Abstract: Dry powder formulations for pulmonary and/or intranasal drug delivery, delivery systems, and methods of making and using thereof have been developed. The dry powder formulation contains particles containing a retinoid and/or a retinoid derivative, such as tamibarotene; and a ?-cyclodextrin and/or a ?-cyclodextrin derivative. The dry powder formulation allows for improved drug adsorption and bioavailability in vivo. The particles of the dry powder formulation have favorable aerodynamic properties for deposition and retention in the lower and/or upper respiratory tract(s). The dry powder formulation can be prepared using spray-drying or spray-freeze-drying. Inhalation, intratracheal administration, and/or intranasal administration of the dry powder formulation can deliver to a subject an effective amount of the retinoid and/or retinoid derivative to prevent, treat, or ameliorate symptom(s) associated with a respiratory viral infection in the subject.

Abstract: Provided are relating to pulmonary delivery of mRNA as inhaled dry powder formulation and compositions comprising the mRNA; also provided are methods of using and making the composition.

Abstract: The present invention is a herbal composition and method of preparing thereof. The herbal composition comprising extracts of Carthami Flos (CF), Dipsaci Radix (DR), Notoginseng Rhizoma (NR) and Rhei Rhizoma (RR). The present invention also relates to an oil-in-water or water-in-oil type nano-emulsion and method of preparing thereof. The nano-emulsion comprises an aqueous phase, an organic phase and a surfactant, wherein said aqueous phase comprises hydrophilic extract of herbal materials and said organic phase comprises hydrophobic extract of said herbal materials. The present invention also relates to a transdermal patch comprises said nano-emulsion. The herbal composition of the present invention is useful in treating traumatic injuries, in particular bone injuries. The present nano-emulsion and patch thereof can promote skin absorption of active ingredients in herb, thereby increasing the herb's bioavailability and efficacy in therapy.
