using controlled drug delivery devices is one of the novel methods of drug delivery which is used to perform drug therapy with the minimum side effects. mucoadhesive polymers are one of these devices. chitosan is a natural polymer which is a suitable candidate for this purpose due to it is biocompatibility, bioadhesion and high capability to adsorb peptide drugs. since gi tract has both acidic ...

The aim of this study was to develop and characterize chitosan microspheres Carvedilol (CRV) for nasal delivery improve bioavailability treatment hypertension angina pectoris. comes under BCS class II, is poorly water soluble drug highly permeable. Solubility determined by shaking flask method lipophilicity separating funnel method. route very convenient achieving high reduce hepatic first pass...

objective (s): mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease.materials and methods:everydiscs containing 70 mg stem bark extract of ziziphus jujuba were formulated  by using carbopol 934, pvp k30 and gelatin as polymers. discs were made by granulation  and direct compression. discs were standardized based on the total phenol.  properties such as in vi...

mucoadhesive polymers that bind to the gastric mucin or epithelial cell surface are useful in drug delivery for the purpose of increasing the intimacy and duration of contact of drug with the absorbing membrane. several synthetic polymers are in use for this purpose. since the biodegradability of the synthetic polymers are questionable, in this investigation, an oral mucoadhesive controlled del...

Curcumin (Cur) is a striking anticancer agent, but its low aqueous solubility, poor absorption, hasty metabolism, and elimination limit its oral bioavailability and consequently hinder its development as a drug. To redress these limitations, amphiphilic chitosan (CS) conjugate with improved mucoadhesion and solubility over a wider pH range was developed by modification with hydrophobic acryloni...

Magnetically-actuated soft robots for medical applications are required to be functional, biocompatible, as well capable of robust motion inside human organs. In this paper, a ring-shaped magnetic robot, with flexible biopolymeric film coating, on mucus-coated surfaces is designed and investigated. The made from chitosan–glycerol (C–G) solution endows the robot locomotion capabilities diverse g...

Aim: The aim of the work was to explore mucoadhesive properties Mastic gum by involving it in microspheres with Amoxicillin Trihydrate as a model drug. Using Carbopol-934P and varying amounts gum. Methods: 9 interpretations were made using Design expert software. A central composite design applied test impact independent variables (Carbopol-934P mastic levels) on drug released at 10h strength r...
