Drug synergy is a research area that focuses on the interaction between two or more drugs that results in a greater therapeutic effect than would be expected based on the individual effects of each drug. This synergistic effect can occur through a variety of mechanisms, including enhanced drug delivery, modulation of drug metabolism, and targeting multiple pathways involved in a disease process. Studying drug synergy is important for improving the effectiveness of drug treatments, reducing side effects, and developing more personalized and precise medication regimens.
