Features: cross-linked PVP is cross-linked polymer and a simultaneous controlled by insoluble material, and natural and semi-natural water soluble polymers crosslinked by the chemical composition of the majority of polymeric disintegrants different. The amorphous spherical particles by spray drying a free-flowing compressible powder with good dispersion and mobility. Because all of its cross-linked, so completely insoluble, no sticky, so do not delay the collapse or slow release, to ensure that after several wet / dry cycles can still play its full potential for collapse. Granulation process and tablet dissolution process does not generate gel, smooth operation, to ensure the disintegration performance.
Other uses: oral, injection, topical and ophthalmic liquid dosage forms, sustained release formulation, bio-adhesives, to improve the bioavailability of the solvent.
