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.

Antipsychotics-Loaded Nanometric Emulsions for Brain Delivery
Antipsychotic drugs have numerous disabling side effects, and many are lipophilic, making them hard to formulate at high strength. Incorporating them into nanometric emulsions can increase their solubility, protect them from degradation, and increase their brain delivery, being a promising strategy…

On a highway to the brain: A review on nose-to-brain drug delivery using nanoparticles
The administration of drugs to the central nervous system (CNS) is primarily controlled by the blood-brain barrier (BBB), a structure that prevents the passage of foreign compounds from the blood to the brain's extracellular fluid. Although currently available treatments for brain diseases that…

Orally Administered Amphotericin B Nanoformulations: Physical Properties of Nanoparticle Carriers on…
Amphotericin B is an effective polyene antifungal considered as a “gold standard” in the management of fungal infections. Currently, it is administered mainly by IV due to poor aqueous solubility, which precludes its delivery orally. Paradoxically, IV administration is akin to side effects that have…
