Characterization of the flow and compression properties of chitosan
(North-West University, 2008)The most useful dosage form taken from a patient's point of view is tablets because of its simplicity and portability (Takeuchi et al., 2004:132). Manufacturing of tablets can be done by wet granulation or direct compression ... -
A comparison on the release modifying behaviour of chitosan and kollidon SR
(North-West University, 2007)Controlled release formulations deliver an active ingredient over an extended period of time. It is an ideal dosage form for an active ingredient with a short elimination half-life. An active ingredient with a short ... -
Development of a double phase dosage form for enhanced peptide drug delivery
(2015)Parenteral administration remains the most utilised route of administration for therapeutic peptides due to low intestinal epithelial permeability. However, the most convenient and popular route of drug administration ... -
The effect of pharmaceutical excipients on isoniazid release from chitosan beads
(North-West University, 2007)In controlled release applications a drug is molecularly dispersed in a polymer phase. In the presence of a thermodynamically compatible solvent, swelling occurs and the polymer releases its content to the surrounding ... -
The effect of pharmaceutical excipients on rifampicin release from chitosan beads
(North-West University, 2004)Controlled release systems aim at achieving a predictable and reproducible drug release over a desired time period. These systems allow reduced dosing frequency, constant drug levels in the blood, increased patient compliance ... -
The effect of pharmaceutical excipients on the release of indomethacin from chitosan beads
(North-West University, 2006)Chitosan has proven through the years as a versatile biomaterial to be used in pharmaceutical applications. Its mucoadhesive properties as well as its ability to manipulate the tight junctions in epithelium membranes have ... -
Formulation of a chitosan multi-unit dosage form for drug delivery to the colon
(North-West University, 2006)In some diseases it is preferable that the drugs used in their treatment are released in the colon. The colon is also suitable for systemic delivery of a variety of drugs. A variety of systems have been developed for the ... -
Formulation, characterisation and topical application of oil powders from whey protein stabilised emulsions
(2014)The available literature indicates that to date, few research has been performed on oil powders for topical delivery. The aim of this project was to investigate the release characteristics of oil powder formulations, as ... -
In vitro evaluation of the cytotoxic, antibacterial and antioxidant properties of selected chitosan derivatives and melittin
(North-West University (South Africa) , Potchefstroom Campus, 2015)New excipients to improve the oral absorption of drugs are developing significantly. Polymers are used to enhance drug absorption through the gastrointestinal tract. Chitosan is a biocompatible polymer that is capable of ... -
Influence of modified release excipients on ketoprofen release from chitosan particles
(North-West University, 2005)Controlled release formulations offer many advantages over conventional dosage forms. These include reduced plasma fluctuations and improved patient comp1i:nce. Complex controlled release formulations such as those with ...
