This book was released on 2015-06-04 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria takes a great toll on human health and well-being, particularly in tropical regions including Sub-Saharan Africa, Southeast Asia, Oceania and parts of the Americas. In recent years, some Plasmodium strains have become increasingly resistant to all classes of conventional antimalarial drugs currently in use. Researchers have, therefore, stepped up efforts to revise atimalarial drug policies, develop new drugs, and implement new strategies to combat this disease. In order to prevent widespread resistance, antimalarial combination therapies (ACTs) have been deployed and a World Antimalarial Resistance Network has been established as a means of anitimalarial drug resistance surveillance. Artemisinin-based combination therapies have proven to be useful as a replacement for standard regimens. Currently, these ACTs successfully cure patients suffering from uncomplicated malaria with superior efficacy and lower toxicity, but there remains a huge challenge (high mortality rate) associated with treatment of severe malaria. Studies of drug disposition and drug efficacy (PK/PD evaluations) are essential to understanding why drugs work as antimalarials as they illustrate issues with drug resistance, drug safety and drug toxicity that are critical to finding the appropriate drug dose for patients. This eBook illustrates how currently available combination antimalarial drugs can be optimized for effective malaria treatment. Chapters in this book explain methods to select combination drugs based on PK/PD evaluations followed by methods o reduce drug toxicity based on these evaluations. The book also summarizes efforts that are being made by the research community to improve ACT. It is, therefore, a handy reference for medical professionals and pharmacologists working on antimalarial drugs.

Download or read book Treatment and Prevention of Malaria written by Henry M. Staines and published by Springer Science & Business Media. This book was released on 2012-01-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria has defeated previous efforts at eradication and remains a massive global public health problem despite being readily preventable and treatable. It is a devastating disease that also extracts huge economic costs from the poorest countries in endemic regions. Starting with an overview of the disease and its current political, financial and technical context, this Milestones in Drug Therapy volume describes the history, chemistry, mechanisms of action and resistance, preclinical and clinical use, pharmacokinetics and safety and tolerability of the current range of antimalarial drugs. There is particular emphasis on artemisinins and related peroxides, as these drugs have now become the frontline treatment for malaria. Next generation antimalarials, molecular markers for detecting resistance, the importance of diagnostics and disease prevention are also covered in detail.
Download or read book Saving Lives Buying Time written by Institute of Medicine and published by National Academies Press. This book was released on 2004-09-09 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 50 years, low-cost antimalarial drugs silently saved millions of lives and cured billions of debilitating infections. Today, however, these drugs no longer work against the deadliest form of malaria that exists throughout the world. Malaria deaths in sub-Saharan Africaâ€"currently just over one million per yearâ€"are rising because of increased resistance to the old, inexpensive drugs. Although effective new drugs called "artemisinins" are available, they are unaffordable for the majority of the affected population, even at a cost of one dollar per course. Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance examines the history of malaria treatments, provides an overview of the current drug crisis, and offers recommendations on maximizing access to and effectiveness of antimalarial drugs. The book finds that most people in endemic countries will not have access to currently effective combination treatments, which should include an artemisinin, without financing from the global community. Without funding for effective treatment, malaria mortality could double over the next 10 to 20 years and transmission will intensify.
Download or read book Guidelines for the Treatment of Malaria Third Edition written by World Health Organization and published by World Health Organization. This book was released on 2015-08-13 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria remains an important cause of illness and death in children and adults in countries in which it is endemic. Malaria control requires an integrated approach including prevention (primarily vector control) and prompt treatment with effective antimalarial agents. Malaria case management consisting of prompt diagnosis and effective treatment remains a vital component of malaria control and elimination strategies. Since the publication of the first edition of the Guidelines for the treatment of malaria in 2006 and the second edition in 2010 all countries in which P. falciparum malaria is endemic have progressively updated their treatment policy from use of ineffective monotherapy to the currently recommended artemisinin-based combination therapies (ACT). This has contributed substantially to current reductions in global morbidity and mortality from malaria. Unfortunately resistance to artemisinins has arisen recently in P. falciparum in South-East Asia which threatens these gains. This third edition of the WHO Guidelines for the treatment of malaria contains updated recommendations based on a firmer evidence base for most antimalarial drugs and in addition include recommendation on the use of drugs to prevent malaria in groups at high risk. The Guidelines provide a framework for designing specific detailed national treatment protocols taking into account local patterns of resistance to antimalarial drugs and health service capacity. It provides recommendations on treatment of uncomplicated and severe malaria in all age groups all endemic areas in special populations and several complex situations. In addition on the use of antimalarial drugs as preventive therapy in healthy people living in malaria-endemic areas who are high risk in order to reduce morbidity and mortality from malaria. The Guidelines are designed primarily for policy-makers in ministries of health who formulate country-specific treatment guidelines. Other groups that may find them useful include health professionals and public health and policy specialists that are partners in health or malaria control and the pharmaceutical industry. The treatment recommendations in the main document are brief; for those who wish to study the evidence base in more detail a series of annexes is provided with references to the appropriate sections of the main document.
Download or read book Pharmacokinetic and Pharmacodynamic Profiles of Rapid and Slow Acting Antimalarial Drugs written by Qigui Li and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artemisinin and its derivatives are highly effective antimalarial drugs. These compounds combine potent and rapid antimalarial activity with a wide therapeutic index. An initiation of artemisinin resistance, described by a delayed parasite clearance time, is unlikely to cause high-level resistance. Artemisinins as a class demonstrate poor efficacy as monotherapy. This shortcoming can be overcome using oral artemisinin-based combination therapies (ACT) and intravenous-artesunate (IV-AS) in combination with slow-acting partner drugs. Pharmacokinetic and pharmacodynamic (PK/PD) evaluation demonstrates that the rapid efficacy of artemisinins is largely due to drug peak concentrations. Critical evaluation also demonstrates that AS is superior in PK/PD either following oral or intravenous administration when compared to the other rapid-acting artemisinins. This rapid efficacy and decreased mortality demonstrates that currently available artemisinins have a great advantage when combined with slow-acting antimalarial drugs for uncomplicated malaria or in sequential therapy with AS injection initially for severe and complicated malaria. Compared to other ACTs, dihydroartemisinin-piperaquine (DP) demonstrates a superior in PK/PD profile, most likely due to the long half-life of piperaquine. These findings will help us better understand the PK/PD profiles of rapid-acting (artemisinins) and slow-acting (piperaquine) drugs, and suggest how to best use ACTs in the future.

This book was released on 2020-04-24 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the many who serve in the United States Armed Forces and who are deployed to distant locations around the world, myriad health threats are encountered. In addition to those associated with the disruption of their home life and potential for combat, they may face distinctive disease threats that are specific to the locations to which they are deployed. U.S. forces have been deployed many times over the years to areas in which malaria is endemic, including in parts of Afghanistan and Iraq. Department of Defense (DoD) policy requires that antimalarial drugs be issued and regimens adhered to for deployments to malaria-endemic areas. Policies directing which should be used as first and as second-line agents have evolved over time based on new data regarding adverse events or precautions for specific underlying health conditions, areas of deployment, and other operational factors At the request of the Veterans Administration, Assessment of Long-Term Health Effects of Antimalarial Drugs When Used for Prophylaxis assesses the scientific evidence regarding the potential for long-term health effects resulting from the use of antimalarial drugs that were approved by FDA or used by U.S. service members for malaria prophylaxis, with a focus on mefloquine, tafenoquine, and other antimalarial drugs that have been used by DoD in the past 25 years. This report offers conclusions based on available evidence regarding associations of persistent or latent adverse events.

Download or read book Mechanisms of Drug Interactions written by Patrick F. D'Arcy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the years a number of excellent books have classified and detailed drug drug interactions into their respective categories, e.g. interactions at plasma protein binding sites; those altering intestinal absorption or bioavailability; those involving hepatic metabolising enzymes; those involving competition or antagonism for receptor sites, and drug interactions modifying excretory mechanisms. Such books have presented extensive tables of interactions and their management. Although of considerable value to clinicians, such publica tions have not, however, been so expressive about the individual mechanisms that underlie these interactions. It is within this sphere of "mechanisms" that this present volume specialises. It deals with mechanisms of in vitro and in vivo, drug-drug, drug food and drug-herbals interactions and those that cause drugs to interfere with diagnostic laboratory tests. We believe that an explanation of the mechanisms of such interactions will enable practitioners to understand more fully the nature of the interactions and thus enable them to manage better their clinical outcome. If mechanisms of interactions are better understood, then it may be pos sible for the researcher to develop meaningful animal/biochemical/tissue cul ture or physicochemical models to which new molecules could be exposed during their development stages. The present position, which largely relies on patients experiencing adverse interactions before they can be established or documented, can hardly be regarded as satisfactory. This present volume is classified into two major parts; firstly, pharmacoki netic drug interactions and, secondly, pharmacodynamic drug interactions.
