 | Oct 03, 2019 04:47AM ET

Shares of Bausch Health Companies Inc. (NYSE:BHC) are down 12.9% in the week so far. The company along with its wholly-owned subsidiary, Salix Pharmaceuticals, and Salix's licensor Alfasigma announced that they have filed a lawsuit against Sandoz Inc., the generics division of Novartis (NYSE:NVS) .

The lawsuit alleges infringement of 14 Xifaxan patents by Sandoz's filing of an Abbreviated New Drug Application (ANDA) for Xifaxan 550 mg.

Consequently, the stock declined. Per Bausch, Xifaxan is protected by 22 patents, covering the composition of matter and the use of Xifaxan listed in the U.S. Food and Drug Administration's (FDA) Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book.

The drug is approved for the treatment of irritable bowel syndrome with diarrhea (IBS-D) in adults. Bausch’s Salix business continues to drive growth and contribute to the top line. We note that Xifaxan is one of the key drugs for the company and increased sales of the drug are boosting sales. Revenues from the drug increased 16% in the first half of 2019 and contributed significantly to Salix’s revenues of $954 million.

Bausch’s stock has gained 2.3% in the year so far against a decline of 10% for the industry .
