title: First inhaled insulin product approved.
abstract: There is a new, potential alternative for many of the more than 5 million Americans who take insulin injections, with the Food and Drug Administration's approval of the first-ever inhaled insulin. Exubera, an inhaled powder form of recombinant human insulin (rDNA) for the treatment of adult patients with type 1 and type 2 diabetes, is the first new insulin delivery option introduced since the discovery of insulin in the 1920s.
