Abstract: Formulations of an active pharmaceutical agent suitable for oral spray administration for absorption through the oral mucosa and related methods of preparation and administration are provided. Preferred embodiments provide sumatriptan succinate in a potassium phosphate buffer, wherein when a unit dose volume of about 50 to about 600 mcL of the oral spray composition is sprayed, a blood concentration of greater than about 5 ng/ml of sumatriptan is reached within about six minutes post dosing.

Abstract: Stable formulations of an active pharmaceutical agent suitable for oral spray administration for absorption by the oral mucosa and related methods of preparation and administration of active pharmaceutical agent formulations are provided. Preferred embodiments of the invention provide formulations comprising an active pharmaceutical agent, a solvent, a buffer, and a viscosity modifying agent, wherein when a unit dose volume of about 25 to 400 mcL of the oral spray composition is sprayed, the spray has a median particle size diameter of about 40 to about 100 microns.

Abstract: A liquid aerosol formulation comprising at least one thermally stable active ingredient selected from the group consisting of butalbital, lorazepam, ipratropium, baclofen, morphine, scopolamine, pharmaceutically acceptable salts and esters thereof and derivatives thereof. The liquid formulation can include an organic solvent such as propylene glycol and one or more optional excipients. The active ingredient can be present in an amount of 0.01 to 5 weight percent and the formulation can be heated to provide a vapor which forms an aerosol having a mass median aerodynamic diameter of less than 3 ?m.

Abstract: 1,1,1,2,3,3,3-heptafluoropropane (HFC-227) has been identified as a highly polar propellant. Surfactants which have an elevated value (9.6 or greater) for their hydrophilic-lipophilic balance (HLB) can be used as suspending, wetting, and lubricating agents or cosolvents in metered dose inhaler (MDI) formulations pressurized with HFC-227 or propellant blends that contain HFC-227. Particularly preferred surfactants include polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan mono-oleate, polyethylene glycol 300, propoxylated polyethylene glycol, polyoxyethylene 4 lauryl ether, and diethylene glycol monoethyl ether.
