2012.

US pharma giant Pfizer announced on 2 June 2011 that it had signed a memorandum of understanding (MOU) with Chinese generics manufacturer Zhejiang Hisun Pharmaceuticals (Hisun) on their intention to establish a joint venture. This potential partnership would aim to strengthen the ability of both companies to reach more patients with high-quality and low-cost medicines in the branded generics arena.

Drug shortages in the US are at a record high and there appears to be no quick solution to the problem. Legislation, government stock-piling and physicians importing or even manufacturing drugs are just some of the solutions being proposed.

On 2 May 2011 a federal judge dismissed Mylan’s attempt to block rival generic company Ranbaxy Laboratories from launching a generic version of Pfizer’s blockbuster cholesterol-lowering drug Lipitor (atorvastatin) and trying to terminate Ranbaxy’s rights to sell generic atorvastatin in the US on an exclusive basis for six months.

Cholesterol fighter Lipitor (atorvastatin calcium) has been the worlds ‘best-selling drug’ for the last 10 years, and has been a major source of income for the world’s biggest drug company, Pfizer. Lipitor was released in 1998, and by 2006 it had reached peak sales of US$12.9 billion, accounting for 27% of the company’s revenue. In 2010, with US$10.8 billion in sales, Lipitor still accounted for 15.8% of total revenue, even with the addition of Wyeth’s operations.

Teva Pharmaceutical Industries (Teva) has not given up the fight to keep generics competition away from its blockbuster drug, Copaxone (glatiramer acetate). The company announced on 29 August 2011 that a US federal court had rejected interpretation claims from its challengers in patent infringement lawsuits over its proprietary multiple sclerosis treatment, setting a trial date of 7 September 2011.

According to Credit Suisse analysts, Ranbaxy Laboratories (Ranbaxy) may sell its rights to make a generic version of Pfizer’s cholesterol blockbuster Lipitor (atorvastatin), should it look unlikely to gain FDA approval in time for the planned November 2011 launch.

A landmark ruling from the US Supreme Court has decided that generic drug manufacturers do not have to change their drug’s safety label, even if stronger safety warnings are found to be required [1- 2]. This is the opposite of a ruling in 2009 that decided that patients could sue the manufacturer of a brand-name drug if its safety label is found to be inadequate, e.g. when new drug-related risks are discovered after the drug has made it to market [3, 4].
