Exposure of rodents to aerosol particles or vapors
Measurement of chemicals deposited in the
respiratory tract and accumulation in blood of rodents
Gross and microscopic examinations of rodents
Disease induction in animal models (e.g. cancer)
1. Drug solubilization through engineering solid form
(nanocaging, solid dispersion, cocrystallization, salt
formation, etc.)
2. Tablet formulation and manufacturing process
understanding and control
3. Structure-mechanical property relationship in
organic crystals and powders
C.C. Sun
The aqueous solubility of poorly soluble drugs is significantly improved by
nanocaging.
