Use Of Structure-And Ligand-Based Drug Design Tools For The Discovery Of Small Molecule Inhibitors Of Cysteine Proteases For The Treatment Of Malaria And Sars Infection, Falgun Shah

Electronic Theses and Dissertations

A wide array of molecular modeling tools were utilized to design and develop inhibitors against cysteine protease of P. Falciparum Malaria and Severe Acute Respiratory Syndrome (SARS). A number of potent inhibitors were developed against cysteine protease and hemoglobinase of P. falciparum , referred as Falcipains (FPs), by the structure-based virtual screening of the focused libraries enriched in soft-electrophiles containing compounds. Twenty one diverse, non-peptidic, low micromolar hits were identified. A combined data mining and combinatorial library synthesis approach was performed to discover analogs of virtual screening hits and establish the structure-activity relationships (SAR). However, the resulting SAR of the …

Biopharmaceutical Approaches For Improved Drug Delivery Across Ocular Barriers, Ketan Hippalgaonkar

Electronic Theses and Dissertations

The eye is protected from the external environment by various physiological and anatomical barriers. These barriers through there protective actions drastically diminish the ocular bioavailability of drugs. The corneal epithelium acts as a major barrier towards the permeation of hydrophilic agents, whereas poor aqueous solubility presents a formulation challenge for lipophilic compounds. Additionally, P-glycoprotein (P-gp) expressed on the retinal pigmented epithelium (RPE P-gp) limits the penetration of substrates, in therapeutically relevant concentrations, into the back-of-the-eye.

In the present research, use of penetration enhancers (chitosan, benzalkonium chloride (BAK) and ethylenediaminetetraacetic acid (EDTA)) and formulation approaches (cyclodextrins and solid lipid nanoparticles (SLNs)) …

Case-Mix Adjustment Of Adherence Based Pharmacy Quality Indicator Scores, Sai Hurrish Dharmarajan

Electronic Theses and Dissertations

Medication adherence has been shown to be influenced by demographics, health status and socio-economic status of the patient. Thus, adherence-based measures of pharmacy quality may be influenced by patient-related risk factors outside of the healthcare provider's control. This study examines the performance of a classical logistic regression model containing only patient characteristics and a random-effect model including patient characteristics and a pharmacy-specific effect in predicting medication adherence. These models were used to compute three different risk-adjusted scores on adherence-based pharmacy quality indicators: based on the classical logistic regression model (Method 1), the random effects model (Method 2) and the shrinkage …

Nose To Brain Delivery Of Therapeutic Agents, Siva Ram Kiran Vaka

Electronic Theses and Dissertations

The potential treatment approaches for various disorders associated with central nervous system are invasive and do not allow frequent administration. Brain targeting of drugs by intranasal route is a safe and noninvasive method of drug delivery which allows frequent administration and is certainly more patient compliant than the currently folloinvasive methods. In this study, the plausibility of delivering neurotrophins [nerve growth factor (NGF) and brain derived neurotrophic factor (BDNF)], neurotrophinogenic agents (ex: carnosic acid) and antibiotics (ex: cefotaxime) to brain via nose-brain pathway using chitosan as barrier modulating agent was investigated. In vitro permeation studies of fluorescein isothiocyanate dextran (FD40k) …

Pharmacists' Rating Of Relevance Of Available Information In Deciding The Validity Of Opioid Medication Prescriptions, Leonardo Roberto Torres

Electronic Theses and Dissertations

Pharmacists are tasked with making decisions regarding the validity of prescriptions. Some have proposed factors that should be considered when evaluating a prescription's validity. Yet, there is little known about the decision process that pharmacists employ at the time of dispensing and what information pharmacists deem relevant in that decision-making process. Using an online survey instrument, a sample of community pharmacists were divided into three groups and presented with a prescription scenario. They were asked to rate the relevance of information, which is proposed to be appropriate and inappropriate, available at the time of dispensing. They were asked to consider …

Willingness To Influence Indication-Based Off-Label Prescribing: An Investigation Of Hospital Pharmacists, Ram Sankar Basak

Electronic Theses and Dissertations

Off-label prescribing is a comand legal practice in the United States. However, off-label prescribing occurs oftentimes with inadequate evidence of effectiveness. Such practice, especially when prescribing for disease conditions different from approved clinical indications (indication-based off-label prescribing), brings about controversy and raises different issues with various stakeholders. Although indication-based off-label prescribing offers advantages in terms of providing innovative therapy, it raises concerns because the safety and efficacy of such use may not be evaluated adequately. Thus, the objective of the study was to examine whether pharmacists are willing to influence physicians while evaluating an indication-based off-label medication order. Based on …
