Available in PDF, EPUB and Kindle. Book excerpt: Nitroglycerin and other organic nitrates have been used for over a century in the treatment of angina pectoris. Millions of patients, throughout the world, have placed nitroglycerin tablets under the tongue and have experienced rapid and dramatic relief from the chest pain that frequently occurs as a manifestation of disease of the coronary arteries. The empirical observation of the safe use of nitrates for tile alleviation of the symptoms of angina have led to their widespread medical acceptance. The use of organic nitrates preceded any knowledge of their mechanism of action or their ultimate metabolic fate. Thus, more simply stated, although sub lingual nitrates helped the patients, little was known concerning what these drugs do to the body or what the body does to the drugs. A substantial number of investigators have focused on these questions especially during the last two decades. We now have considerably more insight into the pathways of degradation of organic nitrates and the relationship of the metabolic processes to the biological action of these agents. Similarly, considerable effort has been expended in understanding the mechanism of action of these agents directly on vascular smooth muscle and on cardiac work and performance. Finally, there is a more substantive understanding of the physiology of the coronary circulation as well as the" pathophysiologic manifestations of myocardial disease.

This book was released on 2013-08-07 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2010 in the subject Medicine - Pharmacology, Pharmacy, University of Dhaka (M. Pharm, in Pharmaceutical Technology), language: English, abstract: The aim of the present studies was to develop and characterize 2.6 mg sustained release matrix tablets of Nitroglycerin. Tablets were prepared by direct compression method. Methocel K15M CR and Methocel K100LV CR polymers were used as rate retarding agents in nine formulations (F-1 to F-9). The granules were evaluated for angle of repose, loose bulk density, tapped bulk density, Carr’s index, Hausner ratio, moisture content, total porosity and assay. The tablets were subjected to diameter, thickness, assay, uniformity of content, assay after 1Month at 40°C+75%RH, hardness, friability, and in vitro dissolution studies. The granules showed satisfactory flow properties, compressibility, and drug content. All the tablet formulations showed acceptable pharmacotechnical properties and complied with pharmacopoeial specifications for tested parameters. The in vitro dissolution study was carried out for 8 hour using USP-2009 Apparatus-I (Rotating basket method) in distilled water as the dissolution medium. The release mechanisms were explored and explained by Zero order, First order, Higuchi, Korsmeyer-Peppas and Hixson-Crowell equations. Nine formulations were prepared by using three variable ratio of two polymers; Methocel K15M CR (25%, 20% and 15%) and Methocel K100LV CR (15%, 10% and 5%) where all the formulations (F-1 to F-9) contained 0.5% colloidal silicon dioxide and 1% magnesium stearate. Among these nine formulations, six formulations; F-2 (Methocel K15M CR: Methocel K100LV CR = 25% : 10%), F-3 (Methocel K15M CR : Methocel K100LV CR = 25% : 5%), F-4 (Methocel K15M CR : Methocel K100LV CR = 20% : 15%) F-5 (Methocel K15M CR: Methocel K100LV CR = 20% : 10%), F-6 (Methocel K15M CR : Methocel K100LV CR = 20% : 5%) and F-7 (Methocel K15M CR : Methocel K100LV CR = 15% : 15%) met the official specification of release profile. It was also found that the type and the amount of polymers significantly affect the time required for 50% (T50% or MDT) of drug release, release rate constant and diffusion exponent. Higher the MDT value indicates a higher drug retaining capacity of the polymers and vice-versa. Kinetic modeling of in vitro dissolution profiles revealed the drug release mechanism of all proposed formulations followed anomalous type or non-Fickian transport (n>0.43 and n

Does the identification number 1035 indicate ethane or butane? What is the difference between natural gas transmission pipelines and natural gas distribution pipelines? If you came upon an overturned truck on the highway that was leaking, would you be able to identify if it was hazardous and know what steps to take? Questions like these and more are answered in the Emergency Response Guidebook. Learn how to identify symbols for and vehicles carrying toxic, flammable, explosive, radioactive, or otherwise harmful substances and how to respond once an incident involving those substances has been identified. Always be prepared in situations that are unfamiliar and dangerous and know how to rectify them. Keeping this guide around at all times will ensure that, if you were to come upon a transportation situation involving hazardous substances or dangerous goods, you will be able to help keep others and yourself out of danger. With color-coded pages for quick and easy reference, this is the official manual used by first responders in the United States and Canada for transportation incidents involving dangerous goods or hazardous materials.
Download or read book Nitrates III written by P. Lichtlen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pharmacological and clinical research on nitrates continues to be of growing interest in many centers. This is surprising in view of the fact that their favorable effects in angina pectoris were described by Brunton and by Murrell in the Lancet more than 100 years ago. As expected, a host of new information has been collected since the two previous symposia on nitrates held in Stockholm in 1975 and Berlin in 1978. New insights were gained into the pharmacology, pharmacokinetics and pharmacodynamics of nitrates, as well as into their clinical effects in acute and chronic ischemic heart diseases and in severe congestive heart failure. Relatively little progress, however, was observed in research into the basic action of nitrates. Although most investigators agree that intracellular sequestration of calcium is probably the main mechanism by which nitrates lead to the reduction of vascular smooth muscle tone, the exact site of their action still remains undefined. In contrast, dose-dependent differences in venous and arteriolar tone have long been clearly established. Treatment was again in the main stream of discussion. The question of tolerance following long-term administration was discussed in depth and the term "pseudotolerance" was introduced to describe the adaptation of the body's circulatory system to chronic vasodilation. This is especially important in long term prophylactic antiischemic treatment in stable, as well as in unstable angina pectoris (i.e. during increased vasomotor tone - spasm).

Book excerpt: Rushmore McKenzie, a retired St. Paul policeman and unexpected millionaire, often works as an unlicensed P.I., doing favors as it suits him. When graduate students Ivy Flynn and Josh Berglund show up with a story about $8 million in missing stolen gold from the ‘30s, McKenzie is intrigued. In the early 20th century, St. Paul, Minnesota was an open city —a place where gangsters could come and stay unmolested by the local authorities. Frank "Jelly" Nash was suspected of masterminding a daring robbery of gold bars in 1933, but, before he could unload it, he was killed in the Kansas City Massacre. His gold, they believe, is still somewhere in St. Paul. But they aren't the only ones looking. So are a couple of two-bit thugs, a woman named Heavenly, a local big-wig, and others. When Berglund is shot dead outside of Ivy's apartment, the treasure hunt turns unexpectedly deadly. In this hard-boiled mystery from David Housewright, Mac McKenzie is looking for more than a legendary stash from seventy-five years ago---he's looking for a killer and the long hidden truth behind Jelly's gold.
Download or read book Early Interventions in Acute Myocardial Infarction written by Elliot Rapaport and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the pathophysiology of acute myocardial infarction has grown enormously in recent years. This has led to an increasingly aggressive approach to management, designed to blunt the extent of infarction by salvaging acutely ischemic myocardium. Alternatives now include throm bolysis, PTCA with and without prior thrombolysis, and emergency bypass surgery, as well as the more aggressive use of a variety of drugs. This book consists of a series of chapters by experienced cardiologists and cardiovascular surgeons that present today's state of the art in managing acute myocardial infarction. It is written with the purpose of presenting practical approaches of value to the clinician related to the more complex problems faced in dealing with patients undergoing myocardial infarction. xi EARLY INTERVENTIONS IN ACUTE MYOCARDIAL INFARCTION 1. MANAGEMENT OF ARRHYTHMIAS IN THE CORONARY CARE UNIT NORA GOLDSCHLAGER, RODERICK WOODS, AND NEAL BENOWITZ With the advent of coronary care units, mortality from cardiac arrhythmias occurring during acute myocardial infarction has been unquestionably and dramatically reduced. In addition, continuous electrocardiographic monitoring has resulted in the recognition of specific arrhythmias related to acute ischemic heart disease and thus to the development of appropriate strategies for their management. This chapter will review certain specific aspects of those bradyarrhythmias and atrial and ventricular tachyarrhythmias that are seen most commonly in acute myocardial infarction. Pharmacologic therapy, including the use of some of the newer antiarrhythmic agents, will be discussed, as will pacemaker ther apy of both bradyarrhythmias and tachyarrhythmias.
