5. Research Experience:
MSc. Pharmaceutics: The
research topic is (Pharmaceutical study on prolonged release solid dosage forms
of certain statins)
Summary of the research topic: preparation
of a controlled release solid dosage forms of simvastatin (tablets and
capsules) that fulfil the requirements for extended release medications using
different hydrophilic and hydrophobic polymers, evaluation of the release rate
profiles, physical and chemical stability and bioavailability determination. It
could be concluded from this research study that; simvastatin could be
formulated into different solid dosage forms that show physical and chemical
stability and offer optimum drug release required for controlled release
formulations
PhD Clinical Pharmacy: The
research topic is (Urinary Pharmacokinetic Methodology to Determine the
Relative Lung Bioavailability of Inhaled Beclometasone)
Summary
of the research topic: Development and application of a urinary pharmacokinetic
methodology to assay urine beclometasone concentrations and determine the
relative lung and systemic bioavailability together with in-vitro studies
to determine the aerodynamic characteristics when using different inhalation
methods. The research study highlights the extension of the urinary
pharmacokinetic method to inhaled beclometasonedipropionate and demonstrates
its usefulness to compare different inhalation methods and different
formulations. It also provides further evidence of in-vitro in-vivo correlations
between the urinary methodology and the aerodynamic characteristics of the
emitted dose

PHD Title
urinary pharmacokinetic method to determine the relative lung bioavailability of inhaled beclometasone
PHD Abstract
Urinary Pharmacokinetic Methodology To Determine The Relative Lung Bioavailability Of Inhaled Corticosteroids
Urinary pharmacokinetic methods have been introduced to identify the relative lung and systemic availability of inhaled drugs but have not been extended to corticosteroids. The main aims were to validate the urinary pharmacokinetic methodology when applied to inhaled beclometasone dipropionate (BDP), demonstrate the usefulness of the method and compare its indices to the in-vitro characteristics of the emitted dose.
A simple and sensitive LC-MS method for quantifying BDP and its metabolites in methanol (for in-vitro studies) and urine samples was identified and validated in accordance with the FDA and ICH guidelines. The accuracy, precision, and recovery of the method were within acceptable limits (±15%).
Twelve healthy volunteers completed the in-vivo urinary pharmacokinetic validation of the methodology to determine the relative lung bioavailability of inhaled beclometasone following inhalation. Twelve healthy volunteers received randomised doses, separated by >7 days, of 2000µg BDP solution with (OralC) and without (Oral) 5g oral charcoal, ten 100µg inhalations from a Qvar® Easi breathe metered dose inhaler (pMDI) with (QvarC) and without (Qvar) oral charcoal and eight 250µg inhalations from a Clenil® pMDI (Clenil). Subjects provided urine samples at 0, 0.5, 1, 2, 3, 5, 8, 12, and 24 hours post study dose. Urinary concentrations of BDP and its metabolites, 17-beclometasone monopropionate (BMP) and beclometasone (BOH) were measured. No BDP, BMP, or BOH was detected in any samples post OralC dosing. Post oral dosing, no BDP was detected in any of the urine samples and no BMP or BOH was excreted in the first 30 minutes. Significantly more (p<0.001) BDP, BMP and BOH was excreted in the first 30 minutes and cumulative 24 urinary excretions post Qvar and Clenil compared to Oral. Using 30 minute urinary excretion the mean ratio (90% confidence interval) for Qvar compared to Clenil was 231.4 (209.6, 255.7). The results confirm that the relative lung and systemic bioavailability can be identified from urinary excretion of BDP and its metabolites over the first 30 minutes and 24 hours respectively. The 2-fold difference between Qvar and Clenil is consistent with related clinical and pharmacokinetic studies. The low inter and intra-subject variability of the study confirms the reproducibility of this method. When compared to the in-vitro aerodynamics characteristics of the emitted dose, using standard compendial methods, the in-vivo indices showed a relationship to the fine particle dose (FPD) and the emitted dose (ED), respectively.
The application of this urinary pharmacokinetic method was demonstrated in further studies to compare the effect of different spacers and different washing methods on the in-vivo drug delivery post inhalation from Clenil and Qvar inhalers in healthy volunteers. In addition, the in-vitro aerodynamic particle size distribution of the same inhalation methods has been investigated using the Andersen Cascade Impactor according to the standard compendial methodology. Urinary excretion, using 24 hour excretion, revealed that relative bioavailability to the body was reduced with spacers for both inhalers. There was no increase in the relative lung bioavailability when Qvar was used with spacers. When Clenil was attached to a spacer (either AeroChamber or Volumatic) the relative lung bioavailability was significantly greater only if the spacers were not rinsed after washing with detergents. Consistent with the above study there were correlations between the in-vivo urinary indices and the in-vitro characteristics of the emitted dose.
The thesis highlights the extension of the urinary pharmacokinetic method to inhaled beclometasone dipropionate and provides further evidence of in-vitro in-vivo correlations between the urinary methodology and the aerodynamic characteristics of the emitted dose.
Keys words: beclometasone dipropionate, metabolites, urinary excretion, metered dose inhalers, spacers, relative lung bioavailability, and in-vitro dose emission.
