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 ... -
An investigation into the behavioural effects of polyamines, polyamine antagonsits and novel compounds in vivo
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2007)The polyamines, putrescine, spermidine and spermine are ubiquitous compounents of eukaryotric cells in nature and are found in high concentrations in brain tissue. Polyamines have been implicated in cell growth, differentiation ... -
A study of the release of the amphoteric drug amoxycillin from biodegradable polymers
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2000)Poly-alpha-hydroxy-aliphatic esters constitute a group of biodegradable polymers which have been actively investigated over the past three decades for the sustained release of drug compounds. A literature review revealed ... -
Characterisation of polymorphisms on the promoter region of the human histamine 4 receptor
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)The human histamine 4 receptor (HRH4) is the recently discovered receptor in the histamine GPCR family. It is mainly expressed in haematopoietic cells but recent publications provide evidence that it is both expressed and ... -
The development, validation and application of analytical methods for the analysis of drugs of abuse
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2001)There are five chapters presented in this thesis. The first chapter deals with development and validation of a HPLC method for the analysis of MDMA in illicitly produced Ecstasy tablets. In all 100 tablets were analysed ... -
Formulation, production and biointeraction of micro and nano particulates with potential for use in drug delivery
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2009)The current study involved the preparation of a range of micro and nano particulates from known biocompatible pharmaceutical polymeric excipients: PLGA, chitosan and hyaluronic acid, using physical rather than chemical ... -
Investigation of factors affecting dissolution under biorelevant low velocity hydrodynamic conditions, using in vitro and in-silico methods
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2011)The goals of the current study were to investigate the effect of hydrodynamics on the dissolution of non-disintegrating compacts in a low velocity environment. This work also studies the impact of hydrodynamics on the ... -
Absorption properties of non-steroidal anti-inflammatory drugs and their amino acid derivatives
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2003)The principal objectives of this work were: i) to examine the absorption properties of ibuprofen in a range of different buffer solutions; ii) to study the absorption properties and mechanisms of ibuprofen, ketoprofen and ... -
Polyamines and polyamine antagonists in cerebral ischaemia
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2005)Polyamines are ubiquitous components of all eukaryotic cells and are found in brain tissue. A number of studies have shown that changes in the levels of polyamines occur following cerebral ischaemia. However, whether ... -
An investigation of the role of the polyamines in epilepsy and cerebral ischaemia
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2001)The polyamines, spermine and spermidine, are ubiquitous in nature but are found in especially high concentrations in brain tissue. The polyamines are required for cell growth and differentiation but in high doses are ... -
The pharmacological effects of novel isosorbide-based butyrylcholinesterase inhibitors
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2009)This study sought to determine the pharmacological effects of novel isosorbide-based butyrylcholinesterase inhibitors (BuChEl’s) in vitro and in vivo. The potency of the novel compounds 2-benzylcarbamate 5-nicotinate ... -
Characterisation of drug-fatty acid composites and their use in drug delivery systems
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2000)Fatty acids are considered to be useful as carrier materials in the formulation of drug delivery systems. Literature on fatty acid systems, in particular, stearic acid, was reviewed, though in general, research in this ... -
Mechanistics aspects of the release of drugs from hydrophilic polymer matrices
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2001)Hydrophilic polymers, which both swell and erode, are widely used to produce sustained release of drugs from monolithic matrices, and have been extensively reviewed in the literature (Alderman 1984), (Peppas and Korsmeyer ... -
An investigation into the effects of current immunosuppressants and novel compounds on animal models of asthma and delayed type hypersensitivity
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2007)Asthma is a disease with a worldwide distribution and of increasing prevalence. There are two forms of the disease; intrinsic, which is believed to follow a Th1 cytokine profile and extrinsic, which follows a Th2 response. ... -
