Gelation Factors of Pectin for Development of a Dry Jelly
06. November 2017
Jellies for oral administration are dosage forms that contain water, as stipulated in the Japanese Phar- macopeia, and heat is generally applied to the jellies during the manufacturing process. Therefore, it is difficult to formulate drugs that may be affected adversely by water and/or heat.

Abstract In this work, a bottom-up approach based on the study of polyelectrolyte interactions was performed in order to evaluate the effect of Prosopis alba exudate gum as novel excipient for fish oil encapsulation in composed calcium-alginate-chitosan beads. Emulsion and beads properties such as oil distribution, encapsulation efficiency, yield, microstructure and thermo-oxidative protection were evaluated. Alginate and gum exert a synergistic effect on emulsion stability properties, which...

Context: Sustained release drug delivery systems are more preferred than the conventional drug delivery systems due to its enhanced bioavailability and patient compliance. Earlier studies reported on glibenclamide (GBCM) were not clear and hence, the step has been taken to explore the sustained release drug delivery system of GBCM. Aims: To evaluate the sustained release microspheres obtained of GBCM. Methods: Microspheres were prepared by ionic gelation method using the polymers like Eudragit...

Abstract In situ -gelling systems has the great potential in the wide areas of drug delivery. The application areas of such systems are broad and these systems can be formulated not only as gels but also as in situ gelling nanospheres, microspheres and liposomes. To overcome the drawbacks associated with conventional drug delivery systems and take advantages of both solutions and gels, such as accurate dosing, ease of administration of the former and longer precorneal residence of the latter, a...

Abstract The purpose of this work was to develop a multiparticulate system exploiting the pH-sensitive prop- erty and biodegradability of calcium alginate beads for intestinal delivery of ceftriaxone sodium (CS). CS was entrapped in beads made of sodium alginate and sodium carboxymethylcellulose (CMC), acacia, HPMC K4M and HPMC K15M as drug release modifiers. Beads were pre- pared using calcium chloride as a cross-linking agent, followed by enteric coating with cellulose acetate phthalate...

Abstract: The main aim of the present work was to develop colon specific piroxicam loaded alginate microspheres intended for the treatment of rheumatoid arthritis. A multiparticulate system with a combined property of pH sensitive and biodegradability was developed. Piroxicam microspheres were prepared by using ionotropic gelation technique and coated by using coacervation phase separation method using different ratios of eudragit S100 which is a pH sensitive polymer. Both coated and uncoated...

Recently controlled and sustained drug delivery has become the new standard in modern pharmaceutical design and a thorough research has been undertaken in achieving much better drug product effectiveness, reliability and safety. In situ gelling system has become an outstanding among novel drug delivery system (NDDS) in recent years due to its advantages like sustained and prolonged drug action, improved patient compliance and reduced frequency of administration of the drug compared to...

Biopolymers such as tragacanth, an anionic polysaccharide gum, can be alternative polymeric carrier for physiologically important peptides and proteins. Characterisation of tragacanth is thus essential for providing a foundation for possible applications. Rheological studies colloidal solution of tragacanth at pH 3, 5 or 7 were carried out by means of steady shear and small amplitude oscillatory measurements. Tragacanth mucoadhesivity was also analysed using an applicable rheological method and...

We aimed to develop a suitable micropellet delivery system for Lansoprazole, a highly potent proton pump inhibitor and acid-unstable physiologically active anti-secretory compound. Although clinically manifested to be highly effective for treating acid reux-related diseases, poor water solubility and short gastric retention time, typically does not provide extended period of relief. Materials and method: Micropellets of the drug was prepared using ionotropic gelation technique, where gelation...
