  1. 1. The effect of lactose fines, magnesium stearate, choice of mixer and mixing process on the performance of adhesive mixtures for inhalation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Gabriela Ponce Aparicio; [2023]
    Nyckelord :High shear mixing; low shear mixing; lactose fines; coating agent; budesonide; mixing energy; dry powder inhaler; carrier-based formulations; mixing time; adhesive mixtures; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Dry powder inhaler (DPI) formulation is a major area of interest since they are employed by the healthcare system to treat relevant chronic diseases like asthma. Previous research has established that the manufacturing process and formulation composition are key for the active pharmaceutical ingredient to reach the lungs and achieve therapeutic effects.

  3. 2. Models for estimating radiation dose and LAR from radioactive fallout: extended dose algorithms for the computational tool LARCalc

    Master-uppsats,

    Författare :Jonathan Sundström; [2022-09-09]
    Nyckelord :Medical physics; Nuclear power plant; Radiation dose; Effective dose; Lifetime attributable risk; LAR; Fallout; Inhalation; Strontium-90; Iodine-131; Cloudshine;

    Sammanfattning : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. LÄS MER

  4. 3. Characterization of the effect of the membrane on in vitro dissolution profiles for pulmonary drug delivery

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaci

    Författare :Maral Simonides; [2021]
    Nyckelord :Oral inhalation; in vitro dissolution; Budesonide; Fluticasone propionate; Transwell;

    Sammanfattning : It has always been a challenge to imitate the lung environment, therefore there is a constant development of standardized in vitro dissolution methods for inhaled products. Dissolution in vitro has been considered as an important parameter, because low solubility determines the bioavailability of inhaled drugs. LÄS MER

  5. 4. Bacillus anthracis : naturliga utbrott, bioattacker och veterinärens roll

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Olivia Nordfeldt; [2017]
    Nyckelord :Bacillus anthracis; antrax; biovapen; biologiska krigföring; bioterrorism;

    Sammanfattning : Biologisk krigföring är inte ett nytt begrepp, tvärtom har forskare hittat mängder av exempel på sådana attacker redan från medeltiden, och ännu längre bakåt i tiden. Framväxten av den moderna mikrobiologin på 1900-talet, startade dock ett helt nytt kapitel och det var plötsligt möjligt att uppföröka stora mängder patogener. LÄS MER

  7. 5. Designing a digital inhaler

    Master-uppsats, Lunds universitet/Innovation

    Sammanfattning : Untreated asthma limits the ability to live an active life, still many asthmatics does not have the level of control over their asthma as they could have. In addition, about 50% of the asthmatics use their inhaler incorrectly, which affects the result of the medicine negative. LÄS MER
