Drug design

Definition

Drug design is the process of discovering and developing new medications by understanding and manipulating molecular interactions between drugs and biological targets. This involves identifying the specific molecular mechanisms of action that a drug can influence, which ultimately leads to the creation of more effective and targeted therapies. The goal of drug design is to optimize pharmacological properties and minimize side effects, making it a crucial aspect of modern pharmaceutical development.
