Final answer:
Using multiple drugs prescribed together can minimize the dosage required of each to be effective, lower the dose, and reduce resistance to therapy.
Step-by-step explanation:
True.Using multiple drugs prescribed together can indeed minimize the dosage required of each to be effective, lower the dose, and reduce resistance to therapy. This approach is often referred to as combination therapy. When multiple drugs with different mechanisms of action are used together, they can target different aspects of the infection or disease, resulting in enhanced effectiveness and reduced chances of developing resistance. For example, in the case of antibiotics, combination therapy can be used to treat bacterial infections. The combination of two antibiotics, such as trimethoprim and sulfamethoxazole (Bactrim), can have a synergistic effect, meaning their combined action is greater than the sum of their individual actions. This allows for a lower dose of each drug to be used, minimizing potential side effects and reducing the likelihood of resistance.
