Popis: In this work we describe the development and characterization of a new formulation of insulin (INS). Insulin was complexed with cyclodextrins (CD) in order to improve its solubility and stability being available as a dry powder, after encapsulation into poly (D,L-lactic-co-glycolic acid) (PLGA) microspheres. The complex INS : CD was encapsulated into microspheres in order to obtain particles with an average diameter between 2 and 6 microm. This system was able to induce significant reduction of the plasma glucose level in two rodent models, normal mice and diabetic rats, after intratracheal administration.
