  2. 16. The Horizontal Ussing Chamber Method in Studies of Nasal Drug Delivery : Method Development and Applications Using Different Formulations

    Author : Karin Östh; Anna-Lena Ungell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Abstract : The results from this thesis leads to the following conclusions; HUM is a useful tool that fills a gap in the in vitro methods previously available to study nasal drug delivery. Using HUM, the pig respiratory nasal mucosa can obtain acceptable viability and retain it longer than the period of time needed for a transport experiment. READ MORE

  4. 17. Engineering of Pharmaceutical Particles : Modulation of Particle Structural Properties, Solid-State Stability and Tabletting Behaviour by the Drying Process

    Author : Jonas Berggren; Göran Alderborn; Graham Buckton; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; particle engineering; microcrystalline cellulose pellets; intragranular porosity; convective drying; tabletting behaviour; spray-dried composite particles; amorphous lactose; PVP; heat and moisture-induced crystallisation; glass transition temperature; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Relationships between stresses during the drying process, particle structural and functional properties, and particle engineering by the drying process were addressed in this thesis. In the first part, the importance of the drying phase and the effect of the drying rate on the intragranular porosity of microcrystalline cellulose pellets were investigated. READ MORE

  5. 18. Computational and Experimental Models for the Prediction of Intestinal Drug Solubility and Absorption

    Author : Christel A. S. Bergström; Per Artursson; Han van de Waterbeemd; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; aqueous drug solubility; melting point; intestinal drug permeability; pH-dependent solubility; multivariate data analysis; molecular descriptors; molecular surface area; in silico modeling; drug absorption; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the number of new drugs undergoing clinical trial has not augmented at the same pace, which in part has been attributed to poor absorption of the compounds. READ MORE

  6. 19. New Concepts in Administration of Drugs in Tablet Form : Formulation and Evaluation of a Sublingual Tablet for Rapid Absorption, and Presentation of an Individualised Dose Administration System

    Author : Susanne Bredenberg; Christer Nyström; Carla Caramella; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Interactive mixture; Dose homogeneity; Disintegration; Bioadhesion; Oromucosal delivery; Sublingual tablet; Rapid absorption; Individual dosage; Drug dispensing device; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : This thesis presents two new concepts in oral drug administration and the results of evaluation of some relevant formulation factors.Investigation into improving the homogeneity of mixtures for tableting indicated that it may be possible to obtain interactive dry mixtures of micronised drugs containing drug proportions as low as 0.015% w/w.
