Chitosan is a biopolymer derived from chitin, a natural polymer found in the shells of crustaceans such as shrimp, crabs, and lobsters. It is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitosan has a range of applications due to its unique physical and chemical properties, including its ability to form films, gels, and beads, and its biocompatibility.

Febuxostat solubilization and stabilization approach using solid dispersion method: Synergistic…
Drug solubilization studies are continuously being conducted. Febuxostat (FBX) has a low solubility in water. This study aims to develop a stable FBX-solid dispersion (SD) formulation using a solvent evaporation method. The solubilization strategy of FBX is to develope an optimal FBX-SD formulation…

Aptamer-modified chitosan-capped Mesoporous silica nanoparticles for co-delivery of cytarabine and…
Abstract
In this study, surface modified mesoporous silica nanoparticles (MSNs) were prepared for the targeted delivery of the anticancer agents, daunorubicin (DNR) and cytarabine (CTR), against K562 leukemia cancer cell lines. The MSNs were surface-modified with pH-sensitive chitosan (CS) to…

Bacteriophage entrapped chitosan microgel for biofilm-mediated poly bacterial infection in burn…
Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) bacteria are most commonly present in burn wound infections. Multidrug resistance (MDR) and biofilm formation make it difficult to treat these infections. Bacteriophages (BPs) are proven as an effective therapy against MDR…

Enhanced Anti-Herpetic Activity of Valacyclovir Loaded in Sulfobutyl-ether-β-cyclodextrin-decorated…
Valacyclovir (VACV) was developed as a prodrug of the most common anti-herpetic drug Acyclovir (ACV), aiming to enhance its bioavailability. Nevertheless, prolonged VACV oral treatment may lead to the development of important side effects. Nanotechnology-based formulations for vaginal administration…

Chitosan in Oral Drug Delivery Formulations: A Review
Abstract
Nanoformulations have become increasingly useful as drug delivery technologies in recent decades. As therapeutics, oral administration is the most common delivery method, although it is not always the most effective route because of challenges with swallowing, gastrointestinal discomfort,…
