Book Description
This book details the latest research and development in the use of magnetic resonance imaging and spectroscopy as tools to give quantitative insights concerning late stage pharmaceutical formulation, tablet manufacturing and drug dissolution behaviour. The book combines different facets of magnetic resonance and highlights the use of spatial resolution (MRI) and how this adds to the knowledge base to further our understanding of the microscopic physicochemical processes occurring during drug release from solid dosage forms. New topics, that have not been thoroughly reviewed elsewhere, are covered including the applications of solution state magnetic resonance in process scale up, reaction monitoring/understanding and process analytical technologies (PAT); dissolution testing; and counterfeit analysis. Solid state NMR and its role in understanding phase separation in dispersions, polymorphism and crystallography are included and magnetic resonance imaging and its use in assessing tablet dissolution performance, mass transport and mixing in hot melt extrusion (HME) are covered. Focusing on late stage development rather than molecular drug discovery provides a unique approach and the book will appeal to a diversity of disciplines using spectroscopy for study. Aimed at researchers in drug development, manufacture and formulation in both industry (pharmaceutical companies) and academia (pharmacy program), it includes examples, where appropriate, of studies on commercially available pharmaceutical products.

Book Description
Magnetic resonance imaging (MRI) is a versatile imaging modality that can be a powerful tool for developing and improving drug delivery strategies. High field ([greater than or equal to]7T), small bore MR systems are increasingly available for preclinical research, and high field human systems are becoming available as well, thus promising easier translation of high field MR techniques to human medicine. The increased signal to noise at high field can be allocated to improving spatial resolution, which allows for earlier detection of both primary and metastatic neoplasias. Moreover, resolving smaller lesions also permits us to more fully characterize the development process of disease, such as the progression of permeability of metastatic brain lesions, which is an important consideration when choosing an appropriate therapeutic course. In addition to the general benefit of higher signal to noise at higher field, some methods, such as MR thermometry (via the proton resonance frequency shift), and more generally, any imaging method that attempts to resolve differences in resonance frequency/chemical shift, also benefit from the increased spectral separation, in absolute terms, at higher field strengths. Here, we examine MRI methods for improving drug delivery strategies including using real time MR thermometry in a closed loop with an MR compatible focused ultrasound system to provide a consistent acoustic dose in vivo. Further, we examine the use of paramagnetic micelles as a way to track the disposition of these small drug delivery vehicles, comparing peptide targeted to untargeted versions. We then extend our examination to the detection and characterization of small brain metastases followed by the imaging the vascular volume both for registration with PET images and estimation of the arterial input function as a step in pharmacokinetic modeling of vascular permeability. Finally, we examine displacement imaging techniques and successfully program and implement displacement imaging sequences for two purposes: adaptive focusing of an ultrasound beam without heating, and obtaining the shear modulus for evaluating tissue stiffness.

Book Description
NMR in Pharmaceutical Sciences is intended to be a comprehensive source of information for the many individuals that utilize MR in studies of relevance to the pharmaceutical sector. The book is intended to educate and inform those who develop and apply MR approaches within the wider pharmaceutical environment, emphasizing the toolbox that is available to spectroscopists and radiologists. This book is structured on the key processes in drug discovery, development and manufacture, but underpinned by an understanding of fundamental NMR principles and the unique contribution that NMR (including MRI) can provide. After an introductory chapter, which constitutes an overview, the content is organised into five sections. The first section is on the basics of NMR theory and relevant experimental methods. The rest follow a sequence based on the chronology of drug discovery and development, firstly 'Idea to Lead' then 'Lead to Drug Candidate', followed by 'Clinical Development', and finally 'Drug Manufacture'. The thirty one chapters cover a vast range of topics from analytical chemistry, including aspects involved in regulatory matters and in the prevention of fraud, to clinical imaging studies. Whilst this comprehensive volume will be essential reading for many scientists based in pharmaceutical and related industries, it should also be of considerable value to a much wider range of academic scientists whose research is related to the various aspects of pharmaceutical R&D; for them it will supply vital understanding of pharmaceutical industrial concerns and the basis of key decision making processes.

Book Description
Controlled release formulations for local, in vivo drug delivery are of growing interest to device manufacturers, research scientists, and clinicians; however, most research characterizing controlled release formulations occurs in vitro because the spatial and temporal distribution of drug delivery is difficult to measure in vivo. In this work, in vivo magnetic resonance imaging (MRI) of local drug delivery is performed to visualize and quantify the time resolved distribution of MRI contrast agents. I find it is possible to visualize contrast agent distributions in near real time from local delivery vehicles using MRI. Three dimensional T1 maps are processed to produce in vivo concentration maps of contrast agent for individual animal models. The method for obtaining concentration maps is analyzed to estimate errors introduced at various steps in the process. The method is used to evaluate different controlled release vehicles, vehicle placement, and type of surgical wound in rabbits as a model for antimicrobial delivery to orthopaedic infection sites. I are able to see differences between all these factors; however, all images show that contrast agent remains fairly local to the wound site and do not distribute to tissues far from the implant in therapeutic concentrations. I also produce a mathematical model that investigates important mechanisms in the transport of antimicrobials in a wound environment. It is determined from both the images and the mathematical model that antimicrobial distribution in an orthopaedic wounds is dependent on both diffusive and convective mechanisms. Furthermore, I began development of MRI visible therapeutic agents to examine active drug distributions. I hypothesize that this work can be developed into a non-invasive, patient specific, clinical tool to evaluate the success of interventional procedures using local drug delivery vehicles.
