Tentative approval for more new Sun Pharma generics

Genéricos/General | Posted 20/10/2010 0 Post your comment

Sun Pharma is not slowing down with the number of new generic medication introductions. The latest generics to come out of the company include versions of riluzole hydrochloride and rosuvastatin.

On 28 September 2010, Sun Pharma announced that it had received tentative approval from the FDA for its Abbreviated New Drug Application (ANDA) for a generic version of sanofi-aventis’s Rilutek tablets 50 mg.

The generic riluzole hydrochloride tablets are indicated in the treatment of amyotrophic lateral sclerosis. Rilutek has annual sales of approximately US$50 million in the US.

Then on 29 September 2010, the company announced that it had received tentative approval from the FDA for its ANDA for a generic version of Astra Zeneca’s blockbuster cholesterol treatment Crestor.

The generic rosuvastatin calcium tablets are indicated for treatment of hypertriglyceridemia (high cholesterol) and approval covers 5 mg, 10 mg, 20 mg and 40 mg tablet forms of the medication. This is a big one for Sun Pharma, as Crestor has annual sales of approximately US$3.4 billion in the US.

These tentative approvals, however, mean that the generics cannot yet be marketed in the US because of existing patents and/or exclusivity rights.

Patents supporting Crestor, one of Astra Zeneca's biggest money-spinners, began expiring in 2006. However, so far, Astra Zeneca has managed to block companies marketing generic versions and has won court battles upholding its patent protection until 2016.
