Summary

Cellulose Esters for Sustained Release
- CA-398-10 NF/EP, CA-320S NF/EP, CAB-171-15 NF
- Semipermeable, strong, flexible film formers for coatings
- Coating properties modifiable through blending CAs or CA with CAB
- Directly compressible, matrix for sustained release tablets
- CAB more hydrophobic than CA
- Applications: osmotic drug delivery, extended-release tablets, taste masking, sustained release binders
- Formulation tips: solvent required, additives for varied film properties, blend CA with CAB for sustained release

Enteric Coating Polymer - C-A-P NF
- pH-sensitive, hydrolyzes at pH 6 or higher
- Solvent-based, stable in sealed, cool, dry containers
- Two physical forms: powder, pellet; compressible
- Multiple plasticizers suitable
- Advantage: coats small tablets, water-sensitive actives
- Applications: enteric coating, delayed release binders
- Formulation tips: solvent systems, plasticizers for flexibility, ammonia neutralization for aqueous systems, low usage levels (0.5%)
