Preparation and Characterization of Theophylline-Chitosan Beads as an Aapproach to Colon Delivery

Chitosan with excellent biodegradable and biocompatible characteristics has received attention as an oral drug delivery vehicle for controlled-release formulations. In this study an enteric-coated capsule containing theophylline-chitosan beads based on 23 factorial designs was prepared as a colon drug delivery system. The theophylline-chitosan gel beads were formulated by adding the drug-contai...

Review: Chitosan Based Hydrogel Polymeric Beads – as Drug Delivery System

Chitosan obtained by alkaline deacetylation of chitin is a non-toxic, biocompatible, and biodegradable natural polymer. Chitosan-based hydrogel polymeric beads have been extensively studied as microor nano-particulate carriers in the pharmaceutical and medical fields, where they have shown promise for drug delivery as a result of their controlled and sustained release properties, as well as bio...

Preparation, characterization and stability investigation of chitosan nanoparticles loaded with the Echis carinatus snake venom as a novel delivery system

The chitosan nanoparticles used widely as a drug delivery systems recently. In the present study the Echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. The nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. The particles were spherical in shape and th...
