An investigation into the use of ion-exchange resins as a formulation approach for modified-release oral liquid preparations
(Trinity College Dublin, Trinity College Dublin. School of Pharmacy & Pharma. Sciences. Discipline of Pharmacy, 2022)This thesis focuses on the use of ion-exchange resins (IERs) to modify the release profile of an active pharmaceutical ingredient (API) that would help address an unmet clinical need in the population if formulated as an ... -
Investigation of cerebral perfusion changes following MDMA Ecstasy administration in an animal model using bolus-tracking arterial spin labelling MRI
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2012)The recreational drug of abuse 3,4 methylenedioxymethamphetamine (MDMA; Ecstasy) carries a risk of cerebrovascular accidents (CVA) that may relate to the role of serotonin (5- HT) and/or dopamine in the regulation of ... -
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 ... -
Investigation of ibuprofen release from ethylcellulose matrix compacts
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2004)A comprehensive study of ethylcellulose powder and ethylcellulose compacts (of different ethylcellulose viscosity grades) was undertaken. Studies showed that the lower viscosity grade ethylcellulose (4 cP) was more ... -
Investigation of the PSD-95 / nNOS protein interaction as a target for antidepressant activity
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)Previous studies have demonstrated that nitric oxide (NO) synthase inhibitors are as efficacious as tricyclic antidepressants in preclinical antidepressant screening procedures and in attenuating behavioural deficits ... -
Investigation of the solid-state, powder flow and tabletability properties of comminuted active pharmaceutical ingredients
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)An understanding of the effect of processing on the solid-state properties of active pharmaceutical ingredients (APIs) is essential for product manufacturing success. During product development it is possible to induce ... -
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 ... -
Investigations of a spray-drying method for producing nanoporous / nano-particulate microparticles (NPMPs) of proteins and protein-excipient composites
(Trinity College (Dublin, Ireland).
