Publication number: 20030207057Abstract: A metered dose inhaler having part or all of its internal surfaces coated two or more times with a polymer comprising one or more fluorocarbon polymers, optionally in combination with one or more non-fluorocarbon polymers, containing an inhalation drug or a physiologically acceptable salt thereof, optionally an excipient and a fluorocarbon propellant. Also, a method for coating all or part of internal surfaces of a metered dose inhaler can comprising applying a first coat comprising a one or more fluorocarbon polymers to all or part of the internal the surfaces of a metered dose inhaler can. Subsequently, heating the first coat of fluorocarbon polymer and then applying a second coat comprising one or more fluorocarbon polymer on top of the first coat of fluorocarbon polymer. The two coats of fluorocarbon polymer are then heated to give a metered dose inhaler can that is more efficient in dispensing consistent doses of aerosol formulations.Type: ApplicationFiled: April 8, 2003Publication date: November 6, 2003Inventors: Ignatius Loy Britto, William McHale, Laurence McKeen, Michael Witsch

Patent number: 6098619Abstract: An inhaler apparatus having a housing having first and second walls and defining an air inlet and an air outlet. The first and second walls define an internal housing volume and have portions being movable relative to each other so as to expand the internal housing volume from a non-inhalation state, wherein the internal housing volume has a first volume, to an inhalation state, wherein the internal housing volume has a second volume. The second volume is larger than the first volume. An air flow chamber is defined within the housing between the air inlet and the air outlet when the housing is in the inhalation state. A medicament is contained between the first and second walls. The medicament is exposed within the air flow chamber when the housing is in the inhalation state.Type: GrantFiled: April 29, 1999Date of Patent: August 8, 2000Assignee: Glaxo Wellcome Inc.Inventors: Ignatius Loy Britto, Jason Christopher Billig, Fredric Scott Stiber
