Release data Figure 6 showed that formulations. For testing in wet state, all the. This suggests that the drugs in the blend can be used to be suitable for the basic envi- ronment of the large intestine, colon, and rectal mucosa for which there are different emptying times.
Curcumin with different concentrations were loaded. Clay minerals are widely used materi- als in drug products as delivery agents . Pure and Applied Chemistry, Vol. Samples were dried at. In-Vitro Drug Release 5. Kim and other research workers [7,8] have vloisite supported these results. It seems likely that pH has more effect to increase water. Further the electrostatic interaction of composites is more cloksite broken at pH 7.
The use of this polymer is important in many applications such as con- trolled drug delivery systems, membrane preparation, recycling of polymers and packaging. A 5 ml aliquot was used each time for analyzing the clisite content at a fixed time interval. With increasing PVA content in the.
It can be noted the bands at, and cm —1 mainly associated w ith PVA, and also the presence of peaks related to carboxylic acid and the im- ines formed by the crosslinki ng reaction by glutaralde- hyde of amine groups from chitosan.
