  1. 1. Water-swelling tablets based on hydrophobically modified poly(acrylic acid) - Effects of amphiphiles on swelling and drug release

    Författare :Patrik Knöös; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drug deliver; Controlled release; Hydrophobically modified polymers; Surfactant-polymer interactions; Poorly soluble drug;

    Sammanfattning : An important issue within the pharmaceutical world today is the increasing number of poorly soluble drugs. These often show a low bioavailability and a susceptibility to varying conditions in the intestine. LÄS MER

  3. 2. Levodopa pharmacokinetics -from stomach to brain : A study on patients with Parkinson’s disease

    Författare :Maria Nord; Nil Dizdar; Jonas Lind; Peter Söderkvist; Filip Bergquist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Parkinson’s disease (PD) is one of the most common neurodegenerative disorders and it is caused by a loss of dopamine (DA) producing neurons in the basal ganglia in the brain. The PD patient suffers from motor symptoms such as tremor, bradykinesia and rigidity and treatment with levodopa (LD), the precursor of DA, has positive effects on these symptoms. LÄS MER

  4. 3. Optical spectroscopy of turbid media: time-domain measurements and accelerated Monte Carlo modelling

    Författare :Erik Alerstam; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Optical spectroscopy is a versatile and powerful tool to probe translucent materials. In this work, the focus is on characterization of strongly scattering (turbid) materials by means of time-of-flight spectroscopy (TOFS). LÄS MER

  5. 4. Mechanistic Modelling of Drug Dissolution and Matrix Formulations: Rotating Disc Dissolution, Dissolution in a Stagnant Medium, Swelling and Dissolving Matrix Systems

    Författare :Erik Kaunisto; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rotating Disc; Diffusion; Dissolution; Controlled Release; Hydrophilic matrices; ESPI;

    Sammanfattning : Popular Abstract in Swedish Under årens lopp har människan gjort stora landvinningar inom läkemedelsforskning, vilket har lett fram till avancerade läkemedel som idag tas för givna. Avancerade läkemedel sätter dock höga krav på tillverkarna av läkemedel, vilket har lett till att framtagandet av nya läkemedel är en ganska komplicerad process. LÄS MER

  7. 5. Dissolution of Polydisperse Polymers in Water

    Författare :Anna Körner; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; PEO; swelling; polymer dissolution; polydispersity;

    Sammanfattning : The different steps in the dissolution process of polydisperse polymers in water have been studied. To that end, poly(ethylene oxide), dextran and hydroxypropyl methylcellulose tablets varying widely in polydispersity have been produced by mixing low molecular weight and high molecular weight samples in different proportions.
