Production and characterisation of spray dried particulate systems for pulmonary drug delivery
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2009)The work presented in this thesis concerns the application of a particle engineering technology, one-step spray drying method, to produce porous particles of antitubercular drugs, suitable for inhalation and to study the ... -
Simulations of hydrodynamics in the paddle dissolution apparatus and dissolution from multi-layered compacts
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2003)Studies involving the calculation of dissolution rates from individual surfaces of large single component compacts, to assist in the prediction of dissolution rates from simple layered compact systems, revealed that ... -
Solid-state characteristics of pre- and post-spray dried active pharmaceutical ingredients, salts and co-crystalline forms
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2011)Salt or co-crystal formation is one of the methods of altering the physicochemical properties of an active pharmaceutical ingredient (API). The drug characteristic can also be changed upon processing. This thesis focused ... -
Synthesis, characterisation and drug release from a range of novel smart co-biodegrable delivery systems
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2008)In recent years many biodegradable polymers have been investigated particularly for controlled delivery of drugs or proteins/peptides. The most commonly studied biodegradable polymers for controlled drug delivery are based ... -
The effect of processing on the solid state characteristis of selected sulphonamides and their sodium salts, alone and as drug-salt composites
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)The purpose of the research presented in this thesis was to produce metastable active pharmaceutical ingredients (API) by spray drying and to analyse, physico-chemically characterise these forms and develop strategies to ... -
The influence of drug physicochemical properties on release from thermoresponsive smart hydrogels
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2005)Thermoresponsive hydrogels are a class of "smart" or "environmentally sensitive" systems with potential for controlling the release of a drug in response to a specific stimulus. Previous research in the area of thermoresponsive ... -
The production and characterisation of spray dried nanoporous microparticles (NPMPs) intended for dry powder inhalation drug delivery systems
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2008)The focus of the research presented in this thesis was on the potential application of a novel spray drying method to produce excipient-free nanoporous microparticles (NPMPs) of bioactive drug compounds and co-spray dried ... -
Use of computational fluid dynamics to investigate the relationship between hydrodynamics and rates of dissolution
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2007)The hydrodynamics within the paddle (900 ml), basket (900 ml) and Levy beaker (350 ml and 550 ml) (Levy et al., 1965) dissolution apparatuses were simulated using the computational fluid dynamics (CFD) package, Fluent™. ...
