Sustainability arithmetic turns against unit-dose ampoules
Unit-dose ampoules carried preservative-free conversion for a decade by sealing a single dose, but a patient uses far less than an ampoule holds and roughly 68% of the product is discarded, while the format consumes around nine times the plastic per dose that a multi-dose system requires. Packaging waste requirements now reaching pharmaceuticals make that difficult to defend. Commercially this reverses a decade of format growth and redirects it toward multi-dose preservative-free systems at 12.6%, which is an unusually sharp change of direction for a regulated packaging category. Payers are already applying the arithmetic in formulary decisions.
