  1. 1. 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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Susanne Bredenberg; Uppsala universitet.; [2003]
    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; PHARMACY Pharmaceutics; FARMACI 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.

  2. 2. Studies on a Novel Powder Formulation for Nasal Drug Delivery

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nelly Fransén; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nasal drug delivery; nasal powder spray; interactive mixture; mucoadhesion; sodium starch glycolate; superdisintegrant; bioavailability; clinical trial; PHARMACY Pharmaceutics; FARMACI 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.

  3. 3. Drying of Multicomponent Liquid Films

    University dissertation from Stockholm : Kemiteknik

    Author : Fabio Luna; KTH.; [2004]
    Keywords : ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

    Abstract : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. READ MORE

  4. 4. An Analytical Solution Applied to Heat and Mass Transfer in a Vibrated Fluidised Bed Dryer

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Apolinar Picado; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical solution; Heat and mass transfer; Temperature and moisture distribution; Drying modelling; Multicomponent drying; Drying selectivity; Volatile retention; Ternary mixture; Drying of particulate materials; Vibrated fluidised bed dryer; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : A mathematical model for the drying of particulate solids in a continuous vibrated fluidised bed dryer was developed and applied to the drying of grain wetted with a single liquid and porous particles containing multicomponent liquid mixtures. Simple equipment and material models were applied to describe the process. READ MORE

  5. 5. Transport Coefficients during Drying of Solids containing Multicomponent Mixtures

    University dissertation from Stockholm : KTH

    Author : Rafael Gamero; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary; conduction; convection; diffusion; evaporation; heat transfer; hydraulic conductivity; liquid film; liquid transport; mass transfer; Maxwell-Stefan diffusion coefficients; molar fluxes; phase equilibrium; temperature gradient; ternary mixture; thermodynamic factors; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : This study investigated the transport coefficients involved in mass and heat transfer during the drying of a porous solid partially saturated with multicomponent mixtures.  It included the coefficients governing liquid transport through the solid, the matrix of multicomponent diffusion coefficients in the liquid phase, and the effective thermal conductivity.
