Zydus Cadila has received final approval from US Food and Drug Administration (FDA) to market macitentan tablets, 10 mg.
Macitentan is used to manage the symptoms of pulmonary arterial hypertension.
Macitentan is in a class of medications called endothelin receptor antagonists. It works by stopping the action of endothelin, a natural substance that causes blood vessels to narrow and prevents normal blood flow in people who have pulmonary arterial hypertension.
According to the US FDA letter, Zydus was one of the first ANDA applicants to submit a substantially complete ANDA with a paragraph IV certification for macitentan tablets, 10 mg. Therefore, with this approval, Zydus is eligible for 180 days of shared generic drug exclusivity for macitentan tablets, 10 mg.
The group now has 314 approvals and has so far filed over 400 ANDAs since the commencement of the filing process in FY 2003-04.
