Pharmaceutical industry sources

One appHcation patented ia 1989 is the injection of sodium alumiaate into silica-containing formations for enhanced petroleum recovery (39). Additionally, the pharmaceutical industry uses sodium alumiaate as an alkaline source of aluminum for the production of certain antacids (40). 

The pharmaceutical industry has employed materials of plant and animal origin as sources of drugs. The industry has utilized the life processes of either plants or animals and microorganisms to produce medicinal and antibiotic products. 

Caldum gluconate is one of the relatively few soluble caldum salts and is used in the pharmaceutical industry as a source of caldum for patients with caldum defidency. Many drugs are supplied as the gluconate derivatives. Other gluconates such as iron gluconate can be used, in this case to treat iron defidency. 

Pharmacopoeia publications provide a final important source of information for the pharmaceutical industry, regulatory authorities, and the healthcare professions. These are concerned with establishing quality standards. These publications include monographs that define specifications for the purity and identity of established pharmaceutical ingredients, both active and non-active, together with recognised analytical methods that may be used to evaluate them. The most relevant are the United States Pharmacopoeia (USP) and the European Pharmacopoeia (Ph.Eur). 

For thousands of years, nature has provided humankind with a large variety of materials for the most diversified applications for its survival, such as food, energy, medicinal products, protection and defense tools, and others. The pharmaceutical industry has benefitted from such diversity of biomaterials and has exploited the use of natural products as sources of both drugs and excipients. One example of a promising biomaterial for pharmaceutical use is xylan, a hemicellulose largely found in nature, being considered the second most abundant polysaccharide after cellulose. 

Comprehensive physicochemical characterization of any raw material is a crucial and multi-phased requirement for the selection and validation of that matter as a constituent of a product or part of the product development process (Morris et al., 1998). Such demand is especially important in the pharmaceutical industry because of the presence of several compounds assembled in a formulation, such as active substances and excipients, which highlights the importance of compatibility among them. Besides, variations in raw materials due to different sources, periods of extraction and various environmental factors may lead to failures in production and/or in the dosage form performance (Morris et al., 1998). Additionally, economic issues are also related to the need for investigating the physicochemical characteristics of raw materials since those features may determine the most adequate and low-cost material for specific procedures and dosage forms. 

Vanillosmopsis erythropappa Schultz-Bip. is a component of the Atlantic coastal forest in Brazil, where it is exploited as a source of an essential oil used in the pharmaceutical industry. A survey of specimens from four locations showed markedly different compositions of their essential oil fraction (Lopes et al., 1991). The compounds identified were bisabolol [160], costunolide [161], eremanthine [162], and five related compounds, six compounds based upon the cyclocostunolide skeleton [163], and the two esters 15-deoxygoyazenolide [164] and lychnopholide [165]... 

The Internet, for many professionals, has become a favorite, convenient source for free information. The Internet is a vehicle to access a diverse array of information sources, including federal and state government documents and regulations, statements, opinions and guidelines from associations and organizations, and pharmaceutical industry documents. While the Internet is indeed powerful, it is a retrieval mechanism and the WWW site itself is the resource to be considered for relevance to the current search. The convenience of WWW resources can be quickly overshadowed by the time invested in the search and following linkages. 

One advantage of whole-cell biotransformation that has not been addressed adequately in this chapter is the ability to modify compounds with complex structure, such as natural products. Natural products are ideal substrates for biotransformation reactions since they are synthesized in a series of enzymatic reactions by the whole cells. The modification of natural products by biotransformation has been reviewed recently by Azerad [ 13] and a majority of the modifications were carried out by whole-cell biotransformations. Additional examples of modification of natural products by whole-cell biotransformations can also be found in the review article by Patel [2]. Natural products are an important source of new drugs and new drug leads [53]. The use of biotransformation, especially whole-cell biotransformation, in modification of natural products for lead optimization and generating libraries of derivatives for S AR and screening studies is important for the pharmaceutical industry. 

There are however problems with the concept of ADHD as a clinical disorder. In the USA the number of child prescriptions for methylphenidate rose by 500% in the mid-1990s (Maisto et al., 1998), while an even more dramatic rise in prescriptions from a near-zero baseline has occurred during this period in the UK. Although profitable for the pharmaceutical industry, the reasons for this dramatic increase in clinical diagnoses need to be uncovered. Possible sources include artificial food additives, junk foods or otherwise poor diets. Another is less appropriate modes of play, including computer... 

An alternative to the extraction of intact PHA polymer is the isolation of PHA monomers, oligomers, or various derivatives such as esters [74]. PH As are composed of stereo-chemically pure P-3-hydroxyacids, and therefore can be used as a source of optically pure organic substrates for the chemical and pharmaceutical industry [79]. In this protocol, the defatted cake containing PHA polymer would be chemically treated to obtain the PHA derivatives. For example, transesterification of the meal with methanol would give rise to methyl esters of 3-hydroxyalkanoic acids. The PHA derivatives would then be separated from the meal with appropriate solvents. One potential disadvantage of this method is the potential alteration of the quality of the residual meal if the harsh chemical treatments required for the production of PHA derivatives lead to protein or amino acid breakdown. 

There are distinct advantages of these solvent-free procedures in instances where catalytic amounts of reagents or supported agents are used since they provide reduction or elimination of solvents, thus preventing pollution at source . Although not delineated completely, the reaction rate enhancements achieved in these methods may be ascribable to nonthermal effects. The rationalization of microwave effects and mechanistic considerations are discussed in detail elsewhere in this book [25, 193]. A dramatic increase in the number of publications [23c], patents [194—203], a growing interest from pharmaceutical industry, with special emphasis on combinatorial chemistry, and development of newer microwave systems bodes well for micro-wave-enhanced chemical syntheses. 

Increasing environmental concerns and dwindling supplies of raw materials and energy sources mean that there is now a significant pressure to introduce cleaner processing in the chemical and pharmaceutical industries. 

After overcoming the instability of the thermospray ionization source, a sensitivity of 2 ng/mL was achieved with a calibration range of 10 to 103 ng/mL for human plasma samples. In recent years, the online SPE LC/MS/MS technology has matured and is now easy to build and use. It is used widely in the pharmaceutical industry (Jemal et al. 2000 Hsieh 2004 Hennion 1999). 

Notwithstanding the intellectual challenges posed by the subject, the main impetus behind the development of computational models for turbulent reacting flows has been the increasing awareness of the impact of such flows on the environment. For example, incomplete combustion of hydrocarbons in internal combustion engines is a major source of air pollution. Likewise, in the chemical process and pharmaceutical industries, inadequate control of product yields and selectivities can produce a host of undesirable byproducts. Even if such byproducts could all be successfully separated out and treated so that they are not released into the environment, the economic cost of doing so is often prohibitive. Hence, there is an ever-increasing incentive to improve industrial processes and devices in order for them to remain competitive in the marketplace.
