These studies are mainly addressed to DPI or dry powder inhalers.The focus is on the techniques for drug transformation in order to obtain aerodynamic powders of active substances, characterized by favorable metering, aerosolization and lung or nasal deposition.The technique of powder agglomeration is also studied in order to have meterable powders composed of microparticles.These agglomerates are defined chimeral due to their dimension that, being large after agglomeration, is in reality small, since the agglomerares are easy broken apart by water contact.Agglomerated powders are suitable for nasal, buccal or dermal administration.For more information: Prof. P.
