This volume is the first-ever complete treatise on polymyxins and presents the most comprehensive and up-to-date reviews of all major research and clinical topics from chemistry, microbiology, pharmacology, clinical use, to drug discovery. All chapters were written by internationally leading researchers and clinicians in the field. It is our wish that readers discover the importance of polymyxin structure in relation to the mechanisms of activity, resistance and toxicity. We emphasized that reliable analytic methods for polymyxins are critical when investigating their pharmacokinetics (PK) and pharmacodynamics (PD). The complicated dose definitions and different pharmacopoeial standards have already compromised the safe use of polymyxins in patients. Therefore, informed by the latest pharmacological information, scientifically-based dosing recommendations have been proposed for intravenous polymyxins. Considering the PK/PD limitations and potential development of resistance, polymyxin combinations are encouraged; however, the current literature has not shown definite microbiological benefits, possibly because most clinical studies to date overlooked key PK/PD principles. Nephrotoxicity is the major dose-limiting factor and it is imperative to elucidate the mechanisms and develop novel approaches to minimize polymyxin-associated toxicities. In addition, the anti-endotoxin effect of polymyxins supports their clinical use to treat Gram-negative sepsis. Fortunately, the discovery of new-generation polymyxins with wider therapeutic windows has benefited from the latest achievements in polymyxin research. This book provides extensive pharmacological information on polymyxins to infectious diseases clinicians, pharmacists, clinical microbiologists, antimicrobial pharmacologists, and pharmaceutical scientists, and is an essential read for those who aim to develop novel polymyxins and improve their clinical use as a last-line defense against Gram-negative ‘superbugs’.

Optimizing Polymyxin Antibiotics Using Combination Therapy And Mechanism Based Models written by Neang S. Ly and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2014 with categories.

The emergence of multidrug-resistant (MDR) Gram-negative 'superbugs' coupled with a rapid decline in the development of new antibiotics has led to a serious, global health crisis. Polymyxin antibiotics, which include polymyxin E (colistin) and polymyxin B, were introduced over 50 years ago and were seldom used due to nephrotoxicity. However, recently, the polymyxins have re-emerged in the clinic as an antibiotic of last-resort. There are increasing reports of polymyxin resistance and failure during polymyxin monotherapy. While polymyxin based combination therapies are a promising alternative, there are significant gaps regarding the optimal use of such combinations. The primary goal of this dissertation is to rationally optimize polymyxin combination therapy based on pharmacokinetic/pharmacodynamic (PK/PD) principles. Menchanism-based (PK/PD) models (MBMs) were employed to evaluate mechanisms of antibiotic synergy. A secondary goal is to define the mechanisms of polymyxin tolerance and resistance utilizing genetically modified knockout strains and to develop MBMs that quantify the impact of bacterial regulatory systems including quorum sensing mechanisms on antibiotic PD.
