Our laboratory focuses on research and development of patient friendly emerging formulations, drug delivery systems (DDS) and novel manufacturing processes from the viewpoint of particle design engineering. We have established non-invasive administration route such as orally and pulmonary administration using DDS nanocarriers for peptide drugs which are generally injected to patients. Nanoparticle technologies such as liposomes that deliver drugs to the retina by topical instillation are developed to avoid intraocular injection for posterior ocular diseases. We are also working on intracellular DDS of nucleic acid drugs such as siRNA and developing non-invasive formulations such as oral, pulmonary and eye drop administrations.
Drug nanocrystal formulations and emerging formulation such as polymeric nanofiber are also developed to improve the solubility of poorly water-soluble drugs. We are also interested in orally disintegrating (OD) tablets and OD films.
In the field of pharmaceutical manufacturing, we are developing an integrated continuous manufacturing system that can efficiently produce pharmaceutical formulations using spherical crystallization, continuous formulation (powder) processes, and novel pharmaceutical manufacturing equipment.
