19 Oct 2021 --- Astellas Pharma has begun using sugarcane-derived polyethylene as 50% of its raw material for creating pharmaceutical blister packs. The company says the move represents “the world’s first use” of biomass plastic for drug blister packs. Astellas will start using the biomass-based plastic blister pack for its “Irribow Tablet 5µg” tablets on the Japanese market, which target diarrhea-predominant irritable bowel syndrome.
