  • Simultaneous Rapid HPLC Determination of Anticonvulsant Drugs in Plasma and Correlation with EMIT®
    ANNALS OF CLINICAL AND LABORATORY SCIENCE, Vol. 10, No. 1 Copyright© 1980, Institute for Clinical Science, Inc. Simultaneous Rapid HPLC Determination of Anticonvulsant Drugs in Plasma and Correlation with EMIT® RAYMOND S. RYDZEWSKI, M.S., RICHARD H. GADSDEN, P h .D.,* and CONSTANCE A. PHELPS, A.S.M.T. Division of Clinical Chemistry, Department of Laboratory Medicine, Medical University of South Carolina, Charleston, SC 29403 ABSTRACT A method is presented for measuring simultaneously five anti-convulsants (primidone, ethosuximide, phénobarbital, carbamazepine and diphenyl- hydantoin) in serum and plasma by high-performance liquid chroma­ tography (H PLC) usingalphenal (5 - allyl - 5 - phenyl - barbituric acid) as the internal standard. All five drugs are separated from each other and, in the case of primidone, from its metabolite, 2 - phenyl - 2 - ethyl - malondiamide. Total HPLC time for the separation is seven minutes. The chromatography is performed on a C-8 reverse phase column with a mobile phase consisting of acetonitrile/phosphate buffer (35/65) at 25°C. The eluted drugs are detected at 220 nm and quantitated from their peak heights relative to that of the internal standard. The lower limits of detection for each drug is 200 ng per ml for primidone, 1000 ng per ml for ethosuximide, 200 ng per ml for phéno­ barbital, 100 ng per ml for carbamazepine and 200 ng per ml for diphenyl- hydantoin. Analytical recoveries for the five drugs ranged from 97 to 107 percent. Correlation of results for 187 specimens by enzyme-immunoassay (EMIT) was 0.981 for primidone, 0.827 for ethosuximide, 0.975 for phéno­ barbital, 0.889 for carbamazepine and 0.990 for diphenylhydantoin.

    The World Health Organization is a specialized agency of the United Nations with primary responsibility for international health matters and public health. Through this organization, which was created in 1948, the health professions of some 190 countries exchange their knowledge and experience with the aim of making possible the attainment by all citizens of the world by the year 2000 of a level of health that will permit them to lead a socially and economically productive life. By means of direct technical cooperation with its Member States, and by stimulating such coopera­ tion among them, WHO promotes the development of comprehensive health services, the prevention and control of diseases, the improvement of environmental conditions, the development of human resources for health, the coordination and development of biomedical and health services research, and the planning and implementation of health programmes. These broad fields of endeavour encompass a wide variety of activities, such as developing systems of primary health care that reach the whole population of Member countries; promoting the health of mothers and children; combating malnutrition, controlling malaria and other communicable diseases including tuberculosis and leprosy; coordinating the global strategy for the prevention and control of AIDS; having achieved the eradication of smallpox, promoting mass immunization against a number of other preventable diseases; improving mental health; providing safe water supplies; and training health personnel of all categories. Progress towards better health throughout the world also demands international cooperation in such matters as establishing international standards for biological substances, pesticides and pharma­ ceuticals; formulating environmental health criteria; recommending international nonproprietary names for drugs; administering the International Health Regulations; revising the International Statistical Classification of Diseases and Related Health Problems and collecting and disseminating healih statistical information.

  • Early Drug Discovery and the Rise of Pharmaceutical Chemistry in a Classic Monograph (Figure 5)
    Drug Testing Historical and Analysis Received: 15 April 2011 Revised: 28 April 2011 Accepted: 28 April 2011 Published online in Wiley Online Library (www.drugtestinganalysis.com) DOI 10.1002/dta.301 Early drug discovery and the rise of pharmaceutical chemistry Alan Wayne Jones∗ Studies in the field of forensic pharmacology and toxicology would not be complete without some knowledge of the history of drug discovery, the various personalities involved, and the events leading to the development and introduction of new therapeutic agents. The first medicinal drugs came from natural sources and existed in the form of herbs, plants, roots, vines and fungi. Until the mid-nineteenth century nature’s pharmaceuticals were all that were available to relieve man’s pain and suffering. The first synthetic drug, chloral hydrate, was discovered in 1869 and introduced as a sedative-hypnotic; it is still available today in some countries. The first pharmaceutical companies were spin-offs from the textiles and synthetic dye industry and owe much to the rich source of organic chemicals derived from the distillation of coal (coal-tar). The first analgesics and antipyretics, exemplified by phenacetin and acetanilide, were simple chemical derivatives of aniline and p-nitrophenol, both of which were byproducts from coal-tar. An extract from the bark of the white willow tree had been used for centuries to treat various fevers and inflammation. The active principle in white willow, salicin or salicylic acid, had a bitter taste and irritated the gastric mucosa, but a simple chemical modification was much more palatable. This was acetylsalicylic acid, better known as Aspirin, the first blockbuster drug.
