Alembic Pharmaceuticals has secured approval from the U.S. Food and Drug Administration (USFDA) for its Macitentan tablets, a key treatment for pulmonary arterial hypertension (PAH). This approval enables Alembic to market the drug in the highly regulated U.S. pharmaceutical market, marking a significant milestone in its international expansion strategy. Analysts note that entering the U.S. market not only diversifies revenue streams but also reinforces Alembic’s global credibility in specialty therapies.
