Medicine development

Sepsis is a continuum of physiologic stages characterized by infection, systemic inflammation, and hypoperfusion with widespread tissue injury.1 The American College of Chest Physicians and the Society of Critical Care Medicine developed definitions to utilize for sepsis (Table 79—l).2 They provide physiologic parameters categorizing patients as having bacteremia, infection, systemic inflammatory response syndrome (SIRS), sepsis, severe sepsis, septic shock, or multiple-organ-dysfunction syndrome (MODS).2 Standardized definitions have been developed for infections in critically ill patients.3...

Phases of clinical trials and medicine development. Four phases of clinical trials and medicine development exist and are defined below. Each of these definitions is a functional one and the terms are not defined on a strict chronological basis. An investigational medicine is often evaluated in two or more phases simultaneously in different clinical trials. Also, some clinical trials may overlap two different phases. 

Research and development. When research and development are used together, it refers to the broadest definition for research (see above). Some people use the term research colloquially to include most or all of the scientific and medical areas (discovery, evaluation, and development) covered by the single term research and development. Medicine development has several definitions and, in its broadest definition, is exactly the same as the broad definition of research.

To monitor tumor response to capecitabine therapy noninvasively, Zheng and co-workers, from the Indiana University School of Medicine, developed the synthesis of the fluorine- 18-labeled capecitabine as a potential radiotracer for positron emission tomography (PET) imaging of tumors.28 Cytosine (20) was nitrated at the C-5 position with nitric acid in concentrated sulfuric acid at 85°C, followed by neutralization to provide 5-nitrocytosine (27) in moderate yield. This nitro pyrimidine was then carried through the glycosylation and carbamate formation steps, as shown in the Scheme below, to provide the 6/s-protected 5-nitro cytidine 28 in 47% for the three-step process. Precursor 28 was then labeled by nucleophilic substitution with a complex of 18F-labeled potassium fluoride with cryptand Kryptofix 222 in DMSO at 150 °C to provide the fluorine-18-labe led adduct. This intermediate was not isolated, but semi-purified and deprotected with aqueous NaOH in methanol to provide [l8F]-capecitabine in 20-30% radiochemical yield for the 3-mg-scale process. The synthesis time for fluorine-18 labeled capecitabine (including HPLC purification) from end of bombardment to produce KI8F to the final formulation of [18F]-1 for in vivo studies was 60-70 min. 

The long quest for blood-compatible materials to some extent overshadows the vast number of other applications of polymers in medicine. Development and testing of biocompatible materials have in fact been pursued by a significant number of chemical engineers in collaboration with physicians, with incremental but no revolutionary results to date. Progress is certainly evident, however the Jarvik-7 artificial heart is largely built from polymers [34]. Much attention has been focused on new classes of materials, such...

There is little wonder then that we have a drug-conscious society where medicines developed for therapeutic advances are abused and where drugs for which there is no rational or therapeutic use are taken in ever increasing quantities by the weak, the poorly informed, the mentally disturbed, and the constitutionally inadequate. Inevitably, the pharmaceutical industry is blamed for these shortcomings of society because it happens to be the most visible target in an era when many (public and political) refuse to discriminate between medical use and drug abuse. 

Joseph Lister is known as the founder of antiseptic surgery, a significant advance in medicine developed in the nineteenth century. Infection of wounds and surgical incisions was a major cause of hospital deaths before Lister developed a way of preventing these infections with chemical antiseptics. His discovery made surgery much safer and permitted surgeons to perform operations not previously attempted because of the high risk of fatal infections. 

The World Wildlife Fund estimates that plants have contributed more than 7000 compounds produced by the pharmaceutical industry in industrialized nations. The folk medicine and indigenous medicine developed by different native cultures across the world is based mainly on herbs. Indeed, more than 200 of the herbal drags listed in the U.S. Pharmacopoeia were used by Indians in Mexico, the West Indies, and Central and South America. The popular traditional medical systems—Chinese medicine, Ayurveda, and Unani—have suggested cancer cures involving herbal medicine. Dr. 

The steady stream of new medicines developed makes human life better. However, drags approved decades ago did not go through the same strict procedure and were not subjected to the same scrutiny. Dozens of medicines approved before 1940 are still sold. However, this apparent contradiction is not a cause for alarm. All of these early medicines were widely used in the last 70 years, and experience with thousands (often maity more) patients show their effect and safety. This is much better than any current tests, where the time scales are imderstandably much shorter (Fig. 3.44).

The European - United States Paediatric Formulation Initiative (Eu-US PEI) has established that there is a pressing need for a single authoritative comprehensive database of adverse effects of excipients for paediatrics. Safety and Toxicity of Excipients for Paediatrics (STEP) Database holds all the animal toxicity and human health data, regulatory information and toxicological reviews of excipients. STEP acts as repository for all the scientific communities to share the data for better understanding and paediatric medicines development (European Paediatric Eormu-lation Initiative. STEP Database. See [3]).
