Drug Discovery and Development

Drug discovery and development refers to the process of finding new therapeutic compounds for the treatment, prevention or management of diseases and making these compounds available safely and effectively. This process is a multidisciplinary effort that involves both basic scientific research and advanced technologies.

The drug development journey often begins with understanding the biological mechanisms underlying a disease. Researchers identify specific target proteins or genes that play a role in these mechanisms. Potential compounds that might affect these targets are then screened from chemical libraries or designed in laboratories. The discovered candidate molecules are tested in vitro and in animal models to evaluate their effectiveness, toxicity levels and pharmacokinetic properties. This stage is critical to determining whether a drug is safe enough for human trials.

Afterwards, clinical trials begin, which is the most comprehensive and expensive phase of the drug development process. First, safety tests are performed in a small number of healthy volunteers. Efficacy and side effects are then investigated in a larger group of patients with the disease. In the final stage, large-scale studies are conducted involving thousands of patients to prove the effectiveness and safety of the drug.
