Drug firm Wockhardt Thursday said it has received zero observations from the US health regulator after inspection of its bioequivalence centre at Aurangabad in Maharashtra.

During the inspection, bioanalytical and quality systems of bioequivalence studies of Tamsulosin 0.4 mg capsules and Metoprolol ER tablets were audited, it added.

"At the end of inspection, there was nil observation (i.e. zero 483 observation), signifying that best practices were followed, in compliance to regulations," Wockhardt said.

This outcome would lead approvals of abbreviated new drug applications (ANDAs) in pipeline for which bioequivalence studies are being or will be done in the said centre, it added.

Shares of Wockhardt Ltd closed at Rs 383.15 per scrip on BSE, down 1.12 per cent.
