Solubility Enhancement

As the number of new drug candidates that are poorly soluble in water grows, new technologies that enable the enhancement of their solubility are needed. This is the case with amorphous solid dispersions (ASDs) that, nowadays, not only ensure the solubility, but can also be used to control the …

Cyclodextrins (CDs) are a family of cyclic oligosaccharides, consisting of a macrocyclic ring of glucose subunits linked by α-1,4 glycosidic bonds. The shape of CD molecules is similar to a truncated cone with a hydrophobic inner cavity and a hydrophilic surface, which allows the formation of…

Biotherapeutic development presents a myriad of challenges in relation to delivery, in particular for protein therapeutics. Protein delivery is complicated due to hydrophilicity, size, rate of degradation in vivo, low permeation through biological barriers, pH and temperature sensitivity, as well as…
