Drug firm Natco Pharma Tuesday said it has submitted an abbreviated new drug application (ANDA) with the US health regulator for the generic version of Bosentan 32 mg tablets for oral suspension.

The company has filed the ANDA with Para IV certification with the US Food and Drug Administration (USFDA), it added.

Tracleer is indicated for treatment of pulmonary arterial hypertension, it added. Shares of Natco Pharma Tuesday closed at Rs 546.95 per scrip on the BSE, up 2.63 per cent from its previous close.
