Combination therapy refers to a medical treatment approach that involves using two or more different medications, treatments, or interventions simultaneously to address a particular health condition. The idea behind combination therapy is that by using multiple approaches at once, the overall effectiveness of the treatment can be improved and the desired outcome achieved more quickly than if only one method were used alone. Combination therapy is often used in the management of chronic conditions such as HIV/AIDS or cancer where a combination of drugs may work together to attack the disease from multiple angles, reducing the likelihood of drug resistance and improving patient outcomes.
