  4. 2. Prolonged Drug Release from Gels, using Catanionic Mixtures

    Author : Tobias Bramer; Katarina Edsman; Per Hansson; Stefan Ulvenlund; Uppsala universitet; []
    Keywords : Pharmaceutics; gel; catanionic; vesicle; micelle; controlled release; diffusion; surfactant; drug delivery; Galenisk farmaci;

    Abstract : The use of catanionic drug-surfactant mixtures was proven to be an efficient novel method of obtaining prolonged drug release from gels. It was shown that various commonly used drug compounds are able to form catanionic mixtures together with oppositely charged surfactants. READ MORE

  5. 3. Studies on a Novel Powder Formulation for Nasal Drug Delivery

    Author : Nelly Fransén; Erik Björk; Katarina Edsman; Lars Hovgaard; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nasal drug delivery; nasal powder spray; interactive mixture; mucoadhesion; sodium starch glycolate; superdisintegrant; bioavailability; clinical trial; Pharmaceutics; Galenisk farmaci;

    Abstract : Nasal administration has potential for the treatment of indications requiring a fast onset of effect or for drugs with low oral bioavailability. Liquid nasal sprays are relatively common, but can be associated with suboptimal absorption from the nasal cavity; this thesis shows that nasal absorption can be significantly enhanced with a dry powder formulation.

  6. 4. Polymer Gels as Pharmaceutical Dosage Forms : Rheological Performance and Physicochemical Interactions at the Gel-Mucus Interface for Formulations Intended for Mucosal Drug Delivery

    Author : Helene Hägerström; Katarina Edsman; Arne Brodin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; gel; rheology; mucoadhesion; mucosal drug delivery; in situ gel; gellan gum; Carbopol; tensile strength; nasal mucosa; intranasal administration; dielectric spectroscopy; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : Drug delivery to the nasal and ocular mucosa faces several obstacles. One of these is from the effective clearance mechanisms present in the nose and eye. Polymer gels with suitable rheological properties can facilitate the absorption of poorly absorbed drugs by increasing the contact time of the drug with the mucosa. READ MORE
