[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...
متن کاملSeparation and concentration of molybdenum(VI) and tungsten(VI) with chelating ion-exchange resins containing sulphur ligands.
Three chelating ion-exchange resins based on macroreticular polyacrylonitrile-divinylbenzene copolymers with thioglycollic acid and cysteine as functional groups have been tested for separation of molybdenum(VI) and tungsten(VI). On a short column of the thioglycollic acid resin, molybdenum(VI) and tungsten(VI) can be selectively sorbed from pH-4.3 acetate buffer and eluted with 2M hydrochloric...
متن کاملStudy of the Formulation Parameters Affecting the Preparation of Microencapsulated Ion-Exchange Resins Containing Venlafaxine Hydrochloride
Venlafaxine is a novel, non-tricyclic antidepressant. Venlafaxine imparts its antidepressant effects by inhibiting the neuronal uptake of norepinephrine, serotonin and to a lesser extent, dopamine1. It lacks monoamine oxidase activity and, more importantly, lacks the adverse effect profile of tricyclic antidepressants. Now, there has been the sustained-release preparation of this drug coming in...
متن کاملDevelopment of functional resins by modification of ion - exchange resins and their application to analytical chemistry
Some novel functional resins were developed for highly selective separation and/or determination of mercury, selenium, fluoride and hydrogen peroxide, by simple modification of common ion—exchange resin with appropriate reagents. These reagents should have three functional properties, namely selective reaction with the determinant of interest, an ion—exchange reaction with the resin and physica...
متن کاملDeodorizing experiments with ion exchange resins.
In a previous report (1), the differences in the carbon number of the lower fatty acids contained in cutaneous secretions such as axillary sweat, smegma, and dandruff, were considered as factors responsible for the difference in odor between osmidrotic and non-osmidrotic subjects. Besides these there are ammonia constituents and volatile salts (trimethylamine, methylamine) which may take part i...
