Some Indian pharmaceutical companies are facing increased regulatory scrutiny in developed markets and that's perking up the view on the sector.

Drug maker, Aurobindo Pharma (Q,N,C,F)* has received the tentative approval for Donepezil Hydrochloride Tablets 5 mg and 10 mg (ANDA 90-056) from the US Food & Drug Administration (USFDA).

US drug maker Teva Pharmaceuticals has voluntarily recalled Propofol Injectable -- a drug used in the treatment of anxiety -- following incidents of side effects on patients.

Watson Pharma, a leading specialty pharmaceutical company, confirmed that its subsidiary, Watson Laboratories, Inc-Florida (Watson), has filed an Abbreviated New Drug Application (ANDA) with the US Food and Drug Administration seeking approval to market its trospium chloride extended-release 60 mg capsules prior to the expiration of a patent owned by Supernus Pharmaceuticals, Inc.
