Drug combination research involves investigating the effectiveness and safety of using two or more medications together to treat a particular disease or condition. This approach is based on the idea that combining different drugs with complementary mechanisms of action can lead to improved therapeutic outcomes, such as enhanced efficacy, reduced side effects, and prevention of drug resistance. Researchers in this area explore the synergistic effects of drug combinations, optimize dosing regimens, and identify potential interactions between different drugs. Drug combination research plays a crucial role in the development of novel treatment strategies for complex diseases, such as cancer, infectious diseases, and autoimmune disorders.
