Abstract: A pharmaceutical composition generally includes a primary microparticle having at least one drug dispersed within a matrix and a taste masking seal coating dispersed over at least a portion of the primary microparticle. In some embodiments, the seal coating can include a reverse enteric coating. In other embodiments, the seal coating can include a water-soluble polymer such as carrageenan, hypromellose, or polyvinyl alcohol. In some embodiments, the seal coating is continuous. In other embodiments, the seal coating is discontinuous. The pharmaceutical composition can be prepared using a two-step spray drying process.

Abstract: The present invention is directed to protocells for specific targeting of hepatocellular and other cancer cells which comprise a nanoporous silica core with a supported lipid bilayer; at least one agent which facilitates cancer cell death (such as a traditional small molecule, a macromolecular cargo (e.g.

Abstract: The invention provides novel antibiotic protocells comprising mesoporous nanoparticles encapsulated within a lipid bi- or multilayer. The nanoparticles have pore sizes and surface chemistries that enable facile adsorption and intracellular presentation of antibiotics which are effective in the treatment of a wide variety of bacterial infections, including F. tularensis, B. pseudomallei and P. aeruginosa-related infections. Related pharmaceutical compositions and methods of treatment are also provided.
