Chitosan is one of the most used polysaccharides in the design of drug delivery strategies
for administration of either biomacromolecules or low molecular weight drugs. For these …

… were maintained at 160 ± 2 C (when mannitol was used as excipient) and 135 ± 2 C (for
lactose), resulting in outlet temperatures of 108 ± 3 C and 85 ± 3 C, respectively. The airflow …

Over the last few decades, polysaccharides have gained increasing attention in the biomedical
and drug delivery fields. Among them, glucomannan (GM), has become a particularly …

This work presents a new dry powder system consisting of microencapsulated protein-loaded
chitosan nanoparticles (CS NPs). The developed system was evaluated in vivo in rats in …

Among the different approaches to achieve colon-selective drug delivery, the use of polymers,
specifically biodegraded by colonic bacteria, holds great promise. In this work a new …

This paper describes the preparation of new buccal bilayered devices comprising a drug-containing
mucoadhesive layer and a drug-free backing layer, by two different methods. …

The administration of drugs through the pulmonary route offers great advantages, but it also
requires overcoming many challenges. There is a need to develop appropriate carriers to …

Chitosan/tripolyphosphate nanoparticles have already been demonstrated to promote peptide
absorption through several mucosal surfaces. We have recently developed a new drug …
