Drug-delivery vehicles based on reversed liquid crystalline phase materials

摘要

Uncoated particles of reversed cubic phase or reversed hexagonal phase material containing an active disposed within are provided. The uncoated particles have an ionic charge that is sufficient to stabilize them in dispersion in a liquid, e.g. a polar solvent. The active that is disposed within the particles may be, for example, a pharmaceutical or nutriceutical compound. The invention also contemplates drug formulations containing reversed hexagonal and reversed cubic phases that can be applied to significantly increase the duration of action of the drug and/or provide the same duration and efficiency at a significantly lower dose.
