Drug research encompasses several diverse disciplines united by a common goal, namely the development of novel therapeutic agents. The search for new drugs can be divided functionally into two stages: discovery and development. The former consists of setting up a working hypothesis of the target enzyme or receptor for a particular disease, establishing suitable models (or surrogate markers) to test biological activities, and screening the new drug molecules for in vitro and/or in vivo biological activities. In the development stage, efforts are focused on evaluation of the toxicity and...

Malaria remains a major cause of death and disability worldwide and is endemic to much of Africa, South America, and southeast Asia. Other malaria risk areas include the Middle east, some countries in Central America and Polynesia, with most other continents virtually free of the disease. The choice between RDTs and microscopy depends on local circumstances, including the skills available, patient case-load, epidemiology of malaria and the possible use of microscopy for the diagnosis of other diseases. Where the case-load of fever patients is high, microscopy is likely to be less expensive...

HERBAL medicine is still the mainstay of about 75-80% of the world population, mainly in the developing countries, for primary health care because of better cultural acceptability, better compatibility with the human body and lesser side effects. However, the last few years have seen a major increase in their use in the developed world. In Germany and France, many herbs and herbal extracts are used as prescription drugs and their sales in the countries of European Union were around $ 6 billion in 1991 and may be over $ 20 billion now. In USA, herbal drugs are currently sold in health food...

Jungle fever is a mosquito-borne infectious disease of humans caused by eukaryotic protists of the genus Plasmodium. It is widespread in tropical and subtropical regions, including much of Sub-Saharan Africa, Asia and the Americas. Malaria is prevalent in these regions because of the significant amounts of rainfall and consistent high temperatures; warm, consistent temperatures and high humidity, along with stagnant waters in which their larvae mature, provide mosquitoes with the environment needed for continuous breeding . The cause of the disease is a protozoan, discovered in 1880 by...

Information technology provides several databases, data analysis tools, and knowledge extraction techniques in almost every facet of life. In pharmaceutical sciences, several successful attempts are being made under the umbrella of pharmacoinformatics (synonymously referred to as pharmainformatics).Chemoinformatics and bioinformatics contribute directly to drug discovery through virtual screening. Topics like neuroinformatics, immunoinformatics, vaccine informatics, and biosystem informatics contribute indirectly by providing necessary inputs for pharmaceutical design in this area. Topics...
