Drugresins
Drugresins are a class of pharmaceutical materials consisting of drug-binding resins, typically polymeric resins, used to form drug-resin complexes that can modulate release and mask taste. They can be natural, semi-synthetic, or synthetic polymers bearing charged groups that allow binding of drug molecules.
The binding usually occurs through ionic interactions on ion-exchange resins or other interactions on hydrophobic or
Preparation involves mixing the drug with resin under controlled pH to maximize binding and then filtering,
Applications include oral sustained or targeted release formulations and taste masking, particularly for bitter or unpalatable
