Abstract: A gel-forming free-flowing powder suitable for use as a vaccine is prepared by spray-drying an aqueous suspension that contains an antigen adsorbed to an aluminum salt adjuvant, a saccharide, an amino acid or a salt thereof, and a colloidal substance. Processes for forming these powder compositions are also described, as well as methods of using the compositions in a vaccination procedure.

Abstract: A process for producing a powder comprises spray freeze-drying an aqueous solution or suspension comprising a pharmaceutical agent, said solution or suspension having a solids content of 20% by weight or more. The spray freeze-dried powder may be administered to a subject via a needleless syringe.

Abstract: Hard, dense particles of a pharmaceutical agent, suitable for administration to a subject via a needleless syringe are described. The particles are prepared by a multi step process that entails forming particles of a first size where the particles are an admixture of a pharmaceutical agent and a macromolecular carrier and the admixture has a first glass transition temperature; admixing a plasticizer that lowers the first glass transition temperature of the admixture to a second glass transition temperature which is below the first glass transition temperature; maintaining the articles at a temperature above the second glass transition temperature for a time period adequate to cause the particles to shrink and/or collapse; removing the plasticizer from the particles to yield modified particles having an increased glass transition temperature; recovering the modified particles; and then storing the recovered particles.

Abstract: A gel-forming free-flowing powder suitable for use as a vaccine is prepared by spray-drying or spray freeze-drying an aqueous suspension that contains an antigen adsorbed to an aluminum salt or calcium salt adjuvant, a saccharide, an amino acid or a salt thereof, and a colloidal substance. Powder for vaccine purposes are also prepared by spray freeze-drying an aqueous suspension of such an adjuvant having an antigen adsorbed therein. Processes for forming these powder compositions are also described, as well as methods of using the compositions in a vaccination procedure.

Abstract: This invention relates to stable non-aqueous polar aprotic formulations of peptide compounds. These stable formulations comprise peptide in non-aqueous polar aprotic solvent. They may be stored at elevated temperatures for long periods of time and are especially useful in implantable delivery devices for long term delivery of drug.

Abstract: A sustained release delivery system for delivering a beneficial agent is provided. The system includes a reservoir comprising the beneficial agent and a capillary channel in communication with the reservoir and the exterior of the system for delivering the beneficial agent from the system. The capillary channel has a cross-sectional area and a length selected to deliver the beneficial agent at a predetermined rate. The system may further include an outer surface that is impermeable and non-porous during delivery of the beneficial agent. The beneficial agent may be formulated in a glassy sugar matrix.

Abstract: Dried proteins are stabilized against loss of biological activity in formulations by adding an reconstitution stabilizer upon rehydration of the dried protein. A kit for producing and a formulation produced by dissolving the dried composition in a solvent containing the reconstitution stabilizer is also described.
