Ion Exchange Resins as Excipients for Drug Delivery: Issues for Reproducible Drug Loading
A method for repeatable loading of propranolol hydrochloride as a model drug onto the ion exchanger Amberlite TM IRP69 was developed and different parameters for the loading process were evaluated due to their impact of the extent of loading. It was found that the extent of loading in equilibrium is widely independent of the experimental method used. However, a magnetic stirrer comminutes the i...
متن کاملIon-exchange resins as drug delivery carriers.
There are many reports in the literature referring to the utilization of drug bound to ion-exchange resin (drug-resinate), especially in the drug delivery area. Ion-exchange resin complexes, which can be prepared from both acidic and basic drugs, have been widely studied and marketed. Salts of cationic and anionic exchange resins are insoluble complexes in which drug release results from exchan...
متن کاملDrug loading and release properties of ion-exchange resin complexes as a drug delivery matrix.
Complexes of ion-exchange resins and dextromethorphan (DM), a model drug, were prepared using different methods including a batch and a column method with different functional groups, ion-exchange capacity, degree of crosslinking, and resin particle size. Drug loading efficiency, release profiles, and scanning electron micrographs were also investigated. Most of the functional groups of resins ...
متن کاملIon-exchange, an Approach to Prepare an Oral Floating Drug Delivery System for Diclofenac
Using ion-exchange resins, a multiple-unit type of oral floating dosage system has been prepared to prolong gastric emptying time of dosage form. The system is composed of beads of drug-resin complex, which are loaded with bicarbonate ions and coated with a hydrophobic polymer. The system is so designed that when the beads reach the stomach, chloride ions are exchanged with bicarbonate and drug...
