Quick Summary

Multidrug therapy, also known as combination therapy, is a medical approach that involves using more than one method, and specifically more than one drug, to treat a disease. This strategy is crucial in combating conditions where a single drug might be insufficient or lead to resistance.1

For instance, in treating tuberculosis, a serious bacterial infection of the respiratory system, using multiple drugs is essential to fight the disease effectively and prevent the bacteria from developing resistance. Similarly, in cancer treatment, anticancer drugs are categorized by their mechanisms of action, such as disrupting cell division or DNA, or by targeting specific growth signals. Often, a combination of these drugs, sometimes alongside surgery or radiation, is employed to maximize effectiveness and minimize the development of resistance. This approach acknowledges that different drugs can target cancer cells at various stages of their life cycle, offering a more comprehensive attack against the disease.23
