Cocrystal habit engineering to improve drug dissolution and alter derived powder properties
(2016)Objectives: Cocrystallization of sulfadimidine (SDM) with suitable coformers, such as 4-aminosalicylic acid (4-ASA), combined with changes in the crystal habit can favourably alter its physicochemical properties. The aim ... -
Emerging nanonisation technologies: tailoring crystalline versus amorphous nanomaterials
(2015)The overall pharmaceutical market is changing. A more personalised medicine approach is replacing the concept of blockbuster drugs and the “one size fits all” model. The two main forces that fuel the growth of nano-enabled ... -
Development of a novel dry powder inhalation formulation for the delivery of rivastigmine hydrogen tartrate
(2016)he purpose of this study was to prepare engineered particles of rivastigmine hydrogen tartrate (RHT) and to characterize the physicochemical and aerodynamic properties, in comparison to a lactose carrier formulation (LCF). ... -
Comparative evaluation of rivastigmine permeation from a transdermal system in the Franz cell using synthetic membranes and pig ear skin with in vivo-in vitro correlation
(2016)In the present study, in vitro permeation experiments in a Franz diffusion cell were performed using different synthetic polymeric membranes and pig ear skin to evaluate a rivastigmine (RV) transdermal drug delivery system. ... -
Mitigating unwanted amorphisation: A screening method for the selection of suitable excipients
(2016)Co-processing an active pharmaceutical ingredient (API) with a low Tg excipient has been previously reported to be an effective strategy for preventing drug amorphisation on milling. This technique relies on the ability ... -
Novel Selective Butyrylcholinesterase Inhibitors Incorporating Antioxidant Functionalities as Potential Bimodal Therapeutics for Alzheimer's Disease
(2016)sosorbide-2-carbamates-5-aryl esters are highly potent and very selective butyrylcholinesterase inhibitors. The objective of the present work was to address the hypothesis that the isosorbide-aryl-5-ester group could be ... -
A Central Role for Monocyte-Platelet Interactions in Heart Failure
(2015)Heart failure (HF) is an increasingly prevalent and costly multifactorial syndrome with high morbidity and mortality rates. The exact pathophysiological mechanisms leading to the development of HF are not completely ... -
The synthesis of novel mast cell stabilisers from benzocycloalkanones
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2010)The purpose of this project was to design and synthesise novel classes of mast cell stabilisers from benzocycloalkanones. This thesis is introduced with an overview of the increasing prevalence of allergic conditions ... -
Investigations into the anti allergy properties of novel benzocycloalkanone based compounds
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2010)An allergic response occurs because of a hypersensitive response by mast cells to an otherwise innocuous environmental substance. Allergen challenge causes mast cell degranulation, resulting in the release of mast cell ... -
Endothelium as a target in the design of novel tumour antiangiogenic / vasculature-targeting agents
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2008)This thesis begins with a review of tumour growth and development, with a particular focus on angiogenesis. The numerous mechanisms which regulate the process are touched upon, with current and fiiture antiangiogenic agents ... -
Formulation and characterisation of polyelectrolyte complex nanoparticles for the delivery of salmon calcitonin
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)The studies in this thesis explored the formulation of various polyelectrolyte complex nanoparticles as potential carriers for the delivery of macromolecules. The complexes were formed between a polyanion (hyaluroninc acid, ... -
Caffeine exacerbates the toxicity of 3,4 methylenedioxymethamphetamine (MDMA, Ecstasy ) : a role for dopamine
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2010)Co-administration of caffeine profoundly enhances the acute toxicity of the substituted amphetamine 3, 4-methylenedioxymethamphetamine (MDMA “Ecstasy”) in rats, evidenced by high body temperature, tachycardia and increased ... -
Investigations of physicochemical properties of spray dried drug-excipient composites directed to inhalable products
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2005)The studies in this thesis explored the solid state and inhalation properties of various systems produced by the spray drying technique. The work focused on the feasibility analysis of spray drying as a means of producing ... -
Liposomes as carriers for systemic delivery of salmon calcitonin by inhalation
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2011)The concept of delivering proteins and peptides to the systemic circulation via the lungs has been extensively investigated over the last 20 years. Main drivers for the approach are the lungs’ high surface area, presumed ... -
A pharmacokinetic and clinical evaluation of antimicrobial drugs in critically ill patients during Continuous Venovenous Haemodifiltration (CVVHDF) therapy
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2007)Critically ill patients are at risk from sepsis requiring antimicrobial therapy and acute renal failure, which may require extracorporeal renal replacement therapy. The objective of this study was to quantify and assess ... -
Investigation into bile acid effects on the golgi apparatus, cell viability and glucocorticoid receptor distribution in esophageal cells
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2010)Bile acids are a family of steroidal molecules derived from cholesterol and biosynthesised in the pericentral hepatocytes in the liver. In recent years there has been a renaissance in bile acid based research as it has ... -
Functional expression of the epithelial sodium channel δ-subunit in human respiratory epithelial cells
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2012)Mammalian amiloride-sensitive epithelial Na+ channel (ENaC) can be composed by different combinations of four homologous subunits, α, β, γ and δ. The canonical αβγ- ENaC, abundantly expressed in Na+ absorbing epithelia, ...
