Abstract Nowadays, dry powder inhalation as applied in the therapy of pulmonary diseases is known as a very effective route of drug delivery to the lungs. Here, the system of coarse carrier and fine drug particles attached to the carrier surface has successfully been applied to overcome the cohesiveness of small drug particles. Particle properties of both carrier and drug are known to affect drug dispersion as has widely been discussed for lactose monohydrate and various drugs. This study...

In this study, we investigated the influence of deformability of specifically-engineered guest particles on the tensile strength of tablets of interactive mixtures. The binder polyvinylpyrrolidone (PVP) of different molecular weights were spray dried with l-leucine to create guest particle formulations. The guest particle formulations were characterized by their particle size, surface l-leucine concentration and glass transition temperature (Tg). These spray-dried particles were then blended...
