  • Aerosol formulations of peptides and proteins
    Patent number: 6524557
    Abstract: A pharmaceutical aerosol formulation comprising (a) a HFA propellant; (b) a pharmaceutically active polypeptide dispersible in the propellant; and (c) a surfactant which is a C8-C16 fatty acid or salt thereof, a bile salt, a phospholipid, or an alkyl saccharide, which surfactant enhances the systemic absorption of the polypeptide in the lower respiratory tract. The invention also relates to methods of manufacturing such formulations and the use of such formulations in treating patients.

  • Method and system for measuring a dose of drug inhaled
    Patent number: 5887586
    Abstract: In a method for measuring a dose of a drug inhaled by an animal, the momentary concentration of the drug in an aerosol supplied to the animal and the momentary inhalation flow rate of the animal are determined. An inhaled partial dose is calculated from each determined inhalation flow rate value and a corresponding concentration value. The calculated inhaled partial doses are added to obtain the total dose inhaled by the animal.
