Drug discovery using natural products is a challenging task for designing new leads. The preclinical process of drug discovery can roughly be divided into three stages. This is where drug development … THE DRUG DISCOVERY PROCESS: A N OVERVIEW . The Drug Development Process. The average total cost per drug development varies from US$ 897 million to US$ 1.9 billion. Discovering and bringing one new drug to the market typically takes an average of 14 years of research and clinical development efforts. Caroline Horizny, PhD Tuesday, April 2, 2019 . Drug discovery and development is an expensive process due to the high costs of R&D and human clinical tests. Laws regulating drug marketing and development, government regulatory agencies with oversight of drug development and use, drug evaluation boards, drug information centres, and quality control laboratories have become part of the cooperative venture that produces and develops drugs. There are about 20,000-25,000 human genes, made up of 3 billion individual base pairs, the units of DNA. The Drug Discovery Process. Introducing a new drug to market is a complex and time-consuming process that can cost pharmaceutical companies an average $2.6 billion and ten years of research and development. The typical development time is 10-15 years. The process of discovering a drug involves many scientists running thousands of experiments over many years (Figure 1). Drug discovery typically begins with target identification – selecting a biochemical mechanism involved in a disease condition. Discovering a new drug has always been a long process that takes years. The process of drug discovery involves a combination of many disciplines and interests starting from a simple process of identifying an active compound. The first phase is the discovery phase. These lead compounds undergo more extensive optimization in a subsequent step of drug discovery called lead optimization (LO). Discovery often begins with target identification – choosing a biochemical mechanism involved in a disease condition. The drug discovery process is method of continuous process of the identification, synthesis, characterization, screening, and assays of drugs for therapeutic efficacy. Almost half a century ago, the world entered an apparent golden era of drug discovery. During this phase researchers try to understand the underlying mechanism or cause of a certain disease. sura.alkafaji@yahoo.com.
