On page 1480, Annalisa Dalmoro, Alexander Y. Sitenkov, Gaetano Lamberti, Anna Angela Barba, and Rouslan I. Moustafine discuss an enteric shell‐core microparticle encapsulating indomethacin produced by a solvent‐free method based on ultrasonic atomization and a two‐stage polyelectrolyte complexation. In particular, a water solution of the anionic biopolymer alginate containing indomethacin was sprayed first in fine droplets complexed with the cationic (meth)acrylate copolymer Eudragit ® E 100, and then with the anionic copolymer Eudragit ® L30D‐55. The first complexation stage was applied to achieve a high drug encapsulation efficiency; the second one to assure gastroresistance. (DOI: 10.1002/app.42976 )
