Redispersible nanoparticulate film matrices with protective overcoats

摘要

A pharmaceutical film matrix comprising nanoparticles of a low solubility drug associated with a steric stabilizer and a film dispersing agent is coated on the surface of carrier particles and overcoated with a protective layer. Pharmaceutical compositions comprising the film matrix-coated carrier exhibit excellent bioavailability, are useful in methods of treating mammals and are extremely stable in that they are capable of being redispersed without extensive agglomeration into larger particles after being stored.
