An ultrafast-acting insulin aspart formulation for mealtimes (Fiasp), for adult patients with type 1 or 2 DM, was approved in January 2017 for use in Canada and the Europe Union. The drug contains conventional mealtime insulin aspart in combination with two ingredients—vitamin B3 and the amino acid L-arginine—that are meant to allow faster insulin absorption so the medication can better mimic natural physiologic insulin. Unlike in the European Union, however, the new formulation is not approved for insulin pumps in Canada. The product has not yet been approved for use in the United States. [149]
