Publication number: 20240050670Abstract: Systems and methods for isolating and/or desiccating a portion of a drug delivery tract of a drug delivery apparatus to reduce water vapor content therein are provided. For example, there is provided a metered dose inhaler for delivering aerosolized medicament or other matter to a user. The aerosolized medicament or other matter may be discharged from a discharge passageway within the inhaler into an inhalation passageway for inhalation by a user, and the inhaler may comprise a seal member operative to selectively isolate the discharge passageway from the inhalation passageway and external environment during inactivity. The inhaler may further comprise a desiccant material arranged to withdraw moisture from the isolated discharge passageway. In other instances, desiccant material may be arranged to withdraw moisture from the discharge passageway of the inhaler without isolating the discharge passage during inactivity.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Inventors: Matthew Ferriter, Denny Himel, Brian Foster, Michael L. King, Dan Deaton, Fred Hamlin, Jill Sherwood, Sarvajna Kumar Dwivedi, Robert V. Sheehy, JR.

Publication number: 20080064674Abstract: Disclosed are metered dose inhalers having a metering valve to deliver a dose containing an aerosol suspension formulation, said aerosol suspension formulation comprising: an effective amount of Mometasone Furoate, Formoterol or a combination thereof; a suspension medium selected from the group consisting of 1,1,1,2,3,3,3,-heptafluoropropane, 1,1,1,2-tetrafluoroethane; and a solvent that is ethanol; wherein said formulation contains less than about 500 ?g of non-volatile residue as measured by ultraviolet spectroscopy.Type: ApplicationFiled: November 14, 2007Publication date: March 13, 2008Inventors: Julianne Berry, Jill Sherwood, Saeed Chaudhry, Joel Sequeira

Publication number: 20060110443Abstract: A drug delivery device such as an oral dosage form (ODF) with a toxic or potent core encapsulated by a non-toxic region. The non-toxic region may be a region including multiple layers, coatings, shells, and combinations thereof, which provides protection to and isolation from the toxic or potent core. The drug in the toxic or potent core is incorporated into the dosage form via, for example, three-dimensional printing, as a solution, solubilization or suspension of solid particles in liquid, rather than by the more conventional handling and compressing of dry powder. This minimizes the likelihood of creating airborne particles of the toxic drug during manufacturing, hence controlling and minimizing the exposure of manufacturing personnel to the hazardous substance. Wet dispensing of the toxic or potent drug further provides greater bioavailability of the drug to the patient.Type: ApplicationFiled: October 7, 2005Publication date: May 25, 2006Applicant: Massachusetts Institute of TechnologyInventors: Francis Payumo, Jill Sherwood, Donald Monkhouse, Jaedeok Yoo, Christopher Gaylo, Chen-Chao Wang, Michael Cima
