Unveiling cyclodextrin conjugation as multidentate excipients: An exploratory journey across industries.

The discovery of branched molecules like dextrin by Schardinger in 1903 marked the inception of cyclodextrin (CD) utilization, catalyzing its journey from laboratory experimentation to widespread commercialization within the pharmaceutical industry. CD, a cyclic oligosaccharide containing glucopyranose units, acts as a versatile guest molecule, forming inclusion complexes (ICs) with various host molecules. Computational studies have become instrumental in elucidating the intricate interactions between β-CD and guest molecules, enabling the prediction of binding energy, forces, affinity, and complex stability.

Spray-dried chitosan oligosaccharide microparticles with polyvinyl alcohol-based dispersions for improved gefitinib solubility.

The aim of research is to enhance the solubility of crystalline gefitinib (GF), a poorly water-soluble drug, by developing drug delivery systems using chitosan oligosaccharide (COS) particle engineering. Fabrication utilizes ionic gelation followed by spray drying. The preliminary evaluations such as Uv-Vis, FTIR, DSC followed by advanced techniques like SEM and invitro drug release characteristics was performed along with solubility study.
