  • Publication number: 20090018053
    Abstract: The present invention is concerned with a pharmaceutical formulation comprising an amylin agonist and optionally a buffer, a tonicifier or stabilizer, and a preservative in a container, for example, a vial, prefilled cartridge, prefilled syringe or disposable pen. This formulation may be in liquid, gel, solid or powdered form for delivery, for example, via nasal, pulmonary, oral, sublingual, buccal, transdermal, or parenteral routes. Formulation with biocompatible polymers and release modifiers, such as sugars, can facilitate controlled release after injection, minimizing the number of administrations to a patient. These formulations maintain stability upon storage under refrigerated or room temperature conditions. Such formulations can be further combined with insulin for administration to a patient.

  • Patent number: 5573783
    Abstract: 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.
