    Sammanfattning : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. LÄS MER

  2. 2. Geopolymer-based drug formulations for oral delivery of opioids

    Detta är en avhandling från Uppsala : Uppsala University, Department of Engineering Sciences

    Författare :Bing Cai; Uppsala universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Opioid therapy for chronic pain generally use controlled release formulations to deliver analgesic drugs around-the-clock. Controlled release dosage forms can enlarge the therapeutic effect by controlling the rate and site of release. However, with high drug content, opioid formulations are easily targeted for non-medical use. LÄS MER

  3. 3. Ceramic Materials for Administration of Potent Drugs

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Bing Cai; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tamper-resistance; Oral formulation; Transdermal formulation; Biomaterials; Microneedles;

    Sammanfattning : This thesis aimed to investigate and document the potential of applying ceramics in two specific drug delivery applications: tamper-resistant opioid formulations and transdermal enhancement protrusions.Geopolymers were developed into the matrix for a tamper-resistant formulation, aiming to protect drug substances from non-medical abuse.
