That Seeking Alpha article seems to have another agenda, IMO.
I can't argue that NVS has threats looming to its pipeline. But, it seems preposterous to me to posit that an OTC drug from a tiny company poses a serious threat to NVS in general and Diovan in particular. This article seems more a way to promote "Chromadex Corporation's (CDXC.OB) patented pTeroPure® (pterostilbene)" than downplay the NVS pipeline with any credibility.
