Effects of Weak and Strong Cation Exchange Resins on Moisture Uptake Behavior of Ranitidine Hydrochloride
The aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable H+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. Drug resin complexes (DRC) were prepared and evaluated for the percentage of moisture gain when placed in a humidity c...
متن کاملDisplacement chromatography on synthetic ion-exchange resins. 1. Separation of organic bases and amino-acids using cation-exchange resins.
9. Accumulation of glutamate also occurred in isolated kidney cortex, spleen, lung and chorion. Six other tissues examined maintained a concentration gradient between tissue and medium, but did not increase the glutamate concentration above the original level. 10. It is pointed out that tissue slices afford a system in which problems of permeability and storage can be studied under controlled c...
متن کاملCopper(II) Removal using Three Cation Exchange Resins: Ion Exchange Equilibrium and Kinetics
The removal of copper from aqueous solution by Amberjet 1500H, Amberjet 1300H and Amberlite IRC86 ion exchange resins is described. The Amberjet 1500H shows a remarkable increase in sorption capacity for copper compared to other adsorbents. The adsorption process shows maximum removal of copper in pure aqueous solution for an initial copper concentration of 5.98 mmol/L. The metal ions adsorptio...
متن کاملIon Exchange Resins and Applications in Pharmaceutical Technology
Ion exchange resins (IER) are cross-linked, water insoluble polymers carrying ionizable functional groups on their repeating positions. They are considered as safe materials due to their insoluble and nonabsorbable nature. This advantage made IER subject of several research in different areas of pharmaceutical technology such as oral sustained release, taste masking, rapid dissolution, stabilit...
متن کامل[Ion exchange resins].
Ion exchange resins have been used to help formulate pharmaceuticals since the late 1950's. During that time they have proved to be safe and effective excipients and are now used in many commercial formulations throughout the world. In this article we will look at some of the common problems faced by formulators and how using ion exchange resins may be able to solve them. Ion exchange resins ar...
