CA3113948A1 — Non-injectable hydrogel formulations for smart release

USPTO Abstract

A non-injectable formulation or formulation for instillation, including self-assembling hydrogels formed of gelators such as the Food and Drug Administration's Generally Regarded as Safe (GRAS) compounds like ascorbyl palmitate, in the form of capsules, tablets, oral suspensions, enemas, and rectal or vaginal suppositories or inserts have been developed. In a preferred embodiment, the formulation contains anti-inflammatories, anti-infectives, or other therapeutic, prophylactic, or diagnostic agents that can be administered orally, especially when lower blood levels relative to tissue levels of agent are preferred. In the most preferred formulation, the composition contains tacrolimus-loaded ascorbyl palmitate gel microfibers containing nanostructures ("hydrogels").
