The system has the potential for use in a oral mucoadhesive drug delivery systems: a review where the subscripts t,g and b represent tissue, where t is the time of contact and db is the diffusion coefficient of. Presently, nanoparticle based drug delivery system are playing an essential role in the pharmaceutical industry a new drug delivery system of an existing drug can provide a new marketability which is the important in the economic point of view the next generation nanoparticles based insulin may be.

Hyaluronic acid, and chitosan) polysaccharide-based microparticles have gained much attention in developing controlled-release microparticulate systems because of their flexibility in obtaining a desirable drug release profile, cost-effectiveness. Chitosan-alginate microparticulate delivery system for an alternative route of administration of bcg vaccine in 3rd portuguese bioengineering meeting, university of minho (gualtar campus), 20th-22nd february, 2013 p 69-71. Polymeric controlled delivery systems based on chitosan are now being used for a wide range of drugs (4-6) chitosan as a non-viral vehicle for transferring dna molecules into the cells has recently attracted much attention because of its unique properties (7, 8.

Recently, a novel “nano and microparticulate” chitosan based system (nmcs) has been developed using a double emulsion like technique and evaluated for drug and gene delivery in specific regions of the gastrointestinal tract 10,11 spray-drying has been used to increase drug solubility and bioavailability of active substances, modified. Chitosan, a natural based-polymer obtained by alkaline deacetylation of chitin, is nontoxic, biocompatible, and biodegradable these properties make chitosan a good candidate for the development of conventional and novel drug delivery systems. Thus, systems 2–5 can be arranged in the order of increasing intensity of the band characteristic for oh groups: system 3 system 4 system 2 system 5, which suggests an increase of the intensity of interactions between the components of the systems.

Chitosan based microparticulate systems

The unique biological properties of a chitosan-based hydrogel enable it to serve as both a wound dressing and as a drug delivery system (dds) to deliver antibacterial agents, growth factors, stem cells and so on, which could further accelerate wound healing. Microparticulate drug delivery system is one of the microsphere-based formulations can be formulated to provide a constant drug concentration in collagen chitosan dextrin, gelatin, hyaluronic acid, dextran, fibrinogen, alginic acid ,casein, fibrin, poly(ortho esters. Abstract: microparticulate drug delivery systems provides numerous advantages like, increased surface area, modified release pattern, improved bioavailability etc in the present work, attempt has been made to use chitosan, natural. Based on the fecal fat increase and dietary intakes, the fat-binding capacity of the chitosan used was 18 g/g chitosan in another study, investigators found that the apparent fat digestibility in a group of 8 to 10 rats was ∼23% ( 22 .

  • Based on this finding, further testing is intended on chitosan-oregano films destined for a system with prolonged active substance release figure 3: antimicrobial activity of chitosan films with the oregano eo at days 3 and 8 against gram-positive bacteria (a) staphylococcus aureus and (b) bacillus cereus.
