What is a characteristic of the continuous dosing method for chemotherapy?

1. Allowed for larger cumulative dosages

2. Minimizes toxicity effects with fewer administrations

3. Used exclusively for intravenous treatments

4. Administers drugs in a min concentration

The correct answer is: Administers drugs in a min concentration

In chemotherapy, the continuous dosing method is characterized by the administration of drugs over an extended period of time, often aiming to maintain constant therapeutic drug levels in the bloodstream. This approach allows for the use of lower concentrations of the drug during each administration, which can be crucial for minimizing toxicity while still providing effective treatment. By maintaining a steady concentration, it helps to optimize the drug's effectiveness against cancer cells while reducing the peaks and troughs associated with intermittent dosing. It's important to note that maintaining a minimum concentration of the drug can help ensure that it's always available to act on the cancer cells, potentially improving treatment outcomes and reducing the likelihood of cancer cell resistance developing. Other options highlight aspects that may not align with the primary purpose and rationale of continuous dosing in chemotherapy.
