Drug mechanism research involves studying how drugs interact with the body at a molecular level to produce their effects. This includes investigating how drugs bind to specific receptors or enzymes, alter biochemical pathways, and ultimately lead to physiological responses. Understanding drug mechanisms is essential for developing new and more effective medications, as well as for predicting potential side effects or drug interactions. Researchers in this field use a variety of techniques, such as molecular modeling, biochemical assays, and animal studies, to elucidate the mechanisms of action of different drugs.
