Drug development is the process by which new medications are discovered, developed, and brought to market for the treatment of various diseases and medical conditions. This process involves extensive research and testing to determine the safety and efficacy of potential drugs before they can be approved for use by regulatory agencies such as the FDA. Drug development often involves a combination of laboratory research, preclinical testing on animals, and clinical trials on human subjects. It can take many years and cost billions of dollars to bring a new drug from initial discovery to final approval and commercialization. The goal of drug development is to provide safe and effective treatments for patients in need, ultimately improving public health and quality of life.
